Arina is a young girl with short, straight dirty blonde hair and olive-green eyes, and she wears circular glasses. Arina is usually seen with her school uniform.
Arina seems to quite a mature child but also similar to Kurumi. She looks up to Haruhiko and the others since Kurumi said that they were really dependable.
Kurumi asked Team E for help since Arina's cat, Rudolph had gone missing. They accepted and started looking for in a cat-mansion, where they managed to find it after solving the problems with the mansion and a Phantom. Arina became very happy when they managed to find Rudolph and therefore offered to help Team E to clean the mansion.
Kurumi and Arina are very close friends. Arina came to Kurumi when she needed help, suggesting a good bond between the two.
