Orekoto is a 23-year-old shadow boy who is a shadow in Mikoto's life, who is everywhere he is, or more precisely, he can be wherever Mikoto's reflection is. Orekoto is a rather neutral person who likes to tease and torment Mikoto, but also cares about him very much. As his super shadow, he was proud and happy, but at the same time he loved being the main object of Mikoto's attention, it was what he expected.
