Tsundere and Vanilla, always a lovely combination to see.
Still...Yeah, I suppose expecting her to bring him to an arcade for the match would make sense, but well, it's Hentai, so there had to be an easy way to transition, eh?
Great ending though. Heh, so his single minded determination and stubbornness won her over, eh? That's nice. Also, she let some of that dere slip, but alas, he didn't catch it and she went back to her tsun attitude. But hey, that's what makes a tsundere so adorable.
