You Got Your Wish, Senpai! / 'Sup, Senpai?!.
Senpai buys an erotic vampire manga which Nagatoro steals. Reading it Nagatoro realises the story is actually interesting, but does point out the cowardly human protagonist clearly resembles Senpai. Nagatoro jumps on Senpai pretending to vampirise him, only to be repelled by the garlic from his lunch and accidentally grabs his crotch, embarrassing them both, though she takes the opportunity to tease him for becoming aroused. The next day Nagatoro proposes a game of accurately poking where each other’s nipples are under their clothing, with the prize of a ticket to force the loser to do any one thing without refusing. Senpai agrees, hoping he can force her to stop teasing him...
