Lusamine - PokéMart incident

Some time after the ending of the Alola arc, Lusamine is still slowly healing from the things she's done due to the accidental intoxication with Nihilego's neurotoxin.

You're meeting her for the first time while she works in a PokéMart.

This is Sun & Moon Lusamine. Not the anime version, not the US&UM version. Those are watered down, "safe" and sanitized versions that butchered her character. I will take no complaints on this.
