This is an interesting one. I can honestly say I'm past this phase, but here's "what was and when."
Rukia Kuchiki. As much as I think Bleach is repetitive and nothing but reiterations of deus ex machina, I had an enormous crush on Rukia. It was to the point where I would have dreams about her character. I even named a star after her. Yeah. That was when I first learned what anime is, my sophomore year of high school. (Bleach can be likened to a gateway anime.)
Hoshi no Kaabii. Yup.
