Maedomari (前泊) is an acquaintance of Shunsuke Otosaka. He along with Medoki are responsible for erasing the existence of Shunsuke from Yū Otosaka and Ayumi Otosaka's memories.


Maedomari has blueish black hair and light blue eyes. He dons a gentle face. He wears a light blue vest over a white short sleeved shirt with a light-dark blue tie. He wears grayish-blue pants with dark grey shoes.


He is able to pinpoint and erase memories from someone but has to touch them in order to do so. The process takes a long time as noted by Shunsuke.
