As September was over it was now October, time flew by as Y/N and the rest of his class was focus with their studies. Todoroki and Bakugo have been doing great in their remedial class in their Provisional License class.

During those times, the students who were present during the work study, along with All Might and Aizawa to attend Nighteye's funeral. It was a mutual decision for the agencies and the school that the work study would be postpone for the time being.

As Ectoplasm wrote the equation on the board, the H/C haired teen kept on looking at it as he sighed.

Y/N: I hate Math... but, I can't really complain anything I hate about it when Sir Ectoplasm is here... he really likes this subject way too much...

He thought as Ectoplasm finished writing on the bored in which, Y/N just drifted his eyes on the window as a red rabbit passed by.

Y/N: That... wasn't normal... was it?

He thought as he was lost for words as he tried to focus up on his studies for the meantime, trying to forget about what he just saw.

As the class was over, Y/N fixed up his things as he was ready to head out, trying to clear his head for once as he walked out of the room. He went to the cafeteria as he grabbed some food and went to his friends table.

Jack: Looks like you got something on your mind.

Y/N: Do I look like the obvious one?

Senkai: Y/N, we have been friends for a while now. Yes, you are looking obvious.

He said as Y/N deadpanned as Senkai eats his food as the H/C haired teen looked at them.

Y/N: Just tired from class, nothing new there. So, what happened? How did your class reacted to the news?

He asked as he was pertaining to the events that had happened with the Shie Hassaikai.

Jack: Well, they were worried sick and gave me some special treatment.

Senkai: Actually, same here.

Jack: Also, they blame you for leaving us, but I explained that it was our own decision to let you go.

Y/N: That still makes me the bad guy in your stories.

Senkai: Don't worry, you'll grow on to it.

Y/N: Gee, thanks a lot...

Y/N groaned as he tried to eat, pushing the thoughts away of how he became the villain that left his friends to fight Aku.

Night came as Y/N was working on his homework, he felt that he had missed being a student for once as he is actually making his homework.

Y/N: I missed this.

He said as he heard some shuffling noises from outside as he was curious about it, as he decided to walk towards his window to look at what was going on.

As he was about to open his window, a scream was heard as he didn't hesitate anymore.

Y/N: Build!

He said as the driver appeared on his waist as an orange gun appeared on his hand kind of a mini gatling gun, as he opens his window and aims down, only to see no one was there.

Y/N: Just what is happening here?

He said as he looked down and to his surprise, there was something written outside Midoriya's room.

Y/N: "I know."

He read as he squinted his eyes a little bit as he saw that the writing was something... extra.

Y/N: And is that... cheese?!

Morning came as Midnight was teaching the students for today, Y/N kept on thinking on what he had saw from last night as he rubs both of his eyes.

Y/N: I am not gonna look at cheese the same way like last night...

He thought as he kept his focus on the lesson. Moments later the class was over and the students are having some time for themselves as Y/N was stretching, getting warmed up as the next class would be a training at Gym Gamma.

He saw that Denki and Mineta were talking about some news about team ups and what not as the H/C haired teen couldn't care less as he was walking outside the room. 

In the boys locker room, Y/N was finished changing with his costume as the other guys started to noticed it.

Denki: Woah! Looking sharp Y/N!

Sero: When did you get a costume change?

Tokoyami: Dark color suits you unlike last time.

Some of the guys praised Y/N as he thank them, releasing a small sigh as he was happy that he had gotten a small costume change as he looked at Denki for a bit.

Denki: Something wrong?

Y/N: Ah... n-nothing... (Now I can see what Jack and Senkai are talking about my costume...)

He let out a small chuckle as he started to head out of the locker room and towards Gym Gamma.

Ectoplasm: Now, let's work on improving you ultimate moves today, too! If you haven't completed the assignment to have at least two, work on that. If you already have two, then continue developing them. 

He said as Y/N walked on the top of the rocky field as he was thinking of combinations to use. He have too many Kamen Rider's special abilities at his disposal as of now. Once he reached the peak, he started to look at his arm.

Y/N: The message is still at temporary. Either that it may had affecting with Eri's quirk, or I'm still not ready to use it...

He said as he sighed and proceeded to use his quirk. He proceeded to use Ryuki's quirk, Dragon as fire breathing was the most prominent of it as a beeping sound was heard. Next, he proceeded to use Drive's quirk, Type:Speed as his agility was improved greatly. Finally, he finishes it off with Decade's Dimension, as he sends out some monsters that previous Kamen Rider's had faced.

Y/N: Good thing that they are just copies, if this were real ones I would flip.

He said as the monsters started to attack as Y/N gets started. Y/N throws out punch after punch as he used Ryuki's quirk, blowing flames at the enemies as he started to run in a circle, blowing flames as it grows bigger and bigger as a bright red whirlpool of flames appeared, burning the opponents as he stops.

Y/N: I guess that's two, but, I think I can do more...

He said as he was about to start over again, a voice started to pierce the air.

???: That was amazing! Sweating nitroglycerin out of your body and turning them into explosions makes a nice attack!

Bakugo: HAH?

???: Does secreting acid affects your body? Does it burn you?

Mina: Wha?

???: Maximizing electric voltage can cause your brain to fry, try starting small then work your way up!

Denki: I mean, that's nice and all. But, who are you?

The blond haired teen asked as Y/N started to look from where his classmates are and what he saw was rather... surprising.

A man with black hair that has apparently have some of hair standing up, and a pair of black eyes stared at Y/N's E/C ones as his clothes consists of a shirt under his brown coat, jeans, and a pair of rubber shoes.

Ectoplasm: Ah, sorry. I had forgotten that we will be having a new teacher today. Well, I guess here you are now. Can you introduce yourself.

He said as the man nodded, looking at the class 1-A as Y/N couldn't believed that this was happening.

"I'm Sento Kiryu, and I'm going to be your Physics teacher starting today!"
