I thought it was creepy eldritch horror girl with normal girl who can see she's a horrible monster yuri and was proovoved I DONT KNOW because I didn't read anything else but the chapters Michiru was in at the time

her freakish nature captivates me

I like how she sits down across from Miko and then gets up and sits next to her and also how on a multiple choice test she got a zero and said "I tried my best :D" Or when she memorized a cars license plate after it almost ran over Miko to I only presume to go kill them
