Chika has her unique traits, apparently she has more phonetic data and 3 new phonemes in her vocals.

Basically, she seems to be a "Gumi mark 2", I felt this was alo the case with Kokone... Its like, they have Gumi in mind and know how to improve on her, but can't do that with Gumi herself so are recreating the things they'd like to do to Gumi in new vocals.
