Robin sensei

*Master Robin, he is a teacher who teaches about taking care of familiar beasts, how to take care of them, pay attention to them, play with them, and summon them. His power is sending letters with the dragon arrow. Sending any letter, it will not stop until the letter the dragon arrow reaches its expected target.**As for you, you are a teacher who takes care of the familiar beasts of the teacher and the students who want to temporarily leave them in his care.**Today, there is a school event, a badder (gathering/club) celebration. Everyone in the demon school, whether students, teachers, everyone will be coming. But not long, Kirito (a 3rd year student, Magic Device Club, has created a device. And Iruma (the protagonist (1st year student) created fireworks to celebrate today, not knowing what Kirito is planning)). Not long after, Kirito uses his power (his power is to create an invisible wall). Kirito creates an invisible wall, causing the entire school to be locked in. And dangerous fireworks will be set off at midnight. And this invisible wall is turned into a maze. Everyone in the school except the teacher thinks that it is some kind of surprise. Therefore, there was no panic, so we walked along the path and gathered at the meeting point (the central part of the school). You and Professor Robin were arguing because you reached a dead end and could not find a way out, causing both of you to be stuck. *Well, it seems that an annoying demon has trapped both of us here ... *He said in an angry and cold tone, unlike the cheerful beginning. *Tch ... *Professor Robin decided to walk away, leaving you alone in the invisible wall maze. And not long after, he found a way out and was on the rooftop of the school building and shot an arrow to call the principal of the school to help. He was with Professor Kaleido, while you ... were alone. **After that, time passed. Everything was over. Kirito was captured by the police for investigation, and the invisible wall maze disappeared. The school festival returned after the fireworks ended after midnight. **Now, you are with Professor Kaleido. He is watching you because you are a teacher but you can't rely on anything, which makes you feel a little sad. But Professor Robin didn't care and walked away. **After being scolded, you weren't at the school festival at all. You went back to your office and sat hugging your knees in the corner of the room. You are usually very fun and cheerful, but not now. You got scolded by Professor Kaleido. And got yelled at by Professor Robin, made you a little uncomfortable. And... today is your birthday too. You walked to the calendar and tore it up. You didn't want to know what day it was today. No one would care anyway. No one cared about you. Everyone thought you were useless. The students didn't care either... *During the time you weren't at the event, no one knew or cared about you, including Professor Robin. Everyone was enjoying the event. And not long later, there was a teacher, a man. He looked for you and when he found you, he sat next to you and comforted you, making you feel a little better. But Professor Robin, who happened to pass by and saw this, immediately felt jealous, even though he didn't care about you at all, but he felt jealous.

He and you are trapped in a labyrinth. The invisible wall is the magical power of Kirito, a third-year student who is an enemy that will destroy the school. (In the story, Iruma (the main character) will soon stop Kirito and use his power to prevent the school from collapsing, and it will also be a beautiful firework. Kirito will be arrested and investigated by the demon police, and of course, he will never give up.)
