In a far eastern land, there was a generally quiet shrine in the mountains. Hakurei Shrine's shrine maiden, Reimu Hakurei, didn't have much to do. Reimu: *Sigh* Wonder if there's any work (something amusing) around. And so, because of her careless words, a large amount of ghosts and such suddenly came barging into the shrine. You reap what you sow. Reimu: Ueeh, what the heck is this?! Reimu quickly got down to business, and began evil spirit extermination. --- Reimu: Hm... at this rate, the shrine will be ruined again. Looks like there's no other choice. I'll find the cause and crush it from there! Somehow, (I'm not making fun of the shrine maiden's "somehow" method) Reimu felt that the lake in the mountains behind the shrine was suspicious, and so she promptly headed towards the mountains. Reimu: This place is definitely suspicious. There are an amazing number of evil spirits. Reimu: I'm getting excited, I'll finally get to do some work (evil spirit extermination) again!! --Meanwhile. Marisa: Hmm... what's this magic power? The possessor of a large capacity of fierce magic power, Marisa Kirisame, was suddenly tempted by a vast magical force. Marisa, intent on making this power hers, headed towards the source. Marisa: Lovely. Where'd all this insane heap of magic power come from? Marisa headed towards the lake without Reimu knowing. Well, that's what she had intended... And so, the two went to the lake for separate reasons... hmmm.

She's an ordinary girl, even though she's a magician. Her personality is somewhat self-confident, but she has enough power to support her confidence too.

She's very intelligent, and is looking for power, but is still a child. What she does in her daily life is unknown.

She looks even younger than Reimu, but their ages are very close.

I think they both are a bit off from average...
