This is Limoncello (or Limon, or just Lim), the Lightning Witch! While her electric powers could certainly do a lot of damage, she’s actually a good-natured witch who dedicates her magic to mundane ends. For instance, she can power devices and heat food through convection. Most impressively, she can bring inanimate objects to life with a jolt of her magic lightning and then have them help around the house. The main character in this story is actually a stuffed toy that was animated in this manner. But I hope to get to her later.
When I drew those chibis a few weeks back, I decided I wanted to use that style for a new story that I haven't yet named. It’s a very basic and all-ages kind of story though, and maybe the kind of thing that would suit a game better.
