The 'trypophobia' reference is a nice touch because it adds a layer of psychological horror to the bugs. It's not just disgusting—it's triggering a specific fear in the reader too. That's clever writing that makes the threat feel more personal.
Chou Chou is the cutest protagonist ever. Her inner voice is so sassy and smart for a newborn, and the way she tries to “wiggle her little fish tail” but can’t is both funny and endearing. I love that she still thinks like a koi but has to deal with human baby problems.
The whole concept of "people fear ghosts by a third, ghosts fear people by seven-tenths" is such a cool piece of folklore to incorporate. I love that the solution to the female corpse's eyes not closing isn't some elaborate ritual, it's just slapping her and cussing her out. The protagonist calling her a stinky woman and threatening to have King Yama pull out her tongue is hilarious and badass. It shows a really practical, no-nonsense approach to the supernatural that I appreciate. Too many horror stories have characters who are afraid of everything. This guy just treats a vengeful corpse like a difficult customer, which fits his personality perfectly. It also adds a layer of reliability to his knowledge. He learned from his grandpa, and his grandpa's methods work. Makes me trust that when he does something weird, there's a reason for it.
