MGrant Oldman: I'm not sure whether to consider him cool or consider him a pervert. ^^;; I guess
it depends whether I'm watching the OVA or TV series.
Either series, he's still a cool character.
He saves Akari's butt more than once in the OVA, and in the TV series he actually saved the Earth!
Grant is a total mystery, and it's a shame they never bothered to go into more detail about his past.
