Arumi Asahina

Sasshi's best friend and classmate, she is also 12 years old, having practically grown up together with him in the Abenobashi Shopping Arcade. A sensible and pragmatic girl who is a foil to Sasshi. Arumi's eccentric father and stubborn grandfather run a French restaurant in the Shopping Arcade known as the Grill Pelican. It appears, however, that the Asahina family will be closing up shop in the near future as part of redevelopment in the area and moving to Hokkaido, forcing Arumi to leave Sasshi behind. She expresses a strong distaste for every world that she and Sasshi visit.
