Summary
As a child, Rion saw an uncensored tape that showed demons possessing little boys who would later grow up to be demons and attack young girls. From then on she was convinced that young boys were angels who would turn into villainous devils when they got older. Now that Rion has grown into a pretty young girl, she only has eyes for little boys and avoids “devils” at all costs. She even goes to an all-girl school in order to avoid men.
The manga starts as her father – “the big devil” – is coming home from being out of town. Rion goes to buy groceries for dinner and on her way home she is attacked by a scruffy-looking vagrant who is demanding food. Luckily, a handsome man stops the attack, but Rion thinks it’s a ruse perpetrated by the two of them to get to her. So she runs home and hurries to the elevator, but a man jumps in the elevator with her. So she runs away from him and takes the stairs all the way to the top of the complex, but on the way she runs into a gorgeous young boy named Tenshi who looks exactly like her first love. She falls for him instantly, but he seems uninterested.
When Rion makes it to her room, the scruffy vagrant, the handsome do-gooder, and the man from the elevator are all there waiting for her! It turns out that Rion’s father gathered them all together and they are all now her fiance. And over the next few days she is supposed to choose one of them to marry, whether she likes it or not. Now all she wants to do is be with Tenshi, but these beautiful men keep throwing themselves at her. It certainly doesn’t help when the big devil gives all of them a key to her room so they can drop by whenever they want. Oh, what is a girl to do?
Characters
Rion Ryuzaki
A beautiful, hot-tempered girl traumatized by a glimpse of an adult video when she was younger, Rion is terrified of men. Much to the disappointment of all the boys her age, she only likes younger guys. After her adopted father arranged her to pick three boys as her fiancé, Rion slowly begins to open up to them. She falls in love with Tenshi Kogai, a young, so to seem, boy living in the same building she lives in.
Soon, Rion learns that she made a contract with her adopted father, who was part of a clan of Devils that cannot bear children, injecting Devil DNA into her bloodstream. The devil part of her, goes to sleep within Rion until her sixteenth birthday draws near. Rion's other persona is more seductive and aggressive than the real Rion, along with her cat-slits eyes.
After Tenshi lashed out at her, thinking that he was stuck in his child form because of her, Rion went to confront her father. In an agreement, Rion was to have sex with one of her fiancés, he will returned Tenshi back to his true self. Scared, Rion told Tenshi what happened and then went off to ask Somi, one of her fiancés, to sleep with her. Before anything could happen, Tenshi broke it up, and ask Rion to come back to him.
Soon, the memories from his past restored him back to his original self. Somi still intended to bed with Rion and the two boys got into a fight. After trying to figure out how to cure them of the Devil and Angels DNA, Rion concluded that the only way to achieve this, was to have sex with one of them.
Not wanting Rion to waste her first time of one of fiancés, he dragged Rion to the room to sleep with her. Rion blacked out and her other persona took over. Tenshi managed to switched Rion back to her old self after telling the Devil Rion that he would still sleep with her because Rion is still Rion and frightening the real Rion, they figured out to stop the shifts in her and her fiancés was to have someone they love talk them back to themselves.
Hoping her fiancés would give up on her after learning this, Somi, Fuuya, and Koki was even more determined to win her over, much to her and Tenshi's dismay.
