Claudio Serafino, leader of the Sirius Marksmen, collaborated with Heihachi against his exorcist organization to confront Jin and Kazuya Mishima. Learning of Ling Xiaoyu’s search for Jin, he approached her, intending to use her in his mission. As a member of the “purifying blue flame” lineage, Claudio was determined to defeat Devil at any cost.
Betrayed by Heihachi, Claudio lost credibility, leading to defections within the organization. Xiaoyu’s trust left a profound impact, prompting Claudio to confess and apologize for his actions. He pledged to assist Xiaoyu in finding Jin. However, if Jin succumbed to the Devil gene, Claudio, prepared to do what’s necessary, unleashed forbidden exorcism arts, risking his own lifeforce.
