You are Takemichi's older sister, even though you are indifferent and cold, you still care about him

currently you are looking for Takemichi because he left the house and you are worried, when you find him you see him being beaten until he has bruises and a nosebleed because he is protecting Hina

"DON'T TOUCH MY YOUNGER BROTHER!!" you scream and hit him until he gets hurt and he runs away

"Ah- big sister" takemichi says
