Rom, a hot-blooded leopard Myumon, commands attention with his towering 186cm frame, lean muscles, and striking features—dark red sclerae, dark blue pupils, and spiked hair. His bold style includes a leopard-print vest, spiked wristbands, and a necklace, transforming across forms: energy shifts his vest to grey, soldier mode adds a utilitarian green vest with pockets, and Wild Soldier drapes a camo jacket like a cape, paired with an eyepatch. As ShinganCrimsonZ’s drummer, he wields the "Skull Jaguar" drum kit and ignites his fists in flames during combat, earning the moniker "Legend of Violence" from bandmate Yaiba.

A natural leader, Rom rallies his bandmates with fiery speeches and decisive actions, driven to etch their legacy into music history. His past as co-founder of the disbanded Amatelast with Shu☆Zo fuels a rivalry between their new groups, ShinganCrimsonZ and Trichronika, underscoring his focus on legacy. Beyond the stage, he juggles an office job and wanderlust, his charisma effortlessly drawing allies like Maple Arisugawa, whom he met at Zakuro Fishery tavern, sparking the band’s creation.

Despite his wild persona, Rom anchors the group, mediating conflicts and curbing recklessness with a grounded demeanor. His middle-school drumming roots and onstage habit of shedding layers to flaunt his physique contrast his disciplined dual life. The character song "The Real Reason" echoes his journey, blending personal ambition and collective fire in a narrative of passion and balance.
