An enlarged image of this monster's face encompasses the background of this card's artwork. This is a classic trope in fighting video games, which is present in the artworks of all "Vanquish Soul" monsters, which are based on the same genre.
The kanji on this monster's eyepatch (柔) is the "ju" in "jujitsu", meaning "soft", "flexible", or "yielding." Appropriately, jujitsu itself is a martial art that relies on weaponizing these qualities to use the opponent's strength against them.
