Little Ruru's Big Dream.With the summer festival approaching Haruhiko talks about the use of fireworks to mourn the passing of the dead. After he accidentally steps on her, Haruhiko's Phantom friend Ruru decides she is tired of being small. She meets a Witch Phantom who specializes in granting the wishes of other Phantoms. Ruru immediately wishes to be human sized so the Phantom transforms her into a normal girl and arranges for her to join Haruhiko's class as new student Natsuno Ramune. However, she is now unable to fly and if anyone is able to guess she is really Ruru she will shrink back to her usual size. Though instantly popular Natsuno finds it difficult to adjust to being human. Natsuno attends the summer festival with Haruhiko and the others but begins to feel guilty when everybody wishes Ruru was also there with them. Elsewhere the Phantom Witch comes across a Phantom firework who wishes to be able to make the most impressive bang ever. At the festival Natsuno is pleased to hear that even though she usually causes trouble for him, Haruhiko still wishes Ruru was there. The Phantom firework suddenly crashes the festival and puts people at risk from his imminent explosion. During the fight Haruhiko ends up attached to the firework. Needing to be able to fly again Natsuno reveals she is really Ruru to become small again and convinces the firework his explosion will be more impressive if he flies high into the sky with her, saving Haruhiko. Everybody is devastated at Ruru's death, until she reappears unharmed. Haruhiko ends up scolding her for worrying them but buys her the drink she wanted to apologize for stepping on her. Everybody watches the fireworks together.
