SEIUN brings character concepts to life with art, music, and technology.

Viki Hopper’s UTAU voicebanks were released in May 2016. Since then, the character has been featured in original works by producers such as Avalia, Temjin, EmpathP, and Seagull.

Viki performed live as an animated projection with VOCAMERICA, the western Vocaloid Concert.
