Two sisters in their twenties and teens, Akira and Nozomi, are struggling to make ends meet after their father left them buried in debt. Akira, the older sister, is capable but often sabotages herself, while Nozomi, the younger, wants to help her sibling get ahead. On full moon nights, Nozomi can inexplicably think of numbers that have a high chance of hitting – lottery numbers, winning bets, or other lucky draws. Once a month, the sisters treat this ability as a treasure hunt, using Nozomi’s sketchbook notes to try to claw their way out of poverty. Their days are a mix of dead-end part-time jobs, near‑misses with fortune, and the warm, sometimes exasperating bond between a smart‑but‑unlucky older sister and a gifted‑but‑younger sister who just wants to see her smile. The story follows their daily life and monthly gambles, blending slice‑of‑life humour with the small, hopeful moments that come from chasing a lucky break.
