Description
Subaru Hoshiyomi, Aibo Academy's Ace of Study, dominates nationwide tests with exceptional academic prowess. His platinum blonde spiked hair, gold-trimmed grey coat featuring white and cyan accents and constellation-patterned cuffs, and bright yellow star-shaped forehead birthmark make him visually distinct. Initially stoic and reserved, he projects an "invisible wall" deterring approach, yet privately enjoys comedic RanGa Channel content and occasional laughter.
Intensely focused with a strong moral compass, Subaru engages only in challenging Buddyfights, dedicating significant mental energy to strategizing mid-battle. He defines righteousness as choosing freely without external pressure but reconsiders if proven wrong. This drives his strength pursuit—not for victory alone, but to uphold ideals. After losing to Kei Jinguji, he analyzed his deck for hours to grow stronger.
His deepest bond is with Buddy Skyseer Dragon Cross Astrologia, sharing mutual concern and silent understanding where Cross intuits Subaru's unspoken feelings. Subaru evolves in relationships: initially dismissing Yuga Mikado as unskilled, he later acknowledges Yuga as a rival after their matches. Following a loss, he fakes defection to Ranma’s side to expose Vanity Husk to Buddy Police while trying to redirect Ranma. Mel Yumegatari intensely admires him, though he remains oblivious.
In Buddyfights, Subaru wields a Star Dragon World deck centered on Astrodragons and signature card Skyseer Ardent Dragon Cross Farnese Astrologia. His strategy completes the Galaxy Formation—requiring a Center monster, Left/Right monster, and equipped item—granting Penetrate and +1 Critical for aggressive plays capped by Impact card Tri-Star Decision. As Ace of Study, he preemptively studies opponents' decks to integrate countermeasures. After losing to Seiji Kido’s Oppress deck, he modified his deck for Galaxy Formation flexibility with either Left or Right monsters.
His resilience and tactical growth define his development. After the Jinguji loss, he accepted an interdimensional duel against Ades for a fading Dragod’s power. There, he defended his righteousness philosophy against Ades’s claim that power distorts others' paths, reaffirming self-determined choices. His record includes early wins against Yuga and Mel; losses to Jinguji, Seiji Kido, Ranma Kakogawa, and Masato Rikuo; and later victories against Seiji and others. Cross’s evolution into Skyseer Ardent Dragon enhances Subaru’s deck versatility and power. In the Legends storyline, his Ades confrontation cemented his resolve to wield strength responsibly while honoring his ideals.
