Takeshi Aiza

Takeshi Aiza is a formidable young pianist whose entire musical journey was ignited by a single, life-changing encounter with Kousei Arima's performance in childhood. Consumed by the singular ambition to surpass his rival, Takeshi spent the two years of Kousei's absence from the stage in relentless, disciplined practice — even turning down prestigious invitations from renowned overseas music academies. His candid personality and blazing devotion to the piano make him a magnetic presence, and once Kousei returns to competition, Takeshi emerges as the most compelling and consequential challenger standing in his path.
