Dororonpa!(1991)

Dororonpa! is a supernatural comedy series following Komachi, a ghost who died during Japan's Meiji Era and has drifted through the world for over a century. When Komachi materializes in the bedroom of a young girl named Anko, the two form an unlikely friendship that pulls them into a whirlwind of paranormal misadventures. Together they encounter mischievous spirits, troublesome demons, and other supernatural beings that test their bond and drag them into increasingly bizarre situations. The series blends humor with ghostly encounters, creating a lighthearted take on the spirit world where Komachi's century-old perspective clashes with Anko's modern sensibilities. Their adventures reveal both the comedic and touching sides of existing between the living and supernatural realms.
