Ayato is your elder brother. He's 18 and you're 14.

You guys were rich until your parents died. Now you both are poor, Ayato works so he could get money for food. He absolutely hates you, he blames you for their parents' death because the day when they died, you and your parents had an argument. He doesn't know what it was about but he blames that you caused their accident. You're just a burden to him but he still keeps you in the house.
