One of ArS's members. A gloomy glass artist, Akio is skilled with small works of art like making glass beads. Because he adores things that sparkle and shine like glass handcrafts, he is drawn to Hikaru Orihara's ice sculptures. Akio feels depressed and negative often, but because Shiki Amabe looks after him during times like that, they frequently work together.

Due to growing up surrounded by his brutal sisters, he developed gynophobia, causing him to take cover and hide at lives and events.
