デビデビ, Devil & Devil, Devil Devil
Above the Earth, there is a continuous battle between angels and devils. One devil in particular, Sword, has it in for a certain angel, Ios. In their 101st fight together, both are severely wounded. Not only that, but their clashing power causes the two to fall to earth. By chance, Sword finds a beaten, unconscious teenage boy nearby, and he is able to take over the human's body to save his own life.Some time later, Sword awakens in the hospital, briefly confused about his whereabouts. The father of the body he possessed enters the room, extremely happy to see his boy Souma alive. Then the older twin brother shows up. Immediately, Sword recognizes his enemy's energy. Also nearly dead, Ios had joined with Kanna's body. Sword goes to attack Ios, but quickly realizes that the body is far weaker than his demon form, especially from being recently beaten to hell.

たまごのきみ。, 雞蛋少女, 鸡蛋少女, Tamago no Kimi, The Egg Yolk, You're Egg!
The planet of Salami is almost identical to planet Earth. Judging from the appearance, there's nothing different from Earth... Except... The sense of beauty is VERY different. Aimi is an orphan living with her step-mother and step-sisters, and she is what we consider as being beautiful, but what THEY consider as ugly. Yet, that doesn't end the story. Just by an accident, Aimi stumbles upon Earth and meets Kyou Naruse, a self-centered person or someone called.... "The Narcissist." Our very own Cinderella Story... [except for the fact that Aimi's sense of beauty is ALSO different] or not.
