Gondwana no Nemuri

During a routine class trip to a museum, a student named Kasama finds his attention drawn to Takagi, a quiet and withdrawn classmate who rarely interacts with others. Takagi’s isolated nature has always set him apart, but it is during this seemingly ordinary school excursion that Kasama begins to see his peer in an entirely new light. The familiar setting of the museum soon gives way to something inexplicable when Takagi steps through a peculiar, mysteriously glowing door hidden within the building. Driven by curiosity, Kasama follows and makes a startling discovery: Takagi possesses the ability to perceive a strange phenomenon referred to only as "it." Realizing that his quiet classmate shares this uncanny vision shatters the mundane reality of the field trip and awakens a profound fascination within Kasama. No longer just another distant face in the classroom, Takagi becomes the center of a compelling mystery. This shared secret bridges the gap between the two boys, transforming Kasama’s passing observation into a deep, driving interest as he seeks to understand both the enigmatic doorway and the silent classmate who dared to walk through it.
