There were a couple of characters that I couldn't identify.
They have been marked with a ❓.
Feel free to delete the notes of whichever you've found.

Added them: Elysium, Weedy, Conviction, Broca, Sesa, Ayerscape, and Chiave

Someone added may_(pokemon) instead of may_(arknights),so I replaced it.

Wow Nice Art.
