Welcome to the alternate universe of Underhand!
This universe was created on the theme of AU Undertale, but it has a close connection with the theme of Handplates, I would say something similar to a parallel version if Dr. Gaster "existed" a third subject, the so-called 3-Y, or otherwise 3-A. In other words, when Gaster did not expect the appearance of his "third creation" at all, under no circumstances, and the damaged capsule decided for him, which created one of the previous two subjects (1-S and 2-P).
Which character do I pay the most attention to? Absolutely right, 3-A, since she is a heroine is full of riddles and mysteries, despite the fact that we know the three characters themselves quite well as Gaster, 1-S and 2-P. We know their relationship to each other, their opinions on life and the story monsters and humans, their abilities and many other factors, but not the 3-A itself, which is part of this Underhand franchise.
I'm sorry that the 3-A physique is closer to the male type, but I'm still learning how to draw similar characters, so don't throw "BONES" at me. Anyway, this is only the first time I'm drawing my characters on the Undertale theme, heh. -ˊ▿ˋ-"
