Senjome is a parody character based on Chazz Princeton, who is known as Manjoume in the Japanese version.
The name "Senjome" (千条目) appears to be a pun on Manjoume (万丈目), which is Chazz Princeton's family name in the Japanese version. The 万 (man) in 万丈目 means "ten thousand", a fact which is referenced in his catch phrase. In the name "Senjome", 万 has been replaced by 千 (sen), meaning "thousand".
Senjome appears as an unlockable character in the Yu-Gi-Oh! GX Tag Force games.
In Yu-Gi-Oh! GX Tag Force, Senjome appears at the Obelisk Blue dorm once the player has completed the game with at least three of the seven originally avaiable characters. He asks for the player's aide in his, Sironos' and Sanzyudai Yuki's feud against Emperor.Umiuma and the rest of UmiumaCorp. Should the player agree, after winning a Tag Duel with Senjome as their partner, he and his companions can be selected as partners for the Tag Force tournament.
Tag Force 2
In Yu-Gi-Oh! GX Tag Force 2, Senjome can appear in a special story event at the Ra Yellow dorm, partnered with Inoso, if either Syrus or Tyranno has been defeated in duels at least 15 times. After defeating them, both Inoso and Senjome can be selected as tag partners.
