ONA is a Spanish-Catalan Bilingual VOCALOID by Voctro Labs, she 'voiced' MAIKA. http://www.voctro-vocaloid.com/en/archives/871
Her first appearance was made at the 'Mercè Festival at Ciutadella Park' at a interactive Concert with Bruno and Clara.
MAIKA and ONA share the same voicebank yet MAIKA is the persona when used in Spanish and ONA is the persona when used in Catalan with her extra phonemes.
