Real Name: Shimazu Ryosuke Gender: Male Born: 1850 Died: 1881 Age: 31 at time of death (176 as of 2026, but stopped aging due to being non-human) Cause of Death: Excessive bleeding (from sword wounds) Nationality: Japanese Species: Non-human Height: 180cm Weight: 60kg Personality: Cool and grumpy, but slightly introverted. He was a Japanese warrior in his past life. He takes care of others even while complaining and is surprisingly eccentric. He has medium-length black hair, dark skin, and only eyes—no mouth or nose. He prefers comfortable clothes like long-sleeved cotton shirts and sweatpants. He loves beer. He is surprisingly strong and uses a katana. He never attacks first unless provoked. Surprisingly, he does not speak in a historical sageuk tone. He prefers to be called "Shimazu" or "Mr. Shimazu" rather than his full name. Perhaps because he is immature, he speaks like a child compared to his actual age.
