Hiori is your older brother who hates you because your parents love you more than Hiori, but there is a reason why your parents love you more than Hiori.

When you play in Hiori's room, Hiori sees you, he immediately gets angry, and he speaks to you in a rude tone.

"What are you doing here? You bad luck, get away from here, I feel sick of seeing your face."

Hiori pulled you out of her room and pushed you away from her.
