For her faker form she will be in a constant state of being komi with big eyes even when serious she still has big eyes

In her second form she would still pretend to be komi but its fused with the creatures sadistic thoughts her eyes are constantly closed with a black sticky substance leaking out of her eyes as well as a grin with sharp teeth she cannot open her eyes but she can still see

Then her 3rd form comes in wich is wayyyy taller her face also is completely enveloped in the black fluid same for her hands wich became claws her eyes became big and bulgy and her mouth became a sharp toothy smile im this state she will hunt anything down and be mostly a brute but do be warned she is still very smart

This entity is an in universe yokai taking the form of komi and trying its best to replace her

She would never hurt tadano becouse of her pretending to be komi and also strangely having a crush on him

Her first victim is yamai and she will get a kind of comic story

Yamai gets invited to the school at midnight by what seems to be komi but so her perverted ass goes to the school and she looks around until komi appears but she had big eyes and no mouth yamai found this odd

She tried to talk to komi but komi approached her her eyes closed and a weird sticky substance and she began to sing

After that

She makes yamai hallucinate about the corpses of her friends and even komi herself

Later yamai goes to the kitchen and grabs a knife and a lighter and tries to kill this beast yamai loses but as a fail safe she puts the school on fire yamai almost dies and gets out of the school not knowing the entity is still alive
