I understand Gacha is home to a weird community of edgy kids but at the same time, they are good for getting a concrete design for characters, at least to some degree.

Here I assembled this slightly off scenario with four characters:
1. Selina, she is one the far left she classifies as a Kumquat.
2. From left to right after Selina we have Ludwig who is a normal Lemon.
3. Then we have Limella who is a normal Lime.
4. Finally to the furthest right we have Victor who is a Ponderosa Lemon.

I plan to fully fledge these characters out as time progresses maybe even starting a series going through the history of the Citrus people and culture while keeping to a main character and having a good narrative. Let me know what you think.
