Touhou – Wriggle’s Insect Association
When it comes to youkai humans find unpleasant, Wriggle Nightbug is a good example. As to why she’s considered unpleasant, she always appears with a large number of bugs and can control them at will. Just imagine being simultaneously attacked by centipedes, caterpillars, moths, spiders, and cave crickets. It makes your hair stand on end.
This youkai appears similar as a human child. Fortunately, she doesn’t look completely like a bug. She only has antennae and wings but other than that, she doesn’t look any different from a human.
Wriggle is a bug youkai, but to be exact, she’s a firefly youkai. Fireflies, unlike most bugs, are popular with humans. Since this type of bug can avoid being exterminated by humans, it’s easy for them to mature into youkai. In addition, butterflies are similarly quite popular with humans, so it’s easy for them to become youkai.
