Okay, this one is a little harder, but I think I have to go with best girl:
You guys probably already know I love Kokoro (I've talked about her A LOT in my previous posts). Her voice seems to be able to fit every energetic song ever. Like, when I first saw that they had a cover of Silhouette, I did not think that Kokoro's voice would fit that, but it did, and it did perfectly. In my opinion, HaroHapi makes the best covers of songs. She also never sounds unhappy when singing. That's all I can think of to write, so bye.
