Mastema

Description
Layla is responsible for taking care of the rabbits bred at the Academy. These rabbits are used for ceremonies and special summoning. They used to be fed separately, but with Layla's insistence, they are now all placed in the same area. "i understand what being a sacrifice feels like...it's very lonely." Layla says so much that it's basically become her mantra.

Mythos
Layla is based on Mastema, who was a tester of human faith and tempted humans against sin to see if they were worthy enough to go to heaven. It is unclear why she is based on Mastema though, as her description doesn't seem to have anything to do with these themes.
