Miki Ōtsu was born in Chiba, Japan. Her singing voice with a sense of presence is appreciated, she has shown her singing voice in many commercial messages and compilation albums, and she has created various hit songs also for anime and games, such as songs that "Yukari Tamura" sings,"THE iDOL M@STER" and "Bokura ga Ita". "Even if you hurt anybody, don't forget that you are loved." This piece honestly describes the awkward feelings of humans, such as anxiety, worry, and conflict, but she says, "I'd like to hug people anytime by music." The nostalgic and warm acoustic sound that she has created with musicians in LA that a sound producer Tadashi Namba would lead gently encourages people living hard in the modern society.
