And where is Emilia?
I mean, she is Echidna.
Character dolls are witches of sins from re:zero and Satella.

Ekidna-sama !!! *ahem* The chibi are Minerva (blonde), Typhon (green hair), Daphne (sarcophagus girl), and the other two are probably Carmilla (pink hair) and Sekhmet (purple haired girl who's lying down). The one with the veil and the hands is Satella ^^
