Description
Lucia Yonazuki, alternatively rendered Luca Yonazuki, was orphaned by a car accident early in life. Placed with neglectful and greedy adoptive parents, his primary motivation became funding medical treatment for his chronically ill younger sister, Shiori Yonazuki, driving him to competitive success in Shadowverse. As a student at Obsidian Academy, he maintained exceptional academic and athletic records while developing overwhelming mastery of the card game, earning the moniker "Dark Prince" due to rumors of opponents quitting after facing him.
Initially projecting a cold, detached, and ruthlessly efficient demeanor, he reserved warmth solely for Shiori. Interactions with rivals and peers were aggressive when challenged. This isolation began shifting after encountering Hiro Ryugasaki; their evolving rivalry blossomed into genuine friendship. Their initial duel saw Yonazuki deliberately withhold a winning card, granting Hiro victory and signaling early recognition of Hiro's potential. This relationship challenged Yonazuki's assertion that Shadowverse was merely a financial tool. Confrontations with Hiro and intervention from Shiori forced him to acknowledge self-deception regarding his enjoyment of the game and his right to personal happiness despite Shiori's illness.
His competitive journey included significant tournaments. After defeating professional player Seiya Kibakura, he entered the National Tournament, ultimately losing to Hiro in the finals. Seeking funds for Shiori, he entered the Shadow Grand Prix, achieving Gold Rank before confronting Hiro again. During this period, he became one of seven individuals chosen to prevent global destruction by the Tree of Woe, undertaking expeditions into ruins containing Mythical Cards. A critical emotional turning point occurred confronting his sister, possessed by destructive entities. Shiori expressed distress over his excessive self-sacrifice harming his well-being, forcing him to openly admit his self-deception. This awakened his Mythical Card, enabling Shiori's rescue. Subsequent events involved battling destructive entities across the city and confronting allies like Mauro Abelard under negative influences. Drawn into the Tree of Woe with the other chosen individuals, he experienced an illusory world depicting a healthy life with Shiori before rejecting the fantasy. A subsequent duel within his Mythical Card's realm against Urias Formonde ended in victory and a commitment to securing genuine happiness for himself and Shiori.
Years later, into the Shadowverse Flame timeline, his circumstances and demeanor transformed. With Shiori's health recovered and financial burdens lifted, he transitioned into a noticeably kinder, more relaxed individual. Achieving unprecedented competitive success, he secured multiple championship titles, including the Shadowverse World Championship. This elevated status positioned him among the Seven Shadows, the world's elite players. Within this role, he demonstrated mentorship, notably challenging Itsuki Mitsutagawa at Shadowverse College to assess growth potential. After a victory where he acknowledged not employing full seriousness, he encouraged Itsuki to surpass perceived limitations. Later rematches revealed his connection to Hiro and the Seven Shadows' founding motivations, expressing hope Itsuki could reach Hiro's level. Though Itsuki lost, the duel reignited Yonazuki's long-absent excitement. He subsequently dueled Mikado Shirogane, initially showing disappointment at defensive play stemming from fear before acknowledging Mikado's eventual breakthrough.
During the Arc Ruler invasion of Nekome City, he collaborated with Hiro to defend against corrupted entities using the Nexa System, contacting allies to secure Mythical Cards. An ambush by enhanced entities nearly overwhelmed them until Eiji provided unexpected assistance. Following the Tree of Woe's revival and subsequent defeat, he and Shiori relocated to live with Hiro and his grandfather. His Bloodcraft deck specializes in Vengeance mechanics, activating powerful effects when defense falls at or below 10. Strategy involves self-damage tools, defense restoration, protective wards, and key cards like Dark Emperor, which possesses immunity to spell destruction and effect damage while destroying enemy followers under Vengeance. Deck refinements later incorporated cards such as Belphegor for automatic Vengeance activation and Vermillion Killer to enhance Dark Emperor's capabilities.
