Absolute Boy(2005)

Absolute Boy follows Ayumu Aizawa, a teenager whose childhood memories remain stubbornly blank—not from amnesia, but from something deeper. Reluctant to reconnect with his estranged father after four years apart, Ayumu is bribed with a mountain bicycle to spend the summer in Tana, a quiet rural town outside Tokyo. What begins as a reluctant escape becomes something far stranger. Upon arrival, Ayumu encounters inexplicable phenomena: a mysterious boy named Wakkun who inhabits an enchanted forest, and luminous orbs drifting across the night sky. As these supernatural events unfold, fragments of Ayumu's forgotten past begin to surface, pulling him toward answers he never knew he was seeking.
