“‘Yubel’, having sworn eternal love in a past life, was reincarnated from an unsightly dragon into a heroic form. The card used by [Judai/Jaden] inflicts damage according to the ATK of the opponent’s monster, and some elements of its dragon forms can also be seen, and I thought these may form a connection with its past life. I requested this illustration keeping these things in mind. From the very beginning, I already wanted to incorporate [the concept that] ‘Super Polymerization’ is an unbreakable bond in the card design, but I remember I got very excited when I realized that it is actually possible to fuse 12 monsters.”
