Shintarou Tokumitsu lives a typical high‑school routine in a cramped studio apartment that he alone occupies. Everything shifts one dawn when an unusual sight appears on his balcony—a celestial being from Heaven. The gentle, pure‑hearted girl Towa has been dispatched by God to Earth to observe human behavior and culture. She quickly bonds with Shintarou, who ultimately permits her to stay in his home. Yet the modest dwelling offers scant personal space and privacy, making it hard to conceal Towa"s true nature from outsiders. As Shintarou adjusts to this new coexistence, his interactions with other girls could further entangle the situation. The bustling streets outside seem indifferent to the extraordinary event unfolding within his modest walls.
