A minor Original character by Rakurakutei Ramen. Aiina is an American friend of Elza Straherz with Blonde Hair and Green Eyes.
In the 4koma, she only appeared for a brief visiting arc, but sometimes ships gifts and letters throughout the series. Some sort of standing rivalry existed between her and Mifilinah Jegell, but the two put their issues aside in the quest to get Elza to have proper sex with Mifi.
In Ghostrick Live, she plays a more central role.
