Hydra: When Ryuu transfers to Hitomi's school, he leaves an immediate impression on him. Curious about rumours of a full-scale tattoo on Ryuu's back, Hitomi starts getting closer to him. Before long, the friendship and fascination Hitomi feels for Ryuu start developing into more, but before he has a chance to come to terms with his feelings, Hikaru appears on the scene.... and he has his eyes set on Hitomi.
Lovers and Souls: Tooru is a young model who becomes a gay prostitute because he doesn't care enough about himself. However, he's starting to fall for his sempai. Can Matsouko save him?
Rules: Yuki, a high school student, is confused about his sexuality. He meets Hikaru in the sleazy gay district, and sleeps with him. They begin to play at being lovers, but Konoe's heart belongs to Atori, his friend and classmate. Can Yuki come to terms with his sexuality and reveal his feelings to Atori, and where do Hikaru's true feelings lie?
