A muscular girl is presented to the passionate world of crossover anime.

In short, it's hard to say who is stronger between Koyasu and Kanon, but Koyasu's strength is undeniable, and Baki has realized that he is about to face a tough battle.

"I can't believe there's an uncle like you in the world..." Baki was more pleased than worried: "I'm also very happy that you're taking Miss Ye's place."

Shingoro Koyasu rolled his dead fish eyes and smiled at Baki: "Oh dear, I've just been slacking off for too long, so I came out for a stroll to keep my body from rusting, and ended up meeting a young genius like you. You're the son of the legendary 'Great Fiend'~"

"You...have you met Yujiro before?" Baki became curious. Could the powerful figure before him be the "strongest creature in the world"?

The answer was no. Shingoro Koyasu shrugged. "I've heard of Yujiro Hanma's name. I should have met him, but I have another target to chase. I don't want to cause any trouble before I get past that person... Heh, meeting the 'son of the giant' today can make up for some of my regrets, can't it?"

"...Alright, I'll give it my all and have a good fight with you, Uncle!"

"Then let's go... pfft!"

Baki had already assumed a fighting stance. After exchanging a few words, Koyasu, annoyed that Baki was taking so long to make a move, beckoned to him with his finger and was immediately punched.

Baki's attack was quite swift, and the punch was very powerful, causing Koyasu to stagger.

Uh, just one stumble?

Kanon had fought Baki before, and she knew that Baki's attacks were extremely powerful. If a direct hit to the head, a vital point, was hit, it would be a very bad thing. Could it be that Shingoro Koyasu was also proficient in "force absorption" or "indestructible body"?

No, Koyasu only withstood the blow with his physical strength. After being hit in the head, he immediately regained his balance: "Hey, little brat, you can even do surprise attacks... Pfft!" Before he could finish speaking, he was slapped in the face by Baki again.

Baki, having been hit twice, continued his pursuit, and with his third strike, he leaped up and stomped on Koyasu's face with both feet—"thud!"

However, the three-hit combo only forced Koyasu back two steps, which was far too weak an effect.

In the lounge, Hana exclaimed in surprise, "My God! Just who is this guy?"

"Shingoro Koyasu comes from Meido Kaikan, one of the top karate organizations in Japan, second only to our Shinshin-kai and Rokujin-kaikan." While Soryujin and others were explaining to Kanon, Katsumi Guji was also explaining the situation to his teammates Retsu Kaioh and Kaia: "Actually, Meido Kaikan's overall strength isn't that strong. The reason it was ranked so high before is because of Shingoro Koyasu's existence. He only suffered one defeat in his life, which was ten years ago in the Rokujin-kaikan tournament when he lost by half a move to 'the strongest man of the yellow race,' Shinji Shinyasu, resulting in a point deduction. In other words, Koyasu has never been knocked out. For a long time, he was a strong contender for the strongest martial artist in Japan. It's just that he's gotten older in recent years, so he withdrew from the front lines and has been silent for a long time."

Finally, Katsumi concluded regarding the situation in this battle: "In short, even though Koyasu is nearly fifty years old and past his physical peak, he is still Baki's most formidable opponent. This battle is very dangerous."

Shingoro Koyasu was overwhelmed by Baki's rapid attacks. The first blow was somewhat unexpected, but the next two seemed to be deliberately endured, as he wanted to see just how powerful Baki's attacks were. Now that the test was over, he was... a little disappointed.

"The so-called son of Yujiro Hanma... is this all?"

Baki certainly dislikes Yujiro, but he also can't tolerate Yujiro being looked down upon—that most terrifying man is someone Baki Hanma will personally defeat!

So, enraged, Baki charged at Koyasu again, throwing a punch—but it missed! It turned out that Shingoro Koyasu had also started exchanging blows with Baki.

"Haha, I'm getting old." Despite his rough appearance and strength, Shingoro Koyasu is surprisingly skilled when it comes to fighting, gradually putting Baki at a disadvantage. However, he was still not satisfied: "If it were me ten years ago, I might have slapped you to the ground."

Now... Koyasu can't withstand Baki's attacks for long. He has to keep up with him, find his weaknesses, and then seize the right opportunity to land a punch on Baki.

"Bang!" Baki was punched and staggered backward, but his steps became faster and faster. In the end, he rolled backward on the ground and continued to retreat until he reached the edge of the field. With a "crack", he crushed half of the fence before stopping his momentum.

Zi'an's seemingly weak punch had such force.

"Phew—" Baki let out a long breath: "Uncle, you're so strong!"

"Hahaha, isn't that obvious?" Koyasu, known as the "Lion King," had an overbearing personality. He accepted Baki's praise without rushing to pursue him. The king of beasts had his pride, and he would give the weaker party more time to prepare. If they wanted to admit defeat, he had no objection.

But Baki was not one to admit defeat! He charged at Koyasu again and launched an attack.

"Hmph, little brat, you're certainly full of fighting spirit." Zi'an's tone was relaxed, and his responses were even more casual. His moves were not flashy, but they were very precise and solid. None of Baki's attacks could penetrate Zi'an's defense.

Baki is a "hexagonal fighter," excelling in speed, strength, and skill with no obvious weaknesses. If one had to pinpoint a weakness, it would probably be his slightly inferior height, weight, and reach. The kind of "hexagonal fighter" he fears most is precisely another "hexagonal fighter" without weaknesses, such as Shingoro Koyasu.

As a super strong player in the field of karate, Shingoro Koyasu is not as wild as he appears. In fact, Kanon can even see the shadow of Gensai Kuroki in him.

"I wonder how Uncle Kuroki is doing in America. It's been so long since I contacted him." Hanon began to miss her friend. As for the battle in front of her, there was not much suspense anymore. She felt that this was like Kuroki Gensai fighting against her when she first started learning martial arts. The gap in experience and level was too big, which was the most difficult thing for a martial artist to make up for.

Koyasu parried Baki's attacks with simple efficiency, but suddenly a bloody gash appeared on his face. It turned out that Baki's arm swung out like a whip with incredible speed, leaving Koyasu no time to react. He could only slightly turn his head to avoid a vital spot and suffered a minor injury.

"Enough!" The Lion King's pride allowed his opponent to gracefully withdraw, but it could not tolerate such provocation! Shingoro Koyasu's straight punch shot out like lightning, and before Baki could retract his "whip strike," he sent him flying.

Ultimately, the skill gap between the two sides is too large.

Author's Note: There will be two more chapters tonight, but I estimate this battle won't last until the next chapter.

Section 654, Chapter 647: Hades is definitely stronger than Triceratops!

Baki Hanma, lying on the ground, vomited a mouthful of blood. Accompanied by severe dizziness, he was almost unable to stand up.

Shingoro Koyasu, this martial artist who suddenly appeared, his punch was terrifyingly powerful!

Perhaps it's true, as Koyasu himself said, that ten years ago, he could have knocked out Baki with a single slap.

But now it is ten years later, and Koyasu has grown old. His skills are more refined, but his physical condition has inevitably declined. Even though he is a fierce warrior who can move mountains and cross the North Sea, the "Lion King" is not a "tiger" after all, and does not have the "superhuman muscles" of Wakatsuki, who gets stronger with age.

So after struggling for a while, Baki managed to stand up unsteadily and charged at Koyasu again.

What use is this...? Shingoro Koyasu's strength is astonishing. Even a fully healthy Baki couldn't defeat him, let alone now?

Well, after all, it's Baki Hanma. With a soft "Eh!" from Koyasu, Baki's movements suddenly accelerated. His forward momentum instantly shifted, and he circled behind Koyasu, grabbing the "Lion King" around the waist—a devil's back throw! A German back throw!

The weak, ordinary people, and ordinary strong people cannot awaken the bloodline of the Hanma family. However, a true strong person, strong enough to reach the level of Kanon or Koyasu, is enough to awaken Baki's potential and make him more like Hanma Yujiro.

"After all, there's still this trick up your sleeve." Hanon scratched her face. She was very familiar with "Oni Back" and was really looking forward to Baki's success. Koyasu's strength was beyond her expectations. To be honest, Hanon also felt some pressure. Baki's "Oni Back" had fought against Hanon's "Valkyrie Mode". If it could also work on Koyasu, it would give Hanon some psychological comfort.

So, was Baki successful?

Baki was halfway to success with his move. The "Demon Back" technique brought extraordinary power, and Baki really managed to flip Koyasu's huge body onto his back! It should be noted that Koyasu's official weight is 132 kilograms, and during the years he went into hiding, he gained a few more kilograms due to old age and lack of combat experience, making him a truly strong man.

As for the other half of Baki's failed back throw, Koyasu's reaction was truly quick. After being thrown, his hands were still free, so he pushed hard on Baki's shoulder. With a "crack" sound, Baki's right shoulder dislocated, and his movement was also deformed. Koyasu was not thrown to the ground solidly, but landed on his side instead of his back. By using recovery techniques, the damage was greatly reduced.

Koyasu rolled away, escaping Baki's pursuit... Actually, Baki had no intention of pursuing him; he needed a little time to put his dislocated shoulder back in place. So when Koyasu got up again, the two heroes were still facing off.

"Haha, now you're finally starting to look decent." The fall caused blood to appear at the corner of Shingoro Koyasu's mouth. He wiped it away, becoming even more excited: "If this is your level, then Yujiro Hanma can really look forward to it~ It's a pity I'm too old, otherwise I wouldn't have suffered this injury."

Koyasu wasn't bragging; he's right-handed, so his right arm is stronger, which is why the pressure he just applied dislocated Baki's right shoulder. If it were ten years ago, when both of Koyasu's arms were stronger, Baki would have dislocated both shoulders, and wouldn't have been able to complete half of the tumble and injure Koyasu.

"But this should end here." Zi'an realized the shock from his injury was quite severe; he couldn't wipe it clean in one go, and blood was flowing from the corner of his mouth again. "Little brat, don't be so arrogant. I'll finish you off in the next move!"

Is Shingoro Koyasu long-winded? No, he rarely goes on at length. He just likes to say a few jokes. In reality, he is a man of his word with excellent credibility. A lion king can be lazy, but keeping his word and fulfilling his promises is the mark of a true king.

With these words, Shingoro Koyasu's momentum surged once again. In Baki's perception, his opponent was already about the same level as the enraged Yujiro Hanma. If he improved any further, he would be at the level of Yujiro unleashing his "Oni-Kakei" technique!

But Baki, who had already activated "Oni-sei" (Demon Back), had become much more indifferent. He felt neither fear nor anger; his mind was entirely focused on how to defeat the formidable enemy before him.

The Lion King was indeed an incredibly powerful figure, but even the strongest lion...

Baki assumed a stance, lunging forward with his hands above his head in a bull-butting position—a stance conducive to charging.

"Ah, there it is!" The audience exclaimed in surprise. They seemed to see something like, uh, what is that? It looks like a dinosaur!

It was a Triceratops!

“Baki…” Retsu Kaioh gasped, “This is an incredibly impressive form of martial arts! But Triceratops Fist… I really don’t know how you came up with that.”

Baki was already an extremely powerful fighter, and he also possessed the ability of "imaginary practice," which meant that his mental strength was extraordinary and he could hypnotize himself. He imagined himself as a Triceratops, and with the mimicry of his body, the impact he could unleash was really close to that of a Triceratops—even though no one in the world had ever actually seen such a thing.

He will use this move to kill "The Lion King". Perhaps the lion is the king of beasts, but it is unlikely to gain an advantage when facing the ancient dinosaur behemoth!

"Oh my, kid, you struck a great pose. I can see that's three..." Shingoro Koyasu maintained this rhythm throughout the match, often getting attacked by Baki before he could finish a sentence.

"Boom!" Needless to say, Baki's charge was fast and fierce, and Koyasu's speed was not enough to dodge it, so they collided.

The experienced Koyasu positioned his arm in the path of Baki's charge, but Baki's charge was a one-shot deal, prioritizing power over speed. He didn't need to be predicted and didn't care about being predicted. Even though Koyasu hit him first, Baki still managed to throw his own punch while enduring Koyasu's attack...

After a loud bang, blood splattered, figures parted, and the audience screamed in terror.

As a result, Baki fell to the ground, and Koyasu broke his arm.

What a swift and brutal victory!

Baki originally intended to fight Koyasu to a draw, relying on the ferocity of his "Oni Back." Unfortunately, at the last moment, Baki's short stature and lack of evasion became apparent—he couldn't reach Koyasu's torso! Helpless, in an instant, Baki's only option was to smash his fists into Koyasu's arm joints and use the force of his impact to break Koyasu's arm.

Koyasu's arm did not deliver a straight punch, but rather a thrust forward with all five fingers together. His arm had undergone special training, and this thrust was Koyasu Shingoro's ultimate move. The damage was incredibly strong. Baki's chest was pierced, leaving a huge wound with massive bleeding, and he was almost in mortal danger!

"Ptooey—" Zi'an spat out the blood in his mouth, which was still the bruise from the fall earlier: "My move is called 'Pluto's Demon Spear.' Pluto is more powerful than your Triceratops, right?"

Author's Note: The next match is a no-brainer, it's Kanon vs. Kaiya~ It'll be over tomorrow, there will be another chapter in a bit, maybe a little later.

As for Koyasu's "Demon Gun," Master Kuroki, you're still a plagiarist (winking emoji). After all, it's a prequel by the same author, so the ideas are borrowed.

Section 655, Chapter 648: How many people can defeat Komada?

No one expected Shingoro Koyasu's unexpected intervention, and no one expected that what was supposed to be a friendly sparring match would turn into a fierce, bloody, and even life-or-death struggle involving the Hanma brothers.

Fortunately, Kouyou was also there and had been waiting on the sidelines. When he saw that Baki's chest had been pierced, he immediately jumped down to treat him. While stopping Baki's bleeding, Kouyou was secretly shocked: "What fierce penetrating power! Even with the toughness of the muscles behind Baki's 'Demon Back', it was almost pierced through! And... he held back."

That "Demon Spear of Hades" deliberately avoided Baki's heart, instead aiming straight for the center of his chest, minimizing the risk to his life.

"Shingoro Koyasu, what a terrifying man... Fortunately, he's not cruel." With this sigh from Kouyou, Baki's injuries were temporarily stabilized.

On the other side, the "terrible yet kind man" had already walked back to the "Kanon Team's" rest room, dragging his injured arm.

Despite his broken arm, Koyasu showed no signs of pain. Instead, he appeared relaxed and even had a smile on his face. He first greeted the samurai Wakatsuki: "Yo, Wakatsuki, thank you for giving me such an interesting battle."

Then he saw three familiar faces: Zong Longshen, Daimon Tohei, and Mabi Haku: "You little brats are here too~"

Finally, it was Hanon's turn: "You must be Ye Hanon~ Tsk tsk tsk, how can this delicate little girl be so powerful!"

Hanon's expression was very serious at this moment. She was shocked by Koyasu's fighting power. She respectfully clasped her hands and bowed to Koyasu Shingoro: "Hello, Uncle Koyasu, I am Hanon."

"Heh..." Zi'an pondered for a moment in front of Hua Yin, then suddenly shouted, "Take this!"

He suddenly attacked with his left hand, which was gripping his injured arm, his five fingers together and straight—a hand chop!

The incident happened so suddenly that no one expected Zian to launch a sudden and powerful attack, and the chop struck Hana's neck instantly.

Hanon was hit and her body swayed, but she only swayed and did not collapse.

And so Shingoro Koyasu's pursuit began—the slashing hand blade transformed into a straight thrust, the "Demon Spear of Hades" that had shattered Baki?

No, the "Demon Spear of Hades" isn't an attack that can be thrown casually. It requires Zi'an to gather his strength beforehand, achieving perfect harmony between mind and energy, akin to a perfect straight punch in karate. The hasty thrust he unleashed in that instant was at most just an ordinary "Demon Spear"!

It doesn't really matter whether it's "Demon Gun" or "Hades' Demon Gun," since it didn't hit the target anyway.

Hanon used "Unpredictable Transformation" to launch herself at lightning speed. By the time Zian straightened his arm and completed the thrust, Hanon had already retreated seven or eight meters away.

After this sudden change, the martial artists in the lounge finally reacted. Oni-Ohyama was the first to stand up: "What are you doing!" Then, Koucho, Murobuchi, Maki, Kaneda, Himuro... all the fighters in the room stood up and moved closer to Koyasu!
