This is one of my characters for representation purposes, so while this has a design, and perhaps some points of interest, I have no plans of a story with this one. I say I have no plans, but there might be lore at some point. Might.
As with Megureisu, "Kei" is from megumi (恵), which means blessing or grace, but with a different reading. The maashii part is from "mercy" spelled out in katakana (マーシー). At least, that's what I think it is... I tried to check dictionaries, but I only have proof for names that have "mercy" in them. Either way, that sticks for now.
I did not plan to actually have a second representative character, but here we are. For the most part, I was just thinking along the lines of "What would be a contrast with Megureisu (in terms of design)?"
Uh... Cat body but with lizard outer features? Something something whale shark tail? Hair that's raised up instead of going downward?
If there is anything unique that it contributed, the concept of the two characters having robotic elements (the eyes, mostly) actually started when this one came along.
As with Megureisu, I still have to draw. Actually, I have to draw more since this doesn't have much yet.
Random and cursed thought: Full name being Kei Maashii A. Wa
