OVA
Description
Ryū, a 12-year-old child prodigy serving at Wistal Royal Pharmacy, sports dark chestnut hair and aqua-blue eyes. His wardrobe features baggy, youth-appropriate attire accented by a scarf, later replaced by a functional winter poncho in Lilias. A pragmatic decision to trim his hair shorter marks a visible shift toward practicality.

Possessing a calm maturity beyond his years, Ryū’s intense focus on pharmacological studies—especially poisonous plant interactions—earns him inadvertent adult treatment, fostering social detachment. Struggling to navigate emotional exchanges and burdened by rumors about his toxicological interests, his reserved nature initially distances peers. Yet beneath this lies a persistent drive to strengthen both mind and body, voiced through frequent wishes to accelerate his growth.

Plucked early from ordinary life for his genius, Ryū’s sheltered upbringing in Clarines’ capital revolved around work, devoid of childhood companionships. His dynamic with Shirayuki begins when she joins the palace pharmacists, catalyzing his social evolution. Collaborating on Olin Maris research in Lilias, he tentatively cultivates trust and communication skills.

The Lilias chapter sparks profound change: friendship with local boy Kirito hones Ryū’s social awareness, while thawing reserve allows warmer colleague interactions and more open dialogue. Physical growing pains herald a height surge, paralleling his adolescent transition.

Garak Gazelt, his mentor, provides paternal guidance, while Shirayuki’s influence softens his relational hesitations. Bonds with Obi and Zen ease his integration into social circles, though early encounters with Zen reveal discomfort at being typecast as prematurely serious.

Notable quirks include limited stamina, culinary ineptitude, and a tendency to nap beneath his desk during distractions—a habit Shirayuki once replicated experimentally. He favors the crimson-petaled Yura Shigure plant for its beauty, coincidentally echoing his friend’s hair hue.

Post-Olin Maris resolution, Ryū opts to stay in Lilias with Shirayuki and Obi, dedicating himself to disseminating safe Phostyrias variants. This choice underscores his evolving prioritization of teamwork and ongoing self-development over solitary pursuits.
