Biography
Years before the current storyline, Blister's best friend, Kyuji, who was severely injured in a Duel Runner crash. The only remaining memento of his friend is Kyuji's scorched "Machiners Sniper" card from the crash. Ironically, Kyuji could have escaped unscathed, but he went back in for the "Machiners Sniper" and was badly burned. This incident caused Blister to develop a grim outlook on Duel Monsters and on friendship in general.

Following Bolt Tanner's instructions, Yusei Fudo seeks Blister's help in recovering his D-Wheel and deck from the Securities. Saiga ridicules him for planning to sneak into the Security's storage to steal it back, by telling him it's the same as getting caught.

After Yusei assures Blister that Kyuji has no aversion to Blister after that day, he returns the favor by stalling Trudge after Trudge chases Yusei following Yusei's break-in. Blister manages to avoid capture, and later springs Himuro and Yanagi from prison to prepare for the Fortune Cup.

Before the Fortune Cup, Yusei tells Blister of his captured friends from Satellite, which Lazar uses to blackmail him into entering, and Blister tells Yusei that he will call in a favor from an old friend to sneak into Satellite and check on them.
