Summary
Genya inhales sharply, refocusing on Ume’s nails. “We’re not jumping Kanao.”
Ume scoffs. “Pussy.”
“No,” Genya growls. “Survivor. You think her sisters wouldn’t see through that immediately? Kanae and Shinobu would destroy us. Like—obliterate, disintegrate, wipe-us-from-history destroy us.”
Ume pauses, considering it. “Yeah… Shinobu scares me.”
“Good,” Genya mutters. “Because I’m terrified.”
Ume places her foot against Genya’s thigh to keep her steady while she starts applying another coat of purple polish to Genya’s own nails. “Well, then what can you do? You don’t have any money, and Christmas is in two weeks.”
Genya groans, leaning back until her head bumps against Ume’s dresser. Her life feels like a long, irritating prank the universe is playing on her personally.
(Or: After losing all her money in a bet, Genya is left to figure out what to give her older sister for christmas now that she’s a pathetic broke mess.)
