Dragon Ball, simultaneously traversing countless worlds

"Extracurricular practice?" The students looked puzzled.

"You've all been training for a week, and your skills have improved significantly. It's time for you to get some real combat experience."

Yusuke asked curiously, "In actual combat, who is the enemy?"

"Aliens," Luo Yan replied simply.

"alien?!"

The group of students looked at each other in bewilderment, then became excited again after a short while.

"That's so cool! I've never seen an alien before. I wonder if aliens are good or bad?"

No one in Gotham City questions the existence of aliens. They have monsters, demons, and Titans, so isn't it normal for aliens to exist?

"The thought of fighting aliens is exciting!"

Some students were excited, while others remained calm.

"Principal, why are we fighting aliens? Are they hostile to humans?"

Luo Yan clapped his hands, and a transparent panel appeared in the classroom: "You students are really out of touch with society. Don't you watch TV news or read newspapers?"

"Don't you guys know about the Shibuya incident a while ago?"

Someone spoke up: "Principal, are you referring to the incident where the men in black fought the monster in Shibuya? Were those tentacled creatures aliens?"

"That's right, those are a type of alien hidden in human society. Those who have read the Shibuya incident reports should know this."

In that battle, hundreds of Self-Defense Force members and civilians perished at the hands of the monster, which even boasted of wiping out the entire city's population. The aliens' contempt and hostility towards humanity were unmistakable; they were, after all, humanity's enemy.

The battle between the Men in Black and the Oni Stars in Shibuya is the preceding chapter of the Gantz Hyakki Yagyō arc.

It was also during the Demon Star arc that the black sphere stopped blocking the vision of ordinary people and stopped concealing the battle process of the men in black, and began to be openly displayed to the world.

"Oh my god, that's real! I thought it was just movie special effects!"

"Principal, who are those men in black fighting the aliens? Are they from a government department? Or are they aliens themselves?"

"No, they are human beings, a private armed force."

Luo Yan brought up another screen and said, "This is Hanscat's news, reporting on a black ball worship group."

The news footage showed a gigantic black sphere placed in a football field, with countless civilians kneeling around it, chanting in unison as if they were worshipping a deity.

"The black ball in this news is a weapon terminal produced by a wealthy individual from Hanscat."

"The tycoon scattered many small black spheres in various countries and cities around the world, using the black spheres to plant bombs in the brains of civilians, thereby controlling them to wear black enhanced suits to fight aliens."

"The men in black you see fighting aliens are actually just a group of ordinary people who have not received military training."

"Damn it, they actually planted a bomb in someone's head and forced them to fight. I don't think this rich man is a good person at all!" Yusuke said angrily.

The students discussed the wealthy man's behavior, the man in black's fate, and the aliens' cruelty and brutality with righteous indignation.

Seeing the students' enthusiastic atmosphere, Luo Yan asked, "So, how many of you are willing to participate in a real-world battle to kill aliens? Please raise your hands."

In an instant, at least half of the students in the class raised their hands.

Chapter 280 Dotonbori

Of the 100 people, more than 50 are willing to fight aliens, which is a decent percentage.

Luo Yan didn't care what the psychology and thoughts of those who were unwilling to fight aliens were, nor did he bother to guess or persuade them.

"Very good. All of you who raised your hands will receive a shelter unit. This unit can help you escape from combat if you are seriously injured."

The so-called shelter unit is just a weakened version of the bio-armor.

The shelter unit can record all of the students' genetic information and, in the event of a student suffering a severe injury or even having their brain blown out, can help repair their body and then transport them back to the school's infirmary.

The shelter unit itself does not carry weapons such as particle cannons or high-frequency swords, and it cannot even control gravity to fly.

This battle against aliens is a test for the students. If they were given bio-armored armor with weapons, the battle would be less interesting.

The destructive power of the Guyver Armor is unmatched by the Black Coat from Gantz. Once the full version of the Guyver Armor is worn, dealing with those four-eyed giants is like killing ants, let alone dealing with Nurarihyon, the big boss of the Hyakki Yagyō arc.

In the evening, after the students were all ready to go, Luo Yan glanced at his watch and said, "Alright, it's about time. I'll take you all to the battlefield in Osaka now."

Luo Yan pressed a button on his watch, and instantly a loud, booming tunnel appeared in the classroom.

This is the Apokolips teleportation technology obtained from the black technology system, which can open teleportation channels at will within a range of millions of light-years to transport people and goods.

Luo Yan led the students through the tunnel of explosions, and the next second they arrived at Dotonbori in Osaka.

Dotonbori is a canal located in Osaka City, Osaka Prefecture, Japan, and is known for its nearby theaters, shops, and entertainment venues.

Dotonbori connects with the Kizu River and the Higashiyokobori River, and is about 2.5 kilometers long. The story of the Hyakki Yagyō (Night Parade of One Hundred Demons) takes place along the banks of this canal.

Dotonbori, which should be bustling with activity and teeming with people, was devoid of its usual vibrant atmosphere.

After passing through the tunnel filled with explosions, Luo Yan and his group of students arrived at the Dotonbori area, only to find buildings in ruins and a bloody battlefield littered with corpses.

As soon as they finished teleporting, they were immediately confronted by a group of men in black who pointed guns at them.

Who are you?

As the students finished their teleportation, a group of men in black nervously pointed strange firearms at Luo Yan and the students.

"Huh? I just randomly picked a teleportation point on the edge of the canal, and it just so happened that I ran into the main characters?" Luo Yan thought to himself.

The person pointing a gun at Luo Yan and the others is Kato Masaru, the protagonist of the movie version of "Gantz: O". He is an indecisive, good-natured man, a master of slow and steady marksmanship, and a guy who won't fight the boss until the girls die.

Behind Kato Masaru are the well-known model Shimohira Reika, the old man Suzuki Ryoichi who looks like Inuyashiki Ichiro but only plays minor roles, and an ordinary junior high school student Nishi Joichiro.

The movie's main team consists of only four people, which is much less powerful than the main team in the comics. The superpowered master and apprentice, the two vampires, and the martial arts master are not in the movie's plot.

Luo Yan didn't even bother to look at the four people, ignoring the movie's main characters even with a gun pointed at him.

If the manga protagonist, Kei Kurono, were here, he might have tried to talk to him, but he had absolutely no desire to speak to someone as useless as Masaru Kato.

"It stinks and smells so bad! Is this Dotonbori in Osaka? Why is the environment so terrible?"

The students behind Luo Yan pinched their noses and complained.

"Wow, so many dead bodies around here, has the battle already begun?"

Da da da!

At the end of the narrow street, the sound of wooden clogs tapping on the stone slabs could be heard.

A woman dressed in a kimono, with no facial features but only a set of black teeth, stumbled towards the crowd.

"Is that an alien disguised as a monster? It looks like the legendary 'Black Tooth Woman'! But I can't sense any spiritual power, so it's not a real monster."

Yusuke, eager to try, raised his hand, gathering spiritual energy at his fingertips, and walked towards the Black-Toothed Woman.

"Hey, stop right there! You're still a student, aren't you? Come back here! That monster is not someone you can handle!" Kato Masaru said anxiously behind Yusuke.

Yusuke glanced back at him and said, "Aren't you a high school student too? You underestimate me? This kind of monster is nothing to me."

On Saturday and Sunday, Yusuke went to Genkai's dojo for further training and even defeated a demon named Rando, further increasing his strength.

Moreover, Yusuke also learned chakra. The combination of chakra and spiritual power is almost like Sage Chakra, greatly increasing its power.

"Watch closely, I'm going to take care of it right now. Fire a spirit ball with one-tenth of its power!"

Yusuke used his hand as a gun and aimed it at the Black-Toothed Woman's heart.

In an instant, a spirit ball made entirely of spiritual energy pierced through the Black-Toothed Woman's heart.

The ugly monster swayed a few times, then collapsed at Yusuke's feet, and remained motionless.

Swift and decisive, Yusuke killed 'Black Tooth Woman' without any hesitation.

"Wow...so powerful!" The main characters were dumbfounded.

"Who exactly are you people? And what was the technique you used to defeat that monster?" Kato Masaru asked, recovering from his shock.

"I'm a student at Ishiyama High School. This is my special skill—Spirit Ball. How about that? Not bad, right?"

“Ishiyama High School, I think I’ve heard of that high school. It’s said to have started training delinquents a week ago…” Kato Masaru looked at Luo Yan and the fifty-odd high school students behind him and said, “What is your purpose in being here? Is it also to eliminate these monsters?”

Luo Yan ignored Kato Masaru and Yusuke replied, "This is a practical exercise at the school. You could treat us like we're here specifically to eliminate these monsters."

"That's great! We share the same goal: to eliminate these monsters. Please come with us, and I will protect you."

Yusuke looked at him suspiciously: "You were scared by the Black-Toothed Woman and took a step back, weren't you? Someone like you is planning to protect us? That's hilarious!"

Kato Masaru's face flushed slightly. He didn't consider whether he was a match for Yusuke at all, and just kept saying things like he was going to protect Yusuke.

Someone as weak as him is lucky if he doesn't drag Yusuke down, let alone protect him.

Luo Yan sensed that hundreds of alien monsters had appeared around Dotonbori, so he stopped Yusuke and Kato Masaru from talking.

He waved his hand and said to the group of students behind him, "Alright, we have arrived at the location for the practical training exercise. Now you can start trying to defeat those monsters or help the local civilians take refuge."

Your facial expressions have had their frequencies altered by the metal spheres on your bodies. Unless you actively reveal your origins and names, no one else will remember what you look like.

The fifty-odd students dispersed without hesitation and went into the streets on both sides of the canal to slay the alien monsters.

They had witnessed the civilian casualties in Dotonbori, and Luo Yan believed that none of his students would show any mercy.

Just as Yusuke was about to leave, Kato Katsuto said, "Wait, please, come with us."

Yusuke scratched his head, hesitating slightly: "This..."

The beautiful part-time model and actress, Shimohira Reika, also came over and said, "Thank you for your help, please come with us!"

Upon seeing a mature and beautiful older sister also asking him for help, Yusuke shamefully succumbed to her charms and joined the main characters' group.

Luo Yan scoffed disdainfully and disappeared into the shadows.

He didn't need to participate in the battle; his task was simply to remain hidden and observe his students' fighting. He didn't intend to interfere with Yusuke's choices.

Chapter 281 The Night Parade of One Hundred Demons

After Luo Yan's students scattered, they discovered that the situation in Dotonbori was far more brutal than they had imagined.

When those foul-smelling alien monsters crawled ashore from the canal, there were still many civilians on both sides of the shopping streets in Dotonbori.

The civilians who did not have time to evacuate suffered heavy casualties under the monster's brutal slaughter, with corpses everywhere that had been cut in half at the waist, had their heads crushed, or had been split in two.
