Hello World

A shy teen meets his future self to rewrite a lover's doomed fate in neon‑lit Kyoto.

Set in a hyper‑modern Kyoto of 2027, the story follows Naomi Katagaki, a painfully shy high‑schooler whose world revolves around textbooks and quiet corners. Across the hallway sits Ruri Ichigyou, a blunt, ice‑cold reader whose sharp tongue keeps most people at arm’s length. Naomi admires her from afar, too nervous to bridge the gap despite their shared love of literature. One evening, a scarlet aurora flickers across the sky, and a three‑legged crow swoops down, delivering a bewildering message: a hooded stranger claiming to be Naomi ten years older. The future Naomi warns that a tragic accident will soon claim Ruri’s life unless the present‑day version can alter the chain of events that lead to their romance. Skeptical yet desperate, Naomi follows his older self’s cryptic instructions, gradually nudging himself into Ruri’s world. As their connection deepens, he must balance the fragile line between genuine affection and a mission born of desperation, questioning whether love can truly rewrite destiny. The film blends earnest drama with speculative sci‑fi, using the neon‑lit backdrop of a technologically advanced Kyoto to explore themes of fate, self‑determination, and the bittersweet courage required to reach out for someone who seems untouchable.

A sci-fi romance where a boy receives help from his future self to save his classmate from a fatal accident, blending simulation theory with time-loop stakes. The film focuses on emotional connection and sacrifice rather than action, with a bittersweet tone that may resonate strongly with teens but could upset sensitive viewers due to the persistent threat of a main character's death.
