Umezz: Tomes of Horror - Serpent

In Serpent:

A sudden tragedy strikes the Numata sisters, as the older sister collapses with a mysterious illness that leaves her unable to move her limbs. Her younger sister cares for her devotedly, but begins to grow suspicious of her sibling’s strange behavior… Could she actually be a murderous snake in disguise?

This primal fear of serpents creeps in with unsettling unease in The Scaly Face, along with two other snake-themed horror stories - Snake Girl and the Silver-Haired Witch, and When the Mouth Rips to the Ears.
