Zenatori is standing in the middle of Akari's room and says,

"So what is a delimited strike?"

Akari lay on her bed and thought for a few seconds,

"Delimited and Absolute are two types of Isotonic infused strikes. The Delimited Strike is pretty hard to land and requires near-perfect timing while fighting someone. You're pretty much in maximum concentration mode when you land a delimited strike. Once you land the first, the second becomes easier to land and chain. Delimited strikes temporarily disrupt someone's isotonic force, which is the definition of striking a nerve. Since automorphs don't have isotonic force, they're useless against them. Absolute strikes, on the other hand, are nigh impossible and are pure luck. Tsuyo Hayoku himself has never landed an absolute strike before. They are pretty much game-ending strikes and not only temporarily disrupt someone's isotonic force, but since you're exerting so much isotonic force onto one point, they pretty much can one-shot an average syneji artist. There have been very few recorded in the entirety of history, with around thirty in the past millennium. Absolute strikes can only be achieved during an adrenaline rush while also focusing. Absolute strikes also require an incantation as well."

"What is it?"

"Grand Uncertainty: Absolute Strike."

"How do you know so much about this stuff?"

"Well, I was kinda raised like this. The Akari bloodline has existed for centuries. During the Okina generation, Yukashika killed almost everyone in that generation of my family, almost ending the bloodline. Luckily, 3 out of the 10 members survived and continued it. If Yukashika never attacked us, I would most likely be a lot stronger if I were still born right now."

"How?"

"The Okina generation was the peak of syneji artistry; everyone during that period had massive pools of isotonic force. If they could pass it on to me, I would have more than what I have now because Isotonic force is mostly a genetic trait, but it is possible some could be passed down to me."

"Interesting."

"You know, when you become a third year, you are officially considered a syneji artist, and you can earn money from this stuff. B-Divisions can earn up to a million yen a month. But like S-Divisions can get paid up to two million a month. I can only wonder how much Divine Masters get paid."

"That's quite the amount. Hayoku's probably a millionaire then."

"I mean, you're literally risking your life to protect humanity."

Zenatori thought to himself,

Zenatori begins walking to Mashaka's class and is intercepted by Iwasaki.

"Yo, bro. You didn't forget me, did you?"

"No, how could I? It's literally only been a day."

"Ah, I knew you really are my bro. But I know you like to talk to your girl in this hall, so I'll let you be."

Zenatori irritatedly thought,

"Sakatoro!" Yachi said, running through the hall to Zenatori.

"Oh, it seems I'm interrupting something. I'll be on my way, bro."

"Hey, Sakatoro, is that your friend?"

"I'd say he's more of some classmate I so happen to know the name of."

"Really, now?" 

Zenatori slides the classroom door open, and Yachi and he enter the classroom. Zenatori takes a seat and places his hand on his chin, then sighs. Akari walks into the room a few moments later, and Zenatori says to her,

"I won't be able to do training today."

"Very well."

"That sounded awfully subservient. Are you just not gonna question it?"

"What would be the point in that?"

"Fair."

Class ended, and Zenatori walked out of class. He suddenly stopped by the shy girl with whom Zenatori had actually made eye contact. She had a petite figure, was somewhat shy, and had brown hair.

Zenatori thought to himself,

"Um, well, do you still want to go to the library?"

"Sure, Itsuki."

Zenatori instantly thought,
