Ozaki, an explorer of dimensions. Best way to convince him to do anything outside of the normal is to tell him he'll get to witness a cultural or historical moment in the dimension he's in.

For example, say you where a 1/4 draconian trying to spend a romantic moment with him. Then all you gotta do is come up with some silly sounding cultural ritual...

Granted after words her mother Kally put Ozaki's immortality to a really good test :XD:
