GROWING STARS Biography
-From composer to idol!-
"Can you hear my sound?"
THE iDOLM@STER POPLINKS Profile Quote
"... Ah, pardon me. A sound came down. A new sound is born... Oh, it's you."
Kei is a calm and mysterious composer and musician. He considers music to be all that he has, and focuses solely on it; he believes all sounds to be beautiful and finds enjoyment in little things. Kei hopes with his idol career that he can continue to explore music and move people with his songs.
He is quite carefree, having chosen to become an idol solely based on Rei’s music, and often appears relaxed. Kei sometimes enters ‘his own world’ when dazed by music, causing him to continue singing or playing even after the song has ended. Kei falls asleep easily and is forgetful, not even remembering his own age.
Because of his airy attitude, Rei often has to keep Kei in check. He can appear irresponsible due to his reliance on Rei, but he cares deeply for him. Kei formerly thought of himself to be useless without his musical talent and believed that Rei and Producer would be fine with leaving him at any time.
Kei’s mother is German and his father is Japanese. When he was young, they divorced and his mother took him to live in Germany, where he grew up in Berlin. There, he had a quiet life, living in an apartment where there was a concert hall nearby. Listening to the music played ‘brought color’ into Kei’s life, and inspired him to become a composer. He had a friend in Berlin who suddenly disappeared, affecting his current state.
Kei provided the debut song for the legendary songstress idol. Writing music for the songstress was his everything; after she suddenly retired, he had no joy in life until he met Rei and Producer.
In Japan, Producer scouted Kei while he was singing in the rain. At the recording studio, he found himself amazed by Rei’s violin playing and regained his passion and happiness.
