Thanks for the chapter!
Medusa looks like a Lamia. Idiots shouldn't have convinced themselves nothing was wrong and hit the alarm once she started laughing. That and have alarm button within reach at all times so can hit it as once things go south it'll happen fast. Although that excuse about him not asking is really lame considering it's not a subject he'd think he had a reason to bring up. How'd he know he had a fiancé if she never told him? The mother is both surprisingly delicate and strong. Able to stop her daughter's arms yet will collapse half dead just from being firmly spoken to. Poor bear, why'd his ear catch fire? You'd think Ayaka would be happy to hear about being his fiancé unless fire breaks out when she's feeling really emotional and not just angry? Interesting how during all of sister's antics the bear is always with her.
MC can really be dense. Three statues of maids and yet he calmly wonders if the woman in the straight jacket surrounded by snakes is another maid? She's obviously a Tower Witch. Also, the doors burst open and break and yet the glass elevator doesn't even get a crack?
Guess the white stuff was a reference to Evermillion. Is it me, or does she really resemble Ayaka?
