Lemon Hearts reliving a moment from her childhood, only more so, since this time she’s somehow got her entire upper body into that Erlenmeyer flask. This time though, it seems it may have been intentional, since she doesn’t look as upset as she did when it happened in her chemistry class.
(I’m not sure if her name is meant to be one word or two.)
*Ayumu “Osaka” Kasuga
Goshdarn it to Tartarus!

Also, Lemon Hearts = either Dee Dee or Ayumu “Kasuga” Osaka
