Following an apparent death and separation from his teammates, Twenty-Fifth Baam was forcibly recruited by FUG and adopted the alias Jue Viole Grace. This identity positioned him as a Slayer Candidate destined to challenge King Jahad. The name combines "Grace" from his mother Arlen Grace and "Viole" from his father V, revealed by Princess Garam Zahard and confirmed by FUG leader Grace Mirchea Luslec, who once served under V. On the 30th Floor during the Workshop Battle, Jue Viole Grace displayed long black hair in a ponytail and distinctive black FUG robes, an aesthetic curated by mentor Ha Jinsung to mirror his feared status and contrast his simpler past attire. Betrayed by Rachel and coerced by FUG through threats against friends, he maintained a cold, distant demeanor. Yet beneath this restraint, he harbored fierce protectiveness toward allies and internal conflict over his role as FUG's weapon. Compelled by FUG to enter the Workshop Battle—a five-yearly competitive event—Jue Viole Grace secretly sought reunion with original teammates Khun Aguero Agnis and Rak Wraithraiser. During stages like the preliminary "One Shot Opportunity," where Regulars competed to board the floating fortress Archimedes, his notoriety as a Slayer Candidate made him a target for adversaries like Varagarv. He dispatched foes effortlessly using techniques such as the precision-based Floral Butterfly Piercing and high-speed Blue Oar. His actions drew Princess Endorsi Jahad, who manipulated her team to confront him. Their reunion ignited when she intercepted a combat robot attacking him, foreshadowing further clashes. He also acquired the Thorn fragment, a weapon forged from the remains of the Irregular Enryu, amplifying his power for future conflicts. His relationships balanced tension and loyalty. Though initially isolated from Khun and Rak, their collaboration later aided his escape from FUG's direct control. He formed reluctant bonds with Team Sweet and Sour, including Ja Wangnan, who accepted him despite his FUG ties. Encounters with Endorsi stirred unresolved emotions, though their interactions remained ambiguous. Beyond the Workshop Battle, Jue Viole Grace confronted his origins as Arlene Grace and V's son, learning of his resurrection by an "Outside God" and destiny to challenge Jahad. This shifted his focus from pursuing Rachel to seeking a tyranny-free "paradise." In later arcs like the Hell Train and Nest battles, he mastered the Thorn, defeated High Rankers including White, and navigated conflicts instigated by Great Families. Within the Hidden Floor, a digital echo named "Data Viole" manifested as Baam's sworn enemy, replicating his Workshop Battle-era appearance and combat style but lacking the Thorn, embodying his internal struggles.
