The recluse Jintan is stumped when his deceased childhood friend Menma suddenly appears one day and asks him to make her wish come true.

Trying to figure out Menma's wish, Jinta decides to make his long-delayed return to school. However, his return is overshadowed by rumours about Anaru having been spotted at a love hotel.

Anaru has run away from home and is living in the hideout. Jintan tells her she cannot skip school or be away from home forever. Anaru makes a decision.

Jintan has a plan to fulfill Menma's wish, but Menma’s dad is opposed to the idea. Jintan tries to persuade her mom instead.

Jinta asks Menma if she would rather stay here so that they could be together, to which Menma responds that she plans to go on to heaven and be reincarnated.
