Takumi Fuwa

Fuwa initially appears calm, experienced, and deeply invested in classical music. His long professional relationship with Kazuki reflects decades spent around high-level performers and carefully maintained instruments.

He takes considerable pride in his abilities as a tuner. Music is not simply employment to him; his sense of professional worth is strongly tied to his ability to hear and correct extremely subtle differences in pitch.

That pride has hardened into resentment, leaving him increasingly bitter about changes in Kazuki's career and his own diminishing role within it.

Fuwa is an expert piano tuner with highly developed auditory perception and extensive knowledge of musical instruments.

As director of Domoto Concert Hall, he also understands the building's design, pipe organ, rehearsal facilities, and technical infrastructure.

Fuwa uses his knowledge of the hall and musical equipment to plan sophisticated attacks while attempting to conceal their common purpose.

Fuwa appears as one of the senior figures responsible for preparing Domoto Concert Hall's inaugural performance. Police question him as attacks begin targeting musicians associated with the venue.

His long friendship with Kazuki and history as the pianist's tuner gradually become important to Conan's reconstruction of the case.

Fuwa is revealed as the person orchestrating the attacks. His motives combine resentment toward Kazuki with anger over the death of Hikaru Soma, whose fatal accident Fuwa connects to musicians associated with the hall.

He attempts to destroy the concert hall during its opening performance, but Conan and the police expose his plan before he can complete it.

Kazuki Doumoto is Fuwa's longtime friend and former principal client. Kazuki's abandonment of the piano leaves Fuwa feeling that his life's work has been discarded.

Genya Doumoto is Kazuki's son and one of the professional musicians within Fuwa's circle.

Reiko Akiba, Rara Chigusa, and Shion Yamane are performers associated with the hall Fuwa directs.

Conan Edogawa investigates Fuwa's connection to the attacks and ultimately identifies him as the person behind them.
