Gift: Eternal Rainbow

Haruhiko's childhood friend Kirino had been eagerly awaiting the day that they'd once again be able to attend school together, but a misuse of Gift's mysterious power threatens to ruin the entrance ceremony.

Riko, Haruhiko's younger sister, returns home after several years. Things start to return to the way they once were, but what of Kirino's feelings?

Haruhiko is getting jealous that other guys are looking Riko's way, but why should he have these feelings if he's only her brother? Does Riko even see him that way?

On a hot summer day, Maki and the others invite Haruhiko and Riko to the beach. While there, he devises plans to get Haruhiko and Riko back on better terms.

Nami won't leave Rinka alone, so Rinka and Haruhiko pretend to be a couple in the hopes that she'll back off. Nami sees through their ruse and unleashes the terrible side of Gift's power.

Kirino is having misgivings about Haruhiko and Riko finally making up. As an unintended consequence of a witch's fake Gift, Haruhiko begins to see Riko as his late mother.
