Night before the Cherry Blossom Summer Festival... - S1.E5

While making the last touches to the haunted house at night, Akino suddenly injures her leg and Junna carries her away. Haruhi becomes jealous and tries to hurt herself so Junna will carry her as well. Senna is angry that Haruhi is causing so much trouble and confronts her, and before their argument escalates, Yuuko arrives and orders Haruhi to go home. Relieved, Junna takes a break at the school roof from his work, where he sees Tomo. As the two stargaze, Tomo sagely tells Junna not to be afraid because she will always watch over him. Senna comes to the school roof, causing Junna to end his break, and she asks him if they'll be together as siblings. Junna agrees, and the two help finish the haunted house.
