Nekota Kuniboshi (aka Niboshi) is known for his perversion. All the
girls at his school despise him, except for Yumeno Shizuku. Shizuku is
nice, smart, and the prettiest girl. The fact that she talks to him
confuses Niboshi to no end, and he has no idea how to deal with it.
While Shizuku is away from her desk, Niboshi finds a half empty water
bottle. He drinks out of it and proceeds to stalk Shizuku while she
practices her gymnastics. As he watches her practice, he wishes that he
could turn into the suit that she is wearing. To his surprise, his wish
comes true! Now, he finds out that the liquid he drank from the water
bottle was in fact, a chemical created by Shizuku's father that allows
him to turn into any object he wishes. An odd experimental relationship
begins between Niboshi and Shizuku.
