Ohh my gosh they are such a sweetheart <333 I'd keep their name/gender, I think both really fit! ;w;

Personality: Dart can be a tad quiet at times, but can ramble on for hours if you give them the chance. They're quite excitable and bouncy at heart, especially when talking about their frogs. They adore their amphibians and are constantly trying to observe/find more; they'd spend all day exploring if given the chance. Dart does their best to be warm and supportive for their friends, but they tend to be a bit too nosy at times. Dart tries their best to be sincere and wholehearted; they adore their friends and the spontaneous adventures they find themselves in. 

I think Dart could fit in really well with some of my other characters and their story, specifically Tooru, Reyu, and Leon. I'm still looking for a couple more characters and Dart could def fit in with them <3 tysm for the opportunity!! ;w;
