Biography
Summoned by Don Thousand after Number 96's defeat, Semimaru and the other members of the Fearsome Four returned to Earth. Semimaru began to attack other duelists and stole their memories, including the Super Secret Number Cards Investigation Club, while Mr. Heartland lured Yuma to their hideout. Heartland told Yuma that in exchange for the "Numbers", he would restore the memories of the Numbers Club, while erasing those relating to Astral. Yuma refused, resulting in Heartland attacking him with a swarm of insects. After Trey saved Yuma from the attack, Semimaru challenged both of them to a Duel. Before the Duel started, Heartland activated a device that halved Yuma's and Trey's Life Points, while doubling Semimaru's at the same time. Despite the large Life Point disadvantage, Yuma and Trey managed to defeat Semimaru with a combination of "Number 6: Chronomaly Atlandis", "Quick Reservation Reward" and "Double or Nothing!".

Deck
Semimaru uses a "Cicada" Deck, primarily focused on Swarm and Defensive tactics, focused around "Number 3: Hell Cicada King - Locust King".
