The title of the manga sums up the story, chu is the onomatopeic sound for a kiss. "Shite" being translated to roughly "to do" action wise and Bomb being the noise which resulted from a kiss. If that explanation only help to confuse you, just read on. The plot revolves around a 15 year old boy named Oozora Haruhiko, who was living alone in an old house while his parents work oversea. While moving in, he discovered a secret passage which leads to an underground laboratory. Inside the lab, he found a naked little girl sleeping in an egg shaped capsule. Oozora awoke the girl when he opened it, and decided to ring the police, giving the girl hot cocoa while she waited. When his back was turned the girl (Daisy) become a very lovely, built 15 year old. It turned out that hot food makes her older while cold food makes her younger. There is also the fact that if she kisses anyone she took on their form, so when Daisy kissed Oozora, he fainted dead away.

It became clear that Daisy was not just an ordinary girl, nor is she an ordinary android either. Though she may posses the super natural powers she is also endearingly human in a part girl part child way. Haruhiko decides to keep Daisy's existence a secret by keeping her home as much as possible, but things change when Daisy starts following him to school. As a result, Haruhiko passed Daisy as his half sister. Daisy's unusual nature is rather hard to keep as a secret and pretty soon some shady characters appears to whisk Daisy away for some sinister motive.

Kurita sensei manages to inject her own brand of humour into what would have been a rather predictable tale. Plus her characters are always so cute, particularly Andrew in this case :).

Ooozora Haruhiko
15 year old high school student, currently living alone since his parents are working over sea. A bit of a nerd, becomes a member of the Robotic club. He gets very embarassed everytime Daisy transforms into her older self, and often faints dead away. He is more comfortable with Daisy's younger transformation, where he acts as a sort of bossy older brother.

Daisy
This picture is Daisy's form as a little girl, her teenage form looks more like the cover above. Since Haruhiko always leaves her at home with the TV, that's where she learns about the world. It's from TV soaps that she keeps on calling Haruhiko "darling". It's also from this media that she becomes so enomoured of Usagi seishi (a send up on Sailor Moon and varioous other shows?). She loves all sweet things, because that's where she gets her energy from.

Andrew
American child genius with an IQ of 340, who graduated from Harvard specialising in robotic engineering. He suddenly appeared at Haruhiko's school, shortly after Daisy was discovereed, and he seemed to take an avid interest in everything she does. He sometimes mispronounced a few words, which leads to some embarasment for him, and you'll see him flicking through a dictionary a few times.

Shikishima Uran
The number one popular girl, before Daisy comes into the picture. Uran and Haruhiko used to go to the same high school, one reason why Haruhiko knows her. Uran is a terrible cook and she is always looking for some poor idiot to test her creation for her.

Robotic Club Leader
I include him just for fun. Basically he looks very similar to the Tako monster who is Usa Ranger chan's enemy in Daisy's favorite kid's show. This guy adores girls, but he doesn't seem to be able to attract them, for some pretty obvious reason.
