16‑year‑old Itiko Sakura has everything – health, beauty, wealth, and decent brains beneath the shell of an ash‑blonde. The reason is clear: Sakura can attract "energy of happiness," adding to her already substantial stock from birth an extra share of someone else"s fortune. This vampirism brings misfortune to those around her – in the end, the girl is lonely, lives only with an old butler, has no friends, and regards others as second‑class beings. The goddess of misfortune Momiji arrives to correct the imbalance – and immediately suffers a terrible fiasco! Itiko is not so simple – it seems that the blood of luck gods flows in her veins, allowing her to fight on equal footing with the celestial guest and even call her a flat‑bodied from the heart! Well, the goddess has nowhere to rush, and she moves from a storming assault to a systematic siege, trying to study her enemy, his strengths and weaknesses. Constant skirmishes benefit both heroines: one gains willpower and motivation, while the other starts to think and work on herself. Momiji realizes that instead of a harsh depletion she should help her new acquaintance, and perhaps even a distant relative, gradually become simpler and better. Itiko also comes to understand that life is happier if one spends the blessing of fate not only on oneself. After all, what is this energy of happiness if you can"t even share a festive cake with anyone?!
