Mitch, known as Micchan in the Japanese version, is a boy living under Martha's care.
While dining with the Signers, he enjoys Trudge's stew. The meal is interrupted by the appearance of the Dark Signer, Roman Goodwin.
Yusei orders Jack to take the children to safety while he Duels Roman. However Mitch, along with Taka and John stay back to see if they can get revenge on the Dark Signers for what they did to Crow.
John and Mitch get separated from Taka and get close to Yusei's Duel. Roman Summons his Earthbound Immortal, nearly sacrificing John and Mitch in the process. However Jack appears and forms a protection bubble with his Signer powers, thus saving them.
