Ryuutarou Mine

4th-year Violin student. His father owns a Chinese restaurant "Uraken" right next to the university. He is something of a prima donna whose violin technique is seen by himself to be deeply personal but by others to be simply sloppy. He sees Chiaki as a rival for attention and tries hard to compete with his "Princely" image of him. He likes Nodame for her free-spirited ways. He is the concertmaster of the S Orchestra conducted by Chiaki, and a violinist in the R☆S Orchestra. He is also the one who thought that performing like Jimi Hendrix, and adding a touch of 'rock' would give quality despite that it looks dumb in an original orchestra (as stated by Chiaki).

He is currently dating Kiyora Miki.
