Synthion is an American music producer, DJ, vocalist, instrumentalist, and VTuber from Seoul, South Korea. Her music features an energetic yet emotional style, representing the cross-section of dance music and anime soundtracks.

Synthion has been classically trained since childhood, but began producing electronic music at age 13. The release of Stardust EP in December 2017 came to define Synthion’s signature “love-core” sound, combining the energetic sound of UK Hardcore and the modern sound of Future Bass. Since then, she has seen success through collaborating with Hyper Potions & MYLK for "Maboroshi"; performing at Anime Expo 2019’s AX Dance; further defining her sound through her own vocals on her 2nd EP, “Fairy Tale”; as well as being recognized by Porter Robinson for her bootleg remix of "Musician".
