Kotarou Higuchi, a classical Ordinary Grade School Student suffering from Parental Abandonment, suddenly finds himself glomped by his new Verbal Tic -afflicted DitzyGenki Girl neighbor, a girl named Misha. She assures him that she is an angel in training and she is on Earth to take care of him. She then proceeds to demonstrate it enrolling in his same school (although since she is seemingly older and assigned to the High School section, she still escapes to the elementary wing to watch over Kotarou), following and glomping him at the minor chance and often without excuse, for amusement of Kotarou's best friend Takashi Ayanokouji (aka Ten-chan). This is to the great annoyance of Koboshi Uematsu, a girl who has a crush on Kotarou, who immediately sees Misha as a rival.Complications (and hilarity) ensues when, after Kotarou discovers that Misha is really an angel, a demon apprentice named Shia arrives in town. But, while Misha is just inefficient as an angel, Shia is absolutely awfulas a demon, since she is anemic, sweet, considerate, and a perfect House Wife. Then, when Misha and Shia move in together, even with both girls being aware of each other identity and alignment, it doesn't take long to predict that things are not going to end well.This series is incredibly sweet and light-hearted, even with the dark past of almost all the cast. The original manga of this series was drawn by Koge-Donbo, the mangaka who designed Di Gi Charat, so expect the same kind of Moe Moe character design.This series provides examples of:
The Ace: Ten-chan. He consistently has the highest marks in class, is good at sports, and a lot of girls have crushes on him due to his good looks, not to mention his energetic and friendly personality. However, he reveals that he actually works very hard to achieve such high marks.
This troper found the manga's ending to be meaningful and empowering. Kotarou is separated from Misha, but does so on his own terms and finally gains the strength to start living his own life. He doesn't get the girl but he becomes a better person than he was at the start of the series, and that's better.
But Now I Must Go: More like But Now You Must Go, when in the manga Kotarou asks Misha to use her magic to take away his ability to see the supernatural, meaning they won't be able to see each other anymore.
Fate Worse than Death: Failure to pass the angel or demon exams will result in Misha or Shia to be deleted from existence and all memories of them expunged.
First Girl Wins: Manga-only, subverted; Kotaru knew Koboshi first, but Misha is introduced to the readers first.
The Glomp: Misha is very quick to do it to Kotarou. Heck, the title is a contraction of Pittari Tenshi, or Clinging Angel!
Half-Human Hybrid: Kotaroh and the first Shino are half-demon. Kotarou and Shino are descended from the first Shino and as such are about one-eighth demon.
Good Colors, Evil Colors: Misha (angel apprentice) wears a black dress and (demon apprentice) Shia's devilish outfit is mosty white, but when we see (full angel) Sasha's impolute white dress a possible explanation is both Heaven and Hell dress their younger members with the colors of the "Other Side".
Likes Older Women: Ten-chan and his infatuation with Shia, who may or may not be Really 700 Years Old, but is significantly older than him in any case. Even not counting that, Ten-chan is STILL a 12 year old boy who ends up seriously perusing a relationship with a girl who physically appears to be 19.
Living with the Villain: Deliciously lampshaded and subverted, since Misha and Shia don't see each other as enemies, even if as a race, they must... but again, both are the most ineffective members of their respective groups, so...
Missing Episode: A side story where Kotarou has a crush on a girl in his study class. The only indication that this side story exists is that it was mentioned by Koge-Donbo in the Writer's Talk afterword of the Pita-Ten Official Fan Book Vol. 3.
