I'm Gonna Be An Angel! (Japanese: 天使になるもんっ! Hepburn: Tenshi ni Narumon!) is an anime produced by Studio Pierrot. A manga was also released in Japan in 1999. The anime was licensed for release in the United States by Synch-Point, but its domestic distribution license has since expired. The American DVD release was never completed, due to poor marketing and distribution, and thus, poor sales. The manga has not been licensed for release in the United States.
I'm Gonna Be An Angel! is the story of Yuusuke Kamoshita who is living alone until he literally stumbles across a naked girl in a forest, a very energetic girl named Noelle. Noelle and her entire family proceed to move into Yuusuke's tiny home, replacing it with a huge plastic-looking castle, and disrupt his life. Shortly into the series, Yuusuke writes a note to his crush Natsumi Suzuhara apologizing for a few "incidents", in which he also exclaims that she is an angel to him. Noelle later finds the note and decides she wants to be Yuusuke's angel. Silky and her minions interfere as the series goes on.
