Yay, moon.
So. Magic charge options.
She's at maybe........ 650-700/1000 of the maximum she can comfortably hold? The numbers are made up anyway.
Expensive sweets and other nice foods- Call it about 10-20 per really nice meal? A good bonus but not really sustainable or efficient, when she can burn through hundreds in an intense fight.
Relaxing in the Woods Between- Maybe 1 or 2 per hour, good over a long rest but not for fast charging.
Hanging out in graveyards and otherworldly places tends to get her about five an hour.
Hanging out chilling with friends can be a pretty nice steady rate but she doesn't have her friends, here. And the 'go find a hookup' option just isn't one, actually, as far as she's concerned.
The moonlight dance really works much better; She can get 10 to 20 over an hour's dancing in her usual outfits, or 20 to 30 in a skimpy one- The phase of the moon can vary it that much as long as it's visible at all, but clouds disrupt it, and a totally new moon does too.
Except a nude moonlight dance is somehow much better, far more so than the additional skin would suggest. Thank you, Tamamo. Eyeroll. That's her mainstay for charging. It'll hit 75-100 an hour easy.
So. What are her options for acceptable privacy with a view of the sky... Empty dark parks and gardens? The woods outside the city? Both of those sound kind of... Dangerous. But she can set up alarm-ward illusions, and she's not exactly a soft target. Being attacked while naked is embarrassing as all hell but it's not like it's the end of the world.
She wends woods-ward via rooftop. Any convenient isolated/abandoned places along the way?
(Of course, she notes when the full moon is, out of habit. Her powers find themselves maximized, under it. Back home, at least.)
