Chibi Yūto is the twelve-year-old manifestation of protagonist Yūto Matsubara. He materializes inside the cockpit of the "Time Driver" robot, brought forth by the power of dreams. This younger self embodies the protagonist's childhood, starkly contrasting with the adult Yūto Matsubara's disillusionment over his career and personal aspirations. Chibi Yūto's appearance compels the adult protagonist to confront his current dissatisfaction and the dreams he abandoned, especially concerning his childhood sweetheart Ai. He serves as a physical manifestation of the protagonist's lost ambitions and unresolved emotional state, directly challenging the adult's pervasive sense of resignation and hollow daily existence.
