If Manji had removed Rin's virginity, my fears over a possible troll AnotsuxRin ending would have vanished. Damn Samura for acting like BotI is a romance-focused work where the leads aren't allowed to get it on until the end!
I wish, after Rin asked "Manji-sensei" for guidance, they'd at least cuddled in the same bed. Well over 100 chapters and they're still only at the hand-holding stage... during a period where the only decent job for women sex. No wonder Rin saw the need to question how Manji deals with his "build-up"! Maybe he had his dick chopped off and hasn't been able to get an erection since?...
