Biography Daiki Kobayashi, a native of Toyonaka, Osaka Prefecture, was born on 23 September 1991. He was inspired to go into voice acting after learning that Oha Suta host Koichi Yamadera would appear in the show's anime segments, and he started enjoying reading textbooks aloud and became interested in late-night anime. He then spent about half a year at a training school in Osaka during high school.

In January 2016, it was announced that Kobayashi would star as the cross-dressing male idol Saki Mizushima in The Idolmaster SideM, a sub-franchise of The Idolmaster franchise; he subsequently received praise for his androgynous voice (which he was already known for at the time), with Kusuri Yūki from Net Lab praising it as "a perfect casting". Since then, he has performed as a singer on several Idolmaster music releases as part of the tie-in unit Cafe Parade, including the 2023 single "The Idolmaster SideM 49 Elements: 08: Cafe Parade" (which charted at #13 in the Oricon Singles Chart).

In 2016, Kobayashi was announced that he would star as Niko in Nanbaka.
