This Hinamatsuri story summary begins with a strange event that changes Nitta’s life forever. One quiet night, a metal capsule suddenly falls from the sky and hits him on the head. When he opens it, Nitta discovers a young girl named Hina inside.

She looks calm and expressionless, yet it quickly becomes clear that she has extraordinary supernatural powers. From the moment she appears, Nitta’s peaceful routine is turned upside down.

At first, Nitta wants nothing to do with her. However, he soon realizes that he cannot simply abandon Hina. If she does not use her powers regularly, she becomes unstable and may release destructive energy. This danger forces Nitta to take responsibility for her, even though he never asked for such a burden.

Hina’s abilities can be useful for certain yakuza missions, and Nitta eventually understands that her presence can make his work easier. Still, there is a constant risk. If Hina becomes angry or confused, she can accidentally cause serious damage. Because of this, Nitta tries to teach her how to behave, how to interact with others, and how to live a normal life.

Their daily life becomes a mix of comedy, chaos, and unexpected moments of warmth. Hina struggles with simple tasks, while Nitta struggles to keep his world from collapsing. Despite the challenges, they slowly form an unusual bond that neither of them expected.

In the end, this Hinamatsuri story summary shows how their relationship develops into something meaningful. Their strange journey is only the beginning, and many unpredictable adventures still await them.
