I'm Gonna Be An Angel

The Thing at the End of the Tunnel (1x10)

:

Natsumi has a fight with Kai. Yuusuke and Noelle go to a festival and Noelle receives a little creature called Bunbun ("Boonboon"), who supposedly will turn into a angel with 7 color wings if it's taken care of properly. Yuusuke has a bad feeling about the little guy though since it refuses to let Noelle sleep in Yuusuke's room and she even left for school without him the next morning. When it goes cray and eats all the food at the table when Noelle runs off to get some napkins, Yuusuke is convinces Bunbun is bas news, but Noelle refuses to believe him. When Yuusuke yells at her to get rid of it, Noelle seems like she's about to say "I hate you!" but instead says "I still love you!" so Miruru pops out, disappointed that her plan to break up Yuusuke and Noelle didn't work. Bunbun then goes berserk and drills holes into the walls of the house, making the whole thing look like Swiss cheese. Bunbun goes after Noelle and Yuusuke saves her. Lucca then fixes the old Bunbun into a proper, non-evil, creature and Noelle celebrates.
