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

"Thump—thud." The first sound was the dull thud of the boxing gloves hitting the sandbag, followed by the sound of the sandbag flying out and hitting the wall.

That's right, this punch sent the sandbag flying. Hibiki Sakura's punch was terrifyingly powerful!

"Hey! This power is excessive!" Everyone was stunned.

This isn't the punching power of a high school girl; it's practically inhuman strength. Calling her "One-Punch Man" wouldn't be an exaggeration.

The Uehara sisters were stunned. After a long silence, Nana Uehara finally managed to squeeze out a few words: "Sakura... First of all, let's aim for the world championship..."

"Huh? What do you mean by 'firstly'?!" It seems that the only one who wasn't stunned was Hibiki herself; she still had the energy to complain.

Kanon was also stunned by Hibiki's performance. She even began to suspect that Hibiki was also a time traveler with similar abilities to herself. Otherwise, how could she explain such extraordinary punching power? Was it because it was a comedy manga?

However, although Hibiki's performance was amazing, Kanon was only surprised rather than shocked, because she vaguely felt that her punching power was probably no less than Hibiki's, and might even be stronger.

After the shock of Hibiki, the people at Glory Boxing Gym had no expectations for Kanon's training. After watching One-Punch Man's performance, watching such a thin girl like Kanon box was really boring!

"Then, Kanon-kun, why don't you give it a try?"

Before Kanon could make her move, Uehara Nana regained her composure a bit more and then gave a further explanation of boxing: "You can't achieve the same effect as Sakura just by relying on wrist strength. Her posture is excellent, her lower body is stable, and her overall coordination is superb. She definitely has the potential to be a world champion!"

"Ah—it doesn't feel real at all. World champion or anything like that, forget it." Hibiki is just a high school girl in the surface world and isn't very interested in boxing.

It was Kanon who truly learned something: "I see, you need to coordinate your whole body."

Hanon's eyes sharpened: "Then let's see how strong my full-force attack is!"

Since being transported to the new world and discovering that she could freely control her muscles, Kanon has only focused on training the precision, strength, and endurance of her muscles, and has never tried to unleash an attack that fully utilizes her potential. Last time, when she beat up the gang leader at Tsurumine Academy, she went all out, and the effect was outstanding, but at that time Kanon had just recovered from her injuries and had not trained, so her condition was completely different from her current state.

Conversely, if Hanon, a complete novice, could knock out a strong delinquent with a single punch, then after training for a period of time, to what extent has her talent guided her punching power?

Even Kanon herself was curious about the answer, and now it's time to reveal it!

When Hibiki appeared, everyone made their way out, so this chapter won't describe Kanon's fighting power. Actually, she will in the next chapter as well...

However, in the next chapter, Kanon will master her "ultimate technique," significantly increasing her strength and making her victory in the Kengan Tournament possible. Of course, she still has a long way to go to reach the level to defeat Kiba, but the author promises that Kanon will definitely defeat Kiba within five million words, lol.

Section 17, Chapter 17: Kanon's Deadly Move, the Tiger's Cry

Hanon took a few steps back, then rushed forward, throwing a punch that struck the sandbag squarely with her arm…

Just like with the sound, the result stunned everyone; the sandbag died a terrible death—not really.

The sandbag was perfectly fine, yet the exceptionally talented Kanon, after nearly half a month of training, couldn't even make the sandbag sway with her full-force attack?

The scene was quiet for a moment, until Uehara Nana couldn't help but burst out laughing: "Hehe, Hanane, you didn't calculate the distance properly during your run-up. Your arm was already straight when your fist hit the sandbag, so of course it wouldn't have any effect! The essence of boxing lies in the rotational force of the whole body, especially the waist, and the spring-like force provided by the bent muscles and joints~"

"Haha, Kanon is so cute." "What an interesting woman." "Being cute is a talent in some ways~" "It's okay, how about we try again?" The boxers watching also offered kind smiles and words of comfort.

In the relaxed atmosphere, Hanon didn't feel embarrassed, but rather seemed thoughtful.

"The ejective force of muscles and joints!"

Returning to the Takakaze family home with heavy thoughts on her mind, Kanon immediately asked Butler Ito to set up a boxing practice room. The next day, Kanon went into seclusion in this secret room, not allowing anyone to enter, and even having her lunch delivered to her door.

Uehara Nana's unintentional explanation allowed Kanon to vaguely grasp the secret to becoming stronger!

Since the power of boxing comes from the ejection force of bending muscles and joints, could Hanon, with her incredibly precise control over muscles, develop her own "ultimate move" from this?

"Bang!" Hanon stood in front of a sandbag and suddenly threw a punch. The sandbag was hit hard, twisted and snapped its rope, and flew out and crashed into the wall.

This is Kanon's full-force punch so far. Judging by the effect alone, it is the same as Hibiki Sakura's punch. However, given the Takakaze family's wealth, the material of the slings they prepared is definitely better than that of the Glory Boxing Gym. Furthermore, the speed at which Kanon knocked the sandbag away was also faster. Therefore, Kanon's punching power is slightly stronger than Hibiki's. If she had delivered this punch last night, I believe the people at the Glory Boxing Gym would have been stunned again.

However, Kanon was clearly not satisfied with this result: "This is my current level. It looks okay, but this striking power is still quite far behind that of the Fang of Destroyer, Kana. Besides, I don't have his level of skill... If I were to actually go into boxing matches, I would need to become stronger."

It has to be said that Kanon witnessed the peak level of Kengan from her first experience with the tournament. Using Metsudo no Kiba as her hypothetical opponent put immense pressure on Kanon, but this pressure also drove her to improve rapidly.

With her eyes closed, Hanon, with a seriousness she had never shown in her two lifetimes, sensed and manipulated her muscles inch by inch.

"What if I compress the muscles in my arm? Like a spring, when a spring is compressed to its limit and then released in one breath, it will generate an unparalleled rebound force. This is equivalent to concentrating the dispersed force into a single point, so the punch I throw will definitely be stronger!"

Silently walking to another sandbag, Hanon took a few deep breaths and threw another punch.

"Bang—crash."

The sandbag didn't fly out; it stayed in place. Did Kanon's attack have no effect?

No, it did have an effect, and a significant one at that. The sandbag didn't fly away; it exploded immediately after taking the punch, sending sand flying everywhere.

Now we can say, the sandbag died a terrible death...

"Cough, cough, cough." Hanon coughed incessantly, and sand got into her eyes, so she had to sit down and rub them. But as the sand gradually settled, Hanon's cough turned into soft laughter.

"Ah, very good, the method of compressing muscles is effective!"

And so, Hanon practiced all day in the "secret room" of Takakaze's house, and only went back to her room to rest happily late at night.

"Miss is finally out. Let's go in and tidy up." The two maids on night duty had been instructed by the old butler to clean the room overnight so that it would be ready for use when Hana came back the next day.

"Achoo~" The maid, exhausted from waiting until late at night, said, "I wonder what Miss Hanon is doing in there, keeping her up so late."

"I heard she's practicing martial arts. Miss Kanon has recently become very interested in fighting and killing."

"It's surprising that a girl likes these things, Miss Kanon is really something else!"

"Who knows? Rich girls are just eccentric. After all, they come from wealthy families and can do whatever they want as long as they're interested."

"That's true, maybe this interest will shift to something else in a couple of days..."

Two maids walked into the practice room talking, and then they froze.

The dozen or so sandbags that were originally hanging in the practice room all exploded, scattering yellow sand all over the ground.

The dummies used for practice were all in terrible condition; some had their upper bodies torn to pieces, some had their heads exploded, and some had lost a leg.

There were also two wooden stakes, each about the height of a person, with all the protruding branches broken off, leaving only two bare trunks.

Even a large section of one wall in the practice room had been peeled off—the walls of the Eagle Wind family's house are made of concrete!

"Oh no! What's going on here? Has this place been ravaged by monsters?"

With only two maids, it was naturally impossible to restore the practice room that night, and Kanon did not practice again the next day.

Firstly, while muscle compression is incredibly powerful, it also puts a heavy burden on the body, so Kanon needs to rest properly.

Secondly, Hanon has already mastered the way to exert force and is aware of the power of this move, so she no longer needs to practice so fervently.

Thirdly, the commotion this time was too great. The maids' accounts reached Ito, who then passed them on to Takakaze Kirito. Faced with repeated questioning from the old butler and her uncle, Kanon just laughed it off and said that she was "doing an experiment." As for the content of the experiment, she insisted on not saying. Seeing that she was not injured, the two elders could only tell her to "be careful" and then stopped asking questions. Although they didn't ask openly, they were keeping an eye on Kanon. Kanon had to behave herself for a few days no matter what.

Mystery breeds speculation, speculation breeds rumors, and before anyone knew it, the news that "Miss Hana of the Takakaze family is a dangerous bomb maniac" spread like wildfire among the wealthy young ladies.

But Kanon didn't have time to pay attention to any of that.

"I've really gotten stronger!" Lying in bed, Hanon was overjoyed. "Maybe I can actually join the Punchman tournament someday! Now I need to think of a cool name for this move~"

Unbeknownst to Kanon, some Kengan fighters had already mastered the same technique.

Known as "Tiger," Wakatsuki boasts a record of 300 wins and 2 losses in the Kengan tournament, making him the fighter with the most wins in history and a superhuman standing at the pinnacle of the world. The one who inflicted Wakatsuki's first defeat was none other than the fifth generation Metsudo's Fang, Kano Akagi.

After suffering a crushing defeat to Gana, Wakatsuki began a new round of training. The "hidden finishing move" that he mastered after eight years of hard work is the same as Kanon's, which involves gathering his muscles and then unleashing an attack with superhuman strength.

Wakatsuki named it: Core Burst!

Fortunately, Kanon and Wakatsuki didn't know each other. Otherwise, when Wakatsuki discovered that Kanon had mastered the skill she had painstakingly practiced for many years in just one night, even more skillfully than Wakatsuki, the "fierce tiger" would have cried!

The difference between people might not be that big, but the difference between people who have cheat codes...

This is the second chapter today. Kanon's power-up has been upgraded! We'll probably show it off next, but choosing the right opponent is a problem. The third chapter will be released a little later; the author needs to think about it…

Section 18, Chapter 18: A Master of Lackey

"Hey, Kanon, you've already finished practicing?"

At Mr. Shirogane's gym, Hibiki Sakura, Akemi Kanadein, and Ayaka Uehara, who had recently started working out there, had just stepped into the practice area, while our protagonist, Hanane Hagiwara, had finished her day's workout and was about to take a shower.

Hanon greeted her three friends warmly, "Yeah, I haven't had much to do lately, so I've been hanging out at Mr. Shirogane." Hanon hasn't enrolled in a Japanese university yet, making her a typical working woman with plenty of free time, so she naturally leaves earlier than the trio who come to the gym after school.

"Wow, you don't have to go to school? I'm so envious!" Hibiki exclaimed.

Ayaka, who was standing to the side, had a keen eye for detail. She noticed the changes in Kanon: "I say, Kanon, you seem to have grown taller recently, and you've become stronger too."

"Huh? Really? I didn't even notice." Hanon was a little surprised.

"That's right. For teenagers in puberty, moderate exercise helps with physical development, and muscles will expand after working out, making the whole person look stronger." Coach Jiexiong also came over at some point and gave another "muscle-building lesson" on the spot. Of course, to match the lesson, Jiexiong's signature shirt-ripping move was also indispensable.

Kanon couldn't help but complain, "Maiyuu, your family must be very rich. Judging from how often you tear off your clothes, your annual clothing expenses must be considerable."

"Kanon, when did you become so familiar with Coach Machi?" Hibiki was a little surprised. At first, she and Akemi were quite enthusiastic towards Machi, but Kanon's attitude was very indifferent. Unexpectedly, after more than half a month, Kanon and Machi had become "good buddies".

Well, Kanon's been spending a lot of time at the gym lately, so they naturally got to know each other. And Hibiki's perception was right; Kanon is a man at heart. Over time, he and Machio naturally developed a brotherly bond of mutual respect...

Actually, Kanon's situation with Mr. Shirogane was rather unfortunate. As the saying goes, "To a man with a hammer, everything looks like a nail." Ever since she mastered the "Exploding Core" technique, her interest in fighting, sports, and fitness has skyrocketed. She's even always itching to stand up for someone and pick a fight. Unfortunately, there's hardly any danger in the young lady's social circle. Kanon's life is very peaceful; there's simply no fight to be had.

Kanon had even planned to meet up with Mieko next weekend at Tsurumine Academy to "get revenge" on those delinquents from District D.

"By the way, I'm planning to go check out that 'invitation' later. Zhu Mei, do you want to come with me?" Hanon said to Zhu Mei.

Zhu Mei shook her head: "Forget it, I don't get along with the people who organized that 'party,' they... are a bit strange."

"Oh? I'm new here and don't know anything... But since I've already agreed, I'll go and see for myself." Hanon was surprised, but still decided to keep her promise.

"Hey, Akemi, what kind of party were you and Kanon talking about? It sounds pretty dangerous," Hibiki asked.

Zhu Mei smiled and said, "Actually, it's nothing. Rich kids often hold all sorts of private parties. It's just that this family always does something new and exciting."

Hibiki scratched his head a little: "Strange thing? What could it be? Rich girls are really unpredictable..."

……

In another mansion on the outskirts of Tokyo, a group of wealthy young men were gathered in the backyard, holding wine glasses and snacks, forming a small circle.
