Kalin Kessler, known as
Kyosuke Kiryu in the Japanese version, was a former member of the
Dark Signers and was a resident of
Satisfaction Town.
During his time as a Dark Signer, Kalin wore the black robe of the Dark Signers that was accented with blue stripes. His dark mark was the Giant. He had extreme hatred toward
Yusei Fudo and his previous team (
The Enforcers), but later forgave them after he found out the truth from his loss to Yusei. He was brought back to life after Goodwin's defeat. He was last seen in
Crash Town, where Kalin attempted suicide by Dueling in order to atone for his wrongdoing, only to be forgiven for them by his former teammates,
Yusei Fudo,
Jack Atlas and
Crow Hogan. He later stayed behind to help rebuild the town along with
West and
Nico, which was later renamed Satisfaction Town to cherish his team's honor.
