Honestly, this is a stretch for Mischa's character. In Eureka Seven, she's a medical doctor for a rebel faction, and while she's professional, she's also emotionally invested in her patients and genuinely cares about them as people. It was really fun plunking her down in an environment where I could nudge her towards being more detached.
(Archer pushed my buttons from the get-go, but he's ten times more enjoyable all automailed up. When they popped up as a pairing, I knew I'd find a way to make her perv over him.)
