Ayumu is the main character of the story. It is him who discovers Wakkun in the woods and befriends the fairies, Dosshiru and Shisshin. He is one of the few characters to make active appearance in both parts of the series, the Summer Arc and the Winter Arc. During the summer he is the main character and is staying at his father's veterinary office in Tana. During winter he is studying in Yokohama.

Aizawa Ayumu is a young boy, who is sent to a small town called Tana to live with his father for a while. Even though he doesn't want to go, he agrees to do so when his mother offers him a mountain bike. Ayumu used to live in Tana before, and now his memories of the time are shrouded in mystery - apparently something happened when he was a child. Enter Miku, a young girl who knows more than she tells, weird glowing lights floating around, reflections of UFOish objects in the eyes of cats and dogs, a nosy female announcer, a forest with a mysterious past, and a weird boy called Wakkun, who wears the clothes Ayumu used to when he was a child, and you get the world of Zettai Shonen, where mysteries remain mysteries amidst a slow, normal, everyday life.
