Yamanaka (Laughter Mask)

Laughter Mask「笑い仮面, Warai Kamen」, voiced by Daisuke Nakamura and Wayne Grayson, is a Duel Monster Spirit fused with Yamanaka, a Ra Yellow student. It Dueled Axel Brodie and left Yamanaka's body when it was defeated.

Laughter's strategy relied on the synergy between "Fool Clown" and "Rough Exploder".
