From ADV:

Life is tough for lovesick teenagers! Meet Ee-Ji, a high school freshman suffering from—or is, perhaps, the cause of—an adolescent love triangle. Torn between two men, she is racked with grief over her own indecision. The first man in the running is Han-Kyul, a classmate since elementary school and Ee-Ji’s longtime lovable crush, or the safe bet. But, his competition is a far cry from his sweet and sensitive demeanor. Sae-Ryun is crude, offensive and constantly bullies Ee-Ji and her friends, but he has managed to catch her eye anyway. To make matters worse, these two contenders are best friends. This situation has the potential to explode into a sordid mess, but Ee-Ji will have to pick her favorite man first!

From Yen Press:

Kaede Takamura’s teenage life swerves to the brink of insanity when she comes face to face with her twin…or does she? Suzu is practically the mirror-image of Kaede — except for having cat ears and a tail and being far more well-endowed than Kaede thinks any teenager ought to be. But the Takamuras have no qualms about bringing this strange, happy-go-lucky catgirl into their home. With Suzu completely ignorant of the ways of modern society, it’s going to be a very long year for poor Kaede.

Once upon a time in a fantasy world plagued by war, a group of four brave souls challenge the source of all the evil. It seemed all was lost until one of the heroes defeated the enemy with a powerful spell. The four heroes were able to seal this great evil to be forgotten forever - or so they thought. The next scene in this story takes place years later with the children of those who sealed away the great evil. The sealing was accomplished by combining the power of two pendants. A foolish dark knight is somehow tricked into stealing the pendants, to break the seal that conceals the great evil. He defeated the heroes and kidnapped their children. With the two pendants in hand, he broke the great evil's seal. A remaining hero sends the children to another time so that, maybe, the world will have another chance. What will become of the children? How could they possibly defeat someone that their parents could only seal away? Who is the great evil and what is his purpose? Only time will tell as they venture on into several strange, yet familiar worlds.
