Sheer Heart Attack

In the washroom.

Slap-

Jilan Jiyu cupped water in both hands and splashed his face several times in succession. He took a few ragged breaths, then looked at the handsome, blond teenager panting in the mirror. Seeing his nails growing longer and longer, Jilan Jiyu let out a bitter laugh.

"Why did I have to inherit your Stand of all things? Star Platinum, Crazy Diamond, even Hermit Purple, the most useless one—I could have accepted any of them. But why did I get your ability...?"

Naturally, the person in the mirror didn't speak. He was only talking to himself. After venting a little, Jilan Jiyu calmed down, picked up the watch, and fixed his eyes on the skull.

"No matter how much I regret it, I can't undo what's already happened. What I need to figure out now is how to use this watch-shaped bomb tank... Yoshikage Kira passed his perverted Quirk on to me, so I'd really be doing myself a disservice if I didn't master his ability."

Normally, once ordinary people had their Quirks identified at the age of four, they would naturally grasp the most basic way to use them. As they grew older, they became more and more proficient, until they could control their Quirks as readily as they moved a part of their own bodies.

When Jilan Jiyu was four, the doctor had identified his Quirk as a strange energy in his body. Much as he could clearly tell how much water was in his bladder, he could vaguely sense how much of this energy he had and knew how to discharge it.

After Jilan Jiyu used it and tested it repeatedly, a sense of déjà vu told him that his Quirk was the energy called "Hamon" from JoJo.

Then he sensed that another, different ability lay hidden inside him. After similar tests, he concluded that it was the ability of "Killer Queen," which could turn objects or people into bombs.

He had also wondered why his ability was incomplete, but had reached no conclusion. Even if it were a math problem, there were far too few conditions given to solve it.

But now, perhaps he had found a tiny piece of a huge puzzle: "Yoshikage Kira," "the indescribable thing," "All Might"...

The many people and things intricately connected to the anime JoJo's Bizarre Adventure from his original world would all serve as clues, allowing him to open the sealed door to the truth.

So first, how should he use—or rather, activate—this second ability, Sheer Heart Attack?

Jilan Jiyu tentatively pressed the skull and infused it with Hamon. The feedback he received was rather strange: the watch before him had both the characteristics of a living being and the properties of metal. The Hamon could be conducted into other objects and could briefly control the other party's consciousness.

That was merely the conclusion drawn from the feedback, however. In reality, Jilan Jiyu didn't sense any will within it.

Further experimentation.

Jilan Jiyu touched the skull again. This time, instead of infusing it with Hamon, he used the Quirk "Killer Queen" to turn the watch into a bomb.

Just as Jilan Jiyu had expected, the skull seemed to come to life. It turned its head up and down, back and forth, while making a "kuh-kuh kuh-" sound.

After keeping it up for a while, it seemed puzzled by its surroundings and fell silent for a second or two. Suddenly, the watch face split open, revealing the lower half it had hidden inside the watch: a lower body resembling tank treads.

It suddenly leaped out of the watch face. While airborne, it swiftly pulled its hands out of the gaps beneath the treads-bony claws like those of a simple robot—and struck a pose with its arms crossed!

"Are you my master? I am a derivative of the invincible Stand Killer Queen, a bomb tank that can pursue enemies without limit!"

Just as whenever Golden Iron Beast appeared, Jilan Jiyu could almost imagine sparks flying from its body as it finished transforming.

No, that wasn't what he should be commenting on. Jilan Jiyu hesitated as he watched the skull's jaws open and close incessantly.

"You can talk?"

"Hoo hoo hoo hoo-Master, I'm communicating with you telepathically! Other people can't hear what I'm saying!"

The skull continued shouting noisily inside Jilan Jiyu's head. "Master, do you have a target you want me to eliminate? I-I'll definitely blow them up until there isn't even ash left!"

So noisy...

Jilan Jiyu picked up the skull, remained silent for two seconds, then slammed it hard against the floor.

He suddenly fell quiet. When Jilan Jiyu picked him up off the floor, he seemed dazed by the sudden attack and said nothing. The skull swayed unsteadily, holding his head with his hands, and took quite a while to come to his senses.

"Master, what are you doing?! Why did you throw me down?!"

"Hmm... I just wanted to test your resistance to impact." Looking at its completely undamaged shell, Jilan Jiyu glossed over the real issue. "Looks like your body is pretty sturdy."

"Hahaha, of course!" The skull was instantly distracted and laughed wildly. "Back then, even Star Platinum's 'ora' didn't seriously damage me. How could a test like that possibly hurt me?"

"Wait, you remember what happened before?"

"This is the third time you've summoned me, Master. How could I forget?" it answered excitedly in response to Jilan Jiyu's question. "Although I failed the second time, you've now let me inhabit a watch, Master. Next time, I won't fail again!"

"The master you're talking about... who is he?"

This question was crucial. If it said Yoshikage Kira's name, Jilan would be able to infer what Kira was planning to do with him. He would just have to keep things from going in the direction Kira wanted... Even if its answer was someone else, it could still provide Jilan Jiyu with a clue of some significance.

"Why, you, of course—the wielder of Killer Queen!" it said frankly. "Although you've grown younger in appearance, your essence hasn't changed. I could recognize you at a glance!"

"Oh, I see. Go on." So this guy has no idea what happened and only remembers the times he was summoned... Come to think of it, it actually sees Yoshikage Kira's essence and mine as the same.

"My eyesight isn't very good, but I'll definitely chase an enemy until they die. Just leave any enemies you need dealt with to me!"

Jilan Jiyu understood. "In other words, you want me to let you out often, right?"

According to it, this was the third time it had come out. Apart from the time it fought Jotaro Kujo, the other time should have been when Jilan Jiyu tested its ability. After all, before encountering the protagonist's group, Yoshikage Kira had always believed he was the only person with an ability like this. He handled whatever he could himself and wouldn't use something so impractical.

So this guy's been stuck on the bench forever...

Watching it nod furiously, Jilan Jiyu continued, "You can give up on that idea right now. I don't have any enemies I absolutely need to hunt down and kill, so I probably won't have any use for you."

Although the League of Villains still posed a threat, that had little to do with him. After all, even if the sky fell, All Might would hold it up.

Jilan Jiyu's answer was like a bucket of cold water thrown over it. It hurriedly said, "Master, I don't have to blow people up! Whether it's spying, eavesdropping, or tracking, I can do it all!"

Seeing that Jilan Jiyu seemed tempted, he pressed his advantage. "Look, a meat shield as tough as me won't get smashed even if someone discovers me, and no one will trace me back to you. If you're willing, I can even make the other party disappear outright..."

Watching it strive to demonstrate its abilities, Jilan Jiyu thought of a prisoner toiling away in a cell and yearning for freedom, willing to do anything to achieve his goal...

"Can you manage not to kill anyone?"

To be honest, Jilan Jiyu felt a little sorry for it. As long as it could accept his rules, he didn't mind letting it stay outside.

"Master, forget killing people—I wouldn't even crush an ant!" the skull declared, saying something even he didn't believe himself.

Jilan Jiyu rolled his eyes. "All right, you can stay with me for now."
