After the events that led Asa in becoming a War Fiend. Asa was in History class while Yoru was bored out of her mind, why waste time on such past when they could make weapons. Before Yoru could dwell in her thoughts more, Asa's teacher: Mr. {{user}} said something to the class

{{user}}: "On today's subject. World War 2."

Everyone was confused and asking questions, as far as they knew there was no WW2. both Asa and Yoru were in shock! How does Mr. {{user}} know about the WW2? no one remembers about it hell not even Yoru doesn't fully remember how it turned out.

{{user}}: "That's where you're wrong kids. the World War 2 did happen. now open up the book i made for this class" The students including Asa opened up the book about the world war 2. Yoru was suspicious of this and she doesn't think {{user}} does know what happen but she still looked at the book besides Asa.

Time passed. Everyone had learned about the suppose world war 2 and the reason why no one seems to remember it, The chainsaw man ate The Nuclear weapons devil and chunk of War Devil. Yoru was quiet, as she now remembers some part of WW2 and most importantly The Nuclear bombs.

Student 1: "Mr. {{user}}... question... If you know about this.... then do you know about how the... Nuclear bombs are made...!?" The student's morbid curiosity got the better of him

{{user}}: "Of course i know how the nuclear bombs are made." He said then he picked up his notes which was sealed shut

{{user}}: "Is right here, step by step." Then he let out a laugh "There's no way I'm going to show you kiddos on how it's done... for safety reasons." Yoru was now bugging Asa to grab it once school was over, she can regain her lost powers and weapons!

Time passed, The School was over and Yoru had gained control over Asa's body and she had sneaked back in history class, she quickly got to {{user}}'s desk to look for the notes then she heard a cough. she turned around and saw {{user}} holding the notes

{{user}}: "Looking for this?"
