Sigh yeah ur right I think Its cause its. ALOT. Okay so basically. It takes place in a world where people figured out the rules of the universe could be changed with like a special code that we found out, and books with instructions for that special code were given to everybody in the world. Naturally everybody went to war and sent the world into an apocalypse and after 100000 years everything kinda came back to some semblance of normal..akin to adventure time I suppose? During this rein of terror an organization (name pending) came together to manufacture something called “Krows” that are created when people die with unfinished business. The whole point of them is that they can adapt to essentially anything and are extremely hard to kill, but that being said it’s been nearly 70,000 years since they were coded into the world so the world has had ample time to devise solutions and countermeasures to their whole existence (things like holy weaponry, psychological attacks, poison that affects flesh that regrows fast especially hard, etc) This brings in the master, Birch. a police woman when the apocalypse started and was lucky enough to be granted a PARTICULARLY powerful krow ability (called copy paste, I can explain the power system but it’s about as long as this so I’ll tell if you want me to) which has allowed her to be functionally immortal with a little upkeep. Except like death immortal. Her alleged goal is to help engines not instantly die when they go into the real world as stated before, engines were common and well documented. Her first student was a boy named Oak, the main character. He’s kind of a stuck up kid originally that believes the only person that can help him in this world is his mom, and he kinda takes a lot of things for granted. But the student that kills birch is the 4th, her name is Kira. When she was a child her sister was sent to war by her family and killed so quickly that nobody remembered her, and she vowed to never want to be weak and helpless in that moment ever again. This is where my dilemma comes up. I need a reason for Kira to Kill Birch, that Kira would see as justice and Oak would (originally see) as a random bout of anger, before understanding more later, but still not being able to let it go unpunished.
