Added Miia to Characters, as that is her voice off-screen warning Rachnera not to stay too long in the hot bath.

Huh, I remember Rachnera mentioning in the manga that her lungs were in her abdomen like where a normal spider's would be, so she wouldn't be able to breathe if she got in the bath. Makes me wonder if her human torso even has any organs besides an esophagus.

Most spiders can survive submerged in water for several hours to over a day by trapping air in their body hairs, with some species, such as wolf spiders, surviving up to 40 hours by entering a coma-like state. They avoid drowning using hydrophobic hairs that create an air bubble for breathing.
