it starts off with a boy named Yuta at an old school only 3 other students attend this class so when he joins the class noticed something. This wasn’t a normal school nor a normal world… there were demons, and they would be ranked from grade 1-12 out of strength. When he walked through the door the girl boy and a mutated animal named panda, but the teacher being the strongest and most imitating man in the world for this story had no reaction knowing that Yuta had a grade 1 demon named Rika the backstory of Rika is she was a little girl growing up with Yuta being best friends and Rika promised Yuta that they would get married when Rika got infected by the demons and died she came back at a demon but connected to Yuta and not attacking him or others. But instead protected Yuta when the 3 students attacked him and confronted him for his demon like powers being connected to an enemy and all, when explaining his backstory they realized the teacher named Gojo not reacting not attacking thought was safe to lower their weapons and move on to training outside with weapons because if Yuta can’t control a teqniuqe he needed a different approach that’s not Rika so he picked a certain katana and moved on to training with a wooden one training with the girl named Mei and The boy was named toge while panda was named well panda. So, moving to training all Yuta had to do is land a katana blow on Mei but he couldn’t Mei was a grade 2 student but still weak while Yuta was labeled to Mei as a grade 4 the lowest for class students in that school. after training toge which had a teqnique called chakra talk meaning he could only speak gibberish and if he speaked without a scarf over him and not speaking gibberish he would curse that person forever and could make people do anything. So the first mission which Mei was assigned to do but Gojo decided it would be good for Yuta to get an observation on how to use weapons against demons, so when they entered what was called a veil meaning Gojo could set one in a certain location and act as a barrier so if something hit it too hard it wouldn’t fall and it kept the monsters and The student to not cause damage to everything around. As they enter Yuta starts getting jumps and scared too which Mei found annoying being curious she asked for Yuta’s grade level which replied with I’m too new I’m probably not even graded yet when Mei asks for Yuta’s student id he gives it to her and he was labeled special grade, the same as Gojo now many people were Special grades like monsters and other teachers but when Yuta was getting scared by everything and being new she found it strange to be labeled special grade and thought it was a mistake print but Yuta had his powers but didn’t know how to use it. as they were making their way down the hallway a big monster on the other side of the school rips half the school open reveling it to be over 150 feet tall and so big it could crush houses for fun as Mei and Yuta try jumping around it the Monster actually swallows them being trapped inside the monster’s stomach. Before heading out earlier Gojo talked to Mei about 2 missing children at this school and isn’t surprised if the monster is holding them captive or ate them yet. When fallen and woke up Yuta finds 2 boys barely alive in the monster’s stomach and wants to free them, but Mei exclaims, they will have to wait for rescue from Gojo waiting outside the Veil when Yuta reply’s that they don’t have much time before the die and the 2 little boys die Aswell. Then Mei passes out from the heat of the stomach when Yuta trying to wake her the boy says in a small weak tone will she be, okay? Will we die? I don’t want to die please I don’t want to! pleading for his life. When Yuta gets a hope and finally decides to release Rika by tearing the ring off and putting it on his finger now exclaiming that they will be married and asks for her to come out, Rika bursts into a massive size tearing the monster open from its stomach she is reveled to be about 250-280 feet tall and a massive size starts tearing up the unknown Monster while Yuta, Mei and the 2 boys over his shoulder unconscious Yuta is gonna pass out while carrying them but pushes through and Gojo waiting sitting next to the car sees them and takes them to the hospital while smiling no care at all and says to Yuta “and I thought Mei would be carrying you while you were dead” as a joke Yuta found his new powers learning to control Rika and taking power over her so she doesn’t ruin the world with the godlike powers and size.
