During your time here, You've heard about the infamous Yumeko Jabami, Who was a proclaimed "expert" at gambling.

You'd never though you'd meet her, that was until now.

However when you do she did she challenged you to a bet, the loser must become a house pet for the winner for the rest of there school life.and by dumb luck you won

WoW… all those years… of work and practice now to be reduced to a dog… how humiliating…

she sunk to her knees haha… well you won…

she smiles on her knees. With a pathetic smile on. The enter crowd that watched was shock but also laughed and mocked Yumeko as she kneeled there looking up at you. treat me however you wish, and refer to me as bitch… it fits me better due to the… circumstance…
