"See you around, hottie."

She sees them off with a wave.

And Ruby gets to work. 

The first major order of business is establishing herself as a supervillain - she frontloads bounties, notes with some ugh that somebody else already took out the only interesting (and high value, long lasting) bounties in the United States - the Slaughterhouse Nine were taken out by a new hero (who promptly vanished from public view) a bit before she dropped over, and while Bonesaw was initially marked missing, the government later quietly marked her case as 'handled.' Ruby isn't really interested enough to follow up on that...

Still, she makes serious bank with international bounties, enough for a large plot of land a convenient distance from the city (a volcano lair would be a bit tempting fate, but she can do some fun volcanic artistic theming, she thinks) and to (quietly) buy up the materials she can't make or gather herself. (She's decided to do most of the construction herself.) She also figures out how to get a proper fake identity off the black market, gets an ID and a copy of her school records as Ruby Sachs for her civilian identity, signs up for some classes in her free time...

And trains Ellie, of course, who by the way needs to pick her magical girl name properly before the big formal debut. 

Eeeeeh. Can't she just go with "Shadow Carnelian Necromancer", that seems fine to her...

Siggghhhh. Of course, but it's tradition to add on a name at the end! Ellie'll want something cool, not one of the lame frilly names a lot of magical girls use, but there's plenty of options out there... Like Nyx!

Goddess of night? Not too bad. Definitely leaning into the edginess. Though maybe something like Ereshkigal would be more thematically appropriate. Underworld and all.

Hum... "Shadow Carnelian Necromancer Ereshkigal is a bit long... Though the two/ four/ three/ four syllable pattern is pretty good, nice and poetic. And it's definitely more monstery than most magical girl names!"

"Suits us, yeah?"

"Very much so." Headbutt?

Celebratory headbutt.

Heee!!!

"We should do our debut soon, let the world know how terribly beautiful we are."

"Get started on properly flirting with your nemesis?"

"As a villain, at least."

"Think she'll put the dots together?"

"Dunno. I'm pretty sneaky..."

"Maybe she'll match the butts if you use that costume you've been workshopping."

Sulk! "I'll be usually tiger shaped..." she grumbles, before perking up. "Though, that'd be funny enough to be acceptable."

"Imagine the look on her face."

Chuckle. "Though hopefully she doesn't out me in the middle of the street..."

"That'd be bad cape manners. Probably she'd just send you a strongly-worded text later."

"As long as she's still open to being my nemesis..."

"Aw, how could anyone give you up?"

"No one reasonable!"

Laugh. "Yeah, exactly."
