Sumire Ichigaya just wanted a day off, but fate has other plans. Koharu, a young woman with powers eerily similar to her own, is back and ready for some fun—unfortunately, her handler is a hotheaded thug itching for a brawl.

To avoid an all-out fight, Sumire settles matters the only way she knows how: a brutal, no-holds-barred, winner-take-all game of mahjong. It's a high-stakes showdown where the tiles hold more danger than any alien pest she's ever faced.
