The Super Genius

Trudge and Mina invite Yusei, Jack and Crow for a fancy dinner, albeit with a motive. They want them to look after Bruno, an amnesiac who recently washed up onto New Domino City. Whilst they initially refuse, they soon discover he is an extremely talented mechanic. Yusei becomes particularly interested in him, as he could help build the engine he needs to perfect Accel Synchro. However, as he spends more time with him, his friends start to get a bit jealous. Yusei and Bruno manage to complete the program needed for his new engine, but it is stolen overnight. Finding a fingerprint on a cup ramen packet, they decide to hack into the Security network to find the culprit, having to complete a puzzle duel in order to gain access. Jack and Crow have trouble going up against Mirror Force, but Bruno uses his intuition to figure out the correct solution. They discover that the matching fingerprint belongs to Lazar.
