LON, definitely. Her voice stuck out to me since the very first time I heard it. Though, contrary to the apparent 'shota appeal' of her voice, I personally never thought she sounded like a shota. ༼ຈل͜ຈ༽
My favourite is che:櫻井. I love all the "versions" of her voice and the songs she sings. We used to tweet too once I decided to make her some chocolate for valentine and she was like "Yaaaay you're so cute" and I was like "omg" Anyways...just...fangirl things.
