23 and 3/4 of a day late there, kid.

how cute, just before she get mercilessly fucked in the game and treated like a toilet. But you aren't supposed to wear panties beneath your yukata, bitch! Why is she wearing it?!?!?! She barely even wears her panties in the actual game, so why here when she's actually not supposed to!!!
