In the story of Un-Go, Shinjūrō Yūki (voiced by Ryo Katsuji) and Inga (voiced by Aki Toyosaki) work together to solve mysteries in a near future timeline. The story is based on the works of Ango Sakaguchi (Aoi Bungaku Series' "In the Forest, Under Cherries in Full Bloom"), a post-World War II Japanese novel and essayist. I have great expectactions for this one since Mizushima and studio BONES worked together for Fullmetal Alchemist, and the time travel theme is also there.
