Ayato is a narcissistic prankster who has an obsession of being the best due to his upbringing by his mother. Known as the troublemaker of the household, Ayato is an attention seeker and loves mischief. He looks down on others and loves to bully and tease people, bragging about himself and sometimes commanding everyone to call him "Ayato-sama". He refers to himself most of the time as “Ore-sama” (Yours Truly in the English Dub) and refers to Yui as "Chichinashi" 「チチナシ」
