Btw, for Matsuki and Oddball, what might be their personal items?
Hmm, I suppose the typical utility things: a change of clothes (a spandex-like exercise outfit) and personal grooming stuff (brushes, makeup, etc). For extra non-utility items, she would have a necklace with an intricate twisted metal design, and a personal music player loaded up with the equivalent of modern J-pop.
