Marisa is an outgoing and informal person. Hieda no Akyuu states that her personality is condescending, but she has a sophisticated side to her that tends to be interesting.[2] She socializes with many inhabitants of Gensokyo and is friendly to both human and non-humans individuals. She's quick to act if she hears or sees anything interesting,[3] sometimes doing dangerous things to satiate her interest at the time like when she follows an eagle on a whim in the middle of a blizzard.[4] She speaks in an informal manner and typically uses the sentence ending particle ze (ぜ). "Ze" used at the end of verb stems delivers a "boyish" and "impolite" sound to the listener/reader. Ze is mostly used in a context to express one's will to act (similar to "let's" in English), and using it in other cases sounds somewhat unnatural, perhaps "phony" or "showy".
Speaks in measured phrases, ends calmly, rarely wastes words; slight shrine-formality.
