>>1258232The biggest thing is that she has shown no inclinations of not being fairly limited in range. The one time she's attempted to go high, as far as I can remember was
https://youtu.be/I8M4BvdxOVY?t=1314, and she clearly couldn't. Maybe she'd have done better if this wasn't 50 minutes into a set, but that's hardly an excuse when you have AZKi doing multi-hour performances of her songs without a significant dropoff.
Her voice is very pleasant, and while she has said as much about not knowing singing techniques such as vibrato, she's normally able to hit the notes well enough that she doesn't need to use that tool to 'cheat' by wavering around the perfect pitch, but that's because she mainly sings songs that have a very limited range. She has amazing lung capacity and sense of rhythm from doing all her rapping reps, but we also haven't heard her do anything like sliding from one note to the next, which is part practice but part how smoothly your voice will respond to it. Instead, she has a clear break between each note even if it's within the same word, if you listen back to earlier in the Lion performance. Kiara's chicken voice is a significant limiter, but she's still able to slide from note to note. That might be more of something that Mori is just not practiced at all since she's used to spitting verses where pronunciation is more important, but we'll see. I'd love to hear her try a song with a wider range where she starts lower but until she does, I can only speculate.
Keep in mind that low is relative as well. She's an acceptable to good singer, and far better then the average Japanese idol and a decent chunk of the Holos. However, she's just that much better of a rapper that it would be a waste for her to dedicate all of her music production to something she's merely good at instead of the stellar raps.
