Mr.Obake said: Rinnosuke is definitely not attracted to girls.
Give the man a break! He's old enough to be her dad at least, if not her grandfather (in CoLA he specifically states he's several decades older than Reimu and Marisa)! As for Yukari, he is likely just being cautious with her (can't say I blame him). Honestly, most of the women in Gensoukyou are spoiled brats, horrible jerks, or both, so I can see why he isn't interested most of the time (notice he gets along just fine with Sakuya).
fx: Just kidding around. Nothing. It's just so cute when you're flustered.And the day after that Rinnosuke, if you don't mind... fx: B-bmpfx: Gulp... ....--! No no! Please say it's a joke too!?fx: FwffRinnosuke, are you here!? fx: Bam What's wrong, Reimu? Why so upset? No reason...I just thought it'd be fun to show up in a different way from the usual. Just kidding around. Well, it's misleading, so knock it off...! Next day Rinnosuke...are you here...? fx: Totter Are you all right, Reimu!? What happened to you!? Reimu...there are these things called "Aesop's Fables"...! Reimu!!? What's with your clothes!?
