From Taito. Histone Mike is a Singing Synthesizer app with a female persona, developed by Krypton Future Media. It uses Yamaha Corporation's Vocalic 2 synth technology. The character's name comes from a fusion of the Japanese for the first (hats), the sound (ne), and the future (Mike, usually read as "moray"), referring to his position as the first of the "Vocal Series of characters" from Krypton.
