Yume no Akichi

Renei experiences recurring dreams of "Ku's World," a realm under Mount Babiranma populated by creatures like Nagizari, God, Rey, and teppas. She suspects her deceased brother, who is struggling with his identity, and her friend who died by suicide and has since returned, may be there. As she grapples with the meaning of life, her reality becomes increasingly unstable. The beings from "Ku's World" start appearing to her and urging her to join them, blurring the line between dream and nightmare. The mystery of Mount Babiranma remains unsolved, and the question lingers whether they will survive what lies ahead.
