I love Sana so much. She's so cute. The way she makes cute noises like "oosh" while she's playing games. She's energetic but her voice is deep enough to be soothing so you don't get tired of listening to it. The cute nicknames she comes up with for everyone. She's probably an adult but she behaves in a youthful way that is very endearing. And she's actually legitimately skilled at games like Ina so you don't have to watch her bungling through something easy for an hour. Apparently being a good artist also gives you good gaming skill. She's really smart and well-read. And her taste is excellent.
