This is the first quarter of the story.
Litthenen Y follows the story of a girl stolen from her life as an infant, only to discover she has demonic as well as angelic power hidden within her soul. The name Liltaia is created fron two names that have conflicting meanings, Lillith which is demonic, and Gaia which is Earth-oriented, representing good. Liltaia's powers are hidden within her and she has no knowledge of them, but the demon queen that took her always tells her she is very "special and unique." The demon queen is known as Siele C'euron (see-elle surhn), ruler of the southern region of Reilaile known as Loielis, north of Loielis is the blue city, Alphaetia.
Siele has told Liltaia that she is her real mother and the only one who cares for her, to the people in Loielis under Siele's control Liltaia is the Crystalline Princess, crystalline like stone, unable to move freely. Liltaia is fourteen now and wondering why Siele still looks like she did ten years ago, while all of the other people have aged. As the days go on Liltaia finds Siele increasingly strange, she has an odd feeling that Siele isn't her mother but will not mention the feeling to Siele. Siele picks up on Liltaia's change of attitude and orders her to be secretly watched by member of the Elite Hell Guard.
Liltaia's best friend, Aaila, sees one of the guards spying on Liltaia and tells her about it, from then on Liltaia's own instincts are confirmed. Liltaia packs her bags and takes Aaila with her in fear of her well-being and they set off together. Having absolutely no idea where their adventure will lead them, they wind up getting lost in the dense forest with no weapons, they run through the forest and end up in a small town that looks deserted. On closer examination they find that tthe townspeople are in hiding from the creatures who try to lure them out of their homes for slaughter. Liltaia decides to help the people, they give her their best weapons and armor, she waits for the creatures to come back to the town. When they do she eradicates them and the town celebrates her victory, the morning arrives and Liltaia and Aaila are on their way with a tearful goodbye, Aaila suggests they should go to the north and see what its like, Liltaia agrees. Although they must travel through the barriers Siele has summoned, that alone makes it harder to escape, since they must take detours and stay away from the main districts.
Siele figures that they will attempt taking a detour, so she sets up barriers that only Hell Magic can break, knowing that Liltaia cannot summon her Green Flame yet, she suspects this will keep them from leaving Loielis. Little does Siele know, Liltaia's Green Flame is awakened is dire situations, when Aaila and Liltaia arrive at the West Barrier they find themselves surrounded by The 1st Quarter Hell Guard, they grab Aaila and pin Liltaia to the ground, just as they are about to kill Aaila, green flames engulf all of the guards and they turn to ashes. Liltaia faints from overexertion and Aaila carries her body into the woods to hide.
Meanwhile, Siele is alerted that piles of ashes were found by the West Barrier, Siele knows that this means Liltaia's Hell Magic has awakened. This shocks Siele as she suspected Liltaia couldn't summon her flames without proper teaching and guidance. In the woods, Liltaia awakens and is told by Aaila what happened, then Liltaia tells Aaila of the story she read in the 3rd floor library in Siele's Castle. The story told of a girl child born with the powers of the Heavens as well as tthe powers of the Infernal Abyss. Aaila realizes that the story spoke of Liltaia, but Liltaia remembers that the story also had key parts in it speaking of how the girl was to activate her powers. Aaila and Liltaia decide that they must get the book, and so their true adventures start...
