A Dewott kickboxer signed to the Reversal League Wrestling Foundation. He's not a wrestler, but the RLWF appreciates any and all combatants who are willing to help out their organization. In exchange for the job, he agreed to take on a name that Creative says was a combination of Rivers Cuomo, the concept of a river valley, and Vale Tudo. Embarassing is what he says it is.

Real name, Maenem Chen, he mainly trains to pay off his sibling's gacha debts and to find a life partner... at least, that's what his mom keeps asking him. Melanie's co-worker and confidant, he also acts as an informant for the Teambase within Nimbasa City because Barb pays him decently enough for that as a side-gig.
