After Yusuke Fujiwara's parents died, the Duel Spirit Honest appeared to Yusuke and promised to protect him.
After Yusuke's disappearance in the Abandoned Dorm, Honest took on the appearance of Yusuke and continued to attend Duel Academy in his place.
Honest became targeted by Trueman, but was rescued by Jaden Yuki. In an attempt to protect his identity, Honest attempted to hypnotize Jaden into thinking they had been long time friends. Jaden managed to prevent himself being hypnotized, using power he obtained from Yubel. Honest fled after Jaden asked who he was.
While researching information on Yusuke Fujiwara, Axel Brodie revealed there no student enrolled in Duel Academy under this name, but the name was listed under students who disappeared in the Abandoned Dorm.
He later reappeared in the Abandoned Dorm's Duel Arena, where Jaden identified him as Honest. Honest was destroyed by Trueman as he sacrificed himself to protect Jaden. After his sacrifice, Jaden received the "Honest" card to use in his third rematch against Trueman.
Honest later appeared to the Nightshroud possessed Yusuke and tried to convince Yusuke to remember the past, when he had friends. Yusuke denied having memory of Honest and such events.
After Jaden defeated Yusuke, Honest exorcised Nightshroud from Yusuke's body. Jaden also returned the "Honest" card to its rightful owner.
While in disguise as Yusuke, Honest possessed a variety of supernatural powers like teleportation, starting fires with his mind, sensing darkness, and emitting shock waves that force opponents back. He also had the power to hypnotize people and alter memories, which he used to trick students that he is a student at Duel Academy.
