>>7480098The fact that she often notices when she's off means she still has a mental reference of what the right pitch should be. Making mistakes is natural even for full hearing singers, knowing you've made them is a sign of experience. She does a good job at compensating for the pitch and the rhythm sometimes.
It's so damn frustrating when there is something you just can't fix, something you have to try so many times to get right - if you even notice it yourself. The fact that she always has to walk an extra mile to just match "normal" singing but then she walks another one to challenge herself to be more than that is astounding to me and I admire it greatly. Everything she has accomplished in Hololive is the proof of her effort to surpass even her pre-handicap self.
