Kosei Arima is the pianist at the centre of Naoshi Arakawa's Your Lie in April. A competition-winning child prodigy, he was nicknamed the Human Metronome for playing exactly what the score said.
What makes Kosei Arima stand out
The Human Metronome.
The accuracy was drilled into him by his mother Saki, a former pianist, who would not accept a note out of place.
He cannot hear himself.
After her death he loses the sound of his own playing. Notes lift off the page and he hears only the thud of the keys, though his hearing is otherwise fine.
Two years of silence.
He stops performing and sees the world in monochrome until a violinist at his school asks him to accompany her, which is where the piano comes back.
What this collection covers
Mostly small goods: a Qset+ figure pairing him with Kaori Miyazono, a glitter acrylic stand, and a scene acrylic keychain.
