Blackmailed by the criminal organization FUG, Twenty-Fifth Bam, masquerading as Jyu Viole Grace, must continue to conceal his identity and prevail in the Workshop Battle that pits him against his former allies. Among them are his old friend Khun Aguero Agnes and his new teammate Ja Wangnan, who were promised by FUG that Viole would be returned to them if they win the competition.

However, as various factions start putting their secret plans into motion, the situation on the battlefield becomes increasingly convoluted. If Wangnan and Aguero Agnes want to have a chance to free Viole from FUG's harmful influence, they must unite to uncover the darkness of the Workshop before it is too late.
