Krotoslol said: That's why I don't buy into Rinnosuke/Marisa stories. It's difficult to be attracted to a girl that you've seen grow up from a child.
Well, unless Morichika met Marisa at a very early age, attraction between them is not out of the question as they would be clear of the Westermarck effect (suggested to apply only from birth to age six).
It is very likely that any romantic attraction would be one-sided from Kirisame's part but who knows with Morichika's nature as a half-breed?
Looking back, Rinnosuke would probably wonder why the sweet adorable chibi who clung to him when he was still at the Kirisames turned out into the girl he sees right now...
