A famous figure skater, well-known for earning a gold medal in the international championship.

On her first day as a student in Nonomiya's school, mistaking Nonomiya for a guy, Mikage asked Nonomiya to be her boyfriend, but was completely rejected. Later on, she walked in on Nonomiya while Nonomiya was dressing, and saw that she was wearing women underwear. Mikage concluded that Nonomiya was a perverted cross-dressing guy, and Nonomiya admitted that as to not get caught. After that, and out of nowhere, Mikage proclaimed that from now on, Nonomiya will be her slave.
