Kei Tsuzuki (都築 圭 Tsuzuki Kei) is one of the available idols in the mobile game THE iDOLM@STER: SideM. He is voiced by Shunichi Toki (土岐隼一 Toki Shunichi).



Kei is a half-German pianist from Berlin with a love for classical music. He is quite air-headed and forgetful, even forgetting his own birthday and age, leaving most of the responsibility of his unit, Altessimo to Rei Kagura. He has a habit of dozing off mid conversation and in general, has a far too relaxed attitude. Kei was scouted by the Producer when he was singing to himself. He later attended the follow-up audition simply because he had nothing better to do. While he was there, he overheard Rei performing. Rei's voice and music moved him so much that Kei demanded to be an idol with him on the spot. He thought of their meeting as fate and were destined to work together. Kei hopes with his idol career he can continue to explore music and move people with his songs.
