Arisa Ahokainen

Arisa is a half-Japanese transfer student hailing from Finland. The main reason she moved to Japan was because she loves its diverse culture and more specifically has a strong admiration for the Akihabara culture. She first encounters Tamotsu Denkigai when shopping for a specific figurine to which she also befriends him as an ally in both force and interest. She loves cosplaying and despite being a regular human being, she possesses unaturallly superhuman strength compared to that of Tamotsu and Matome Mayonaka, having studied in many different martial arts styles, and as well as the fact that she was temporarily trained by a Chinese martial arts master.
