This is My Chikara (Power)?

Evil Ayanokoji Kiyotaka, I, Baiye Ying, shall personally see to your expulsion!

Why did Ying suddenly make such a firm resolution? That goes back to the moment he arrived at Kouiku...

"Damn you, Tsukishiro! Why wouldn't you let me take the bus! You actually dropped me off at a crossroads and made me walk the rest of the way. I thought it was close, but after checking the road sign, I realized it was ten kilometers! You made a high school student with no money and nothing but a personal file walk for an hour." At the main gate of the Tokyo Metropolitan Advanced Nurturing High School, a grumbling young man with black hair walked inside. It was none other than our own Ying.

He took a deep breath, steadying his emotions. "It's fine. I'm inside the school now, and that old geezer can't reach me anymore. At least for the first year, anyway... Walking here not only helped me get used to this grown-up body, but I also got to enjoy the scenery of Japan. I should be happy, yes, happy is good, hahahaha..."

Forcing himself to change his mood, Ying began to examine the campus environment of Kouiku. His first reaction was: it's huge! It felt less like a school and more like a miniature town. The wide roads were lined with greenery, a massive shopping mall was visible at the end of the path, and further along, one could spot an artificial lake where water jets erupted from time to time. Cherry blossom trees were planted beside the school buildings and dormitories, and in this April season, the branches were already covered in pale pink flowers.

After wandering around the Kouiku scenery for a while, the anger in Ying's heart had long since dissipated, and he began to look forward to his future campus life.

Stepping into the classroom of Class D, Ying immediately noticed the conspicuous figure in the corner.

I'll just pretend I didn't see him. After all, who in their right mind would want to go against the protagonist? I've already lived ten years less than I should have; every second from here on out is precious!

After silently deciding this in his heart, Ying began to look for his seat, but he couldn't find it anywhere. Could it be near Ayanokoji!?

Ying couldn't help but feel nervous. I'm not an assassin, I'm not an assassin... I have no skills, so how am I supposed to win? I'm just an ordinary student!

Suddenly, a sharp pain shot through Ying's skull. Just like when he had suddenly recalled five years of memories, he was now suddenly proficient in martial arts, including but not limited to karate, judo, and taekwondo.

???

Ying seemed to realize something. Could it be that he actually possessed the power of "word-manifestation"!?

Even with just raw martial prowess, I can't beat Ayanokoji. I need heaven-defying academic ability, otherwise, I'd be sold out by him and still be helping him count the money.

Following that, he became proficient in advanced mathematics, quantum mechanics, organic chemistry, and other subjects. At the very least, there would be nothing left for him to learn during these three years at Kouiku.

I've lived ten years less, so I must cherish my time and enjoy these three years of campus li...

Ten years of time suddenly appeared in Ying's memory. His brain was... trembling! It seems that for those ten years, Ying had followed his own principles and held back, only ever achieving barely passing grades until Tsukishiro came to find him.

Hehehe, hahahahaha! Ying covered his right eye with his right hand and let out a dark laugh. Atarashii chikara da, warukunai. (New power, not bad at all.)

With abilities like these, why the hell would I want to be a White Room assassin? Shouldn't I be enjoying a life of luxury instead?

[Host's intent detected as inconsistent with this system. Stripping away karate, judo...]

'Wait a minute, what is this thing?'

[White Room Assassin System. Successfully bound since the host's transmigration. Officially activated upon receiving an assassin mission and making contact with the target. All beginner rewards have been completed, as follows: deletion of ten years of time, martial prowess not inferior to Ayanokoji Kiyotaka, academic ability not inferior to Ayanokoji Kiyotaka, and the deleted ten years of memories. Because the host is violating the mission's intent, the beginner rewards are now being reclaimed...]

'Ayanokoji Kiyotaka, I, Baiye Ying, as long as I am at Kouiku for a single day, you won't have a peaceful campus life!'

[I don't believe you.]

!!!

'No, man. I didn't even hold it against you for lurking for so long, and you didn't even give me a heads-up about these beginner rewards. Does this mean you were just fulfilling my four wishes?'

[That is exactly the case.]

'Damn it!'

Ying was on the verge of tears. Weren't the first and fourth wishes basically the same as having nothing at all?

[Reclaiming...]

!

But he still had to fight for the two useful wishes.

'Haven't I already decided to get Ayanokoji expelled? Why is it still reclaiming?'

[No such intent detected in the host's heart. Please provide actual actions as proof.]

Ying: ...You really hit the nail on the head...

[Reclaiming...]

'Is it really that urgent!?'

Doesn't this mean Ying has to go back ten years and suffer through it all again? Now that he had the memories, even Ying, who cherished his life, didn't want to go through that again.

There was no time to hesitate. Ying walked quickly to Ayanokoji and locked eyes with him.

Ayanokoji: ...

Ying: ...

"Um... may I ask if this student needs something?" Ayanokoji finally lost the staring contest and couldn't help but ask. He had noticed Ying earlier; he watched as Ying wandered around, suddenly stopping in one spot to make wild expressions, twitching his body, and covering his eye while giggling. He had even started to wonder what kind of method a lunatic would use to get into Kouiku. He hadn't expected Ying to suddenly walk over and stare at him blankly, which made his skin crawl.

"Wait, let me think." Ying held his forehead with one hand, looking as if he were deep in thought. How could he express, in a subtle way, that he was being forced to get Ayanokoji expelled, even though he had no such intention himself?

If anyone heard this thought, they would surely say, "How are you supposed to express that subtly in just a few words, you idiot?"

"Student, do you... want to be expelled?"

"I do not."

"Then can you be expelled?"

"Why would I want to be expelled?"

"Then, sorry to bother you, Kano."

Ying strode away after hearing the words "retrieval retracted," chuckling to himself from time to time as if celebrating his own victory.

Left behind was Ayanokoji, who appeared calm on the surface but was utterly bewildered on the inside. What was this guy talking about? First, he ruled out the possibility of him being an assassin from the White Room, as the educational standards of the White Room could never produce a student like this. It seemed he was just an ordinary, albeit very eccentric, classmate. Wait, why did he keep wandering around until he walked out? Wasn't class about to start?

Ying could only lament his failure; how could he have forgotten to check the class information on his admission letter? He was clearly a student in Class B, yet he had subconsciously gone to Class D and wandered around inside for ages. If anyone discovered that he had gone to the wrong class in a school with only four classes, he would likely be hung on the school wall and mocked until graduation. Now, he could only hope that the people in Class D wouldn't notice someone as unremarkable as him.

Ike: "Yamauchi, let me tell you, I think there's an idiot in our class."

Yamauchi: "Huh? Where?"

Ike: "I saw someone with black hair wandering around the classroom, making weird laughing sounds, pulling bizarre expressions, and staring at people constantly. He just left. Why would this school have someone like that?"

Yamauchi: "Looks like we'll have to avoid that guy in class from now on."

Ike and Yamauchi nodded in unison.
