Daisuke Ehara, professionally known as DAIDAI, is a Japanese music producer, composer, and multi-instrumentalist best known as the guitarist and producer for the genre-bending band Paledusk. Known for fusing metalcore, EDM, nu-metal, and hyperpop, DAIDAI has become one of the most innovative and recognizable figures in Japan's heavy music scene. His futuristic, chaotic sound design and genre-defying approach have earned him widespread acclaim in both underground and mainstream circles.

DAIDAI's contributions to ONE OK ROCK's DETOX album include three standout tracks. C.U.R.I.O.S.I.T.Y. (feat. Paledusk and CHICO CARLITO) is a genre-bending song that fuses heavy riffs, glitchy electronics, and rap features, reflecting his signature style. Puppets Can't Control You, is a high-energy, experimental anthem driven by mechanical rhythms and emotional intensity. +Matter, a dense, industrial-inspired track packed with tension and explosive dynamics.

His work helped push ONE OK ROCK into more experimental territory, expanding the band's palette with bold new production styles and electronic-metal fusion.
