Artist's commentary
Efroid: Model Dark-san from Katou Takuji's (@isiyumi ) works.
Dark-san is a proud warrior, so being seen while she is undergoing maintenance takes off some of her aggressive edge. You're all good kids, so I'm keeping this All Ages for you.
You go girl, Dark. You're unflappable.
But she might be weak against being getting spoiled.
Oh and I don't why, but I even drew a few variations of this.
