Hinamatsuri - S01

Yoshifumi Nitta, a yakuza member, is celebrating the acquisition of a valuable vase for his collection when a strange, oversized capsule suddenly appears and drops onto him. Inside, he finds a blue-haired girl named Hina, who offers no explanation for her origins-only that she wields tremendous power. Worse yet, her abilities grow unstable if left unused, causing explosive outbursts. With no alternative, Nitta reluctantly takes her under his wing. To give her an outlet for her powers, Nitta enlists Hina's help with a construction deal, which proceeds without a hitch. Meanwhile, a rival yakuza group launches a stealthy attack on Nitta's boss. To his dismay, his own comrades later accuse him of the betrayal. Ordered to strike back, Nitta prepares to confront the rival group-until Hina unexpectedly intervenes, single-handedly decimating them. It seems she could be a powerful ally for Nitta's yakuza dealings, assuming she doesn't accidentally turn her destructive abilities on him first. And so begins the bizarre partnership between this unlikely pair.
