Guan Yi is an 18‑year‑old boy who has been reborn on Mist Star. He is portrayed as a smart, diligent, and filial son, always obedient to his parents and teachers. He secretly signs up as a Secret Realm explorer instead of attending the National University of Defense Technology, which shocks his teacher and friends. He possesses a mysterious plan called “Secret Realm Changes Fate, Helping Hands to Realize Dreams” that allows him to enter other worlds for training. Determined and resourceful, he enters the One Piece world as a volunteer, working as a dock laborer in Xixikono Town while secretly practicing Xing Yi Quan. He shows strong work ethics and physical prowess, and is not afraid to stand up against local gangs like the Wild Boar Gang. His father is suspected of colluding with the Demon Race, which drives Guan Yi to become a Secret Mark warrior quickly.
