アザミ

The Fourth-Ranked School Youkai. The elder sister of Sumire, she commands the growth of magical thistles. Azami uses her honeyed words to draw in prey.

The magical thistles are only visible to those who are being bullied. If they eat one of those thistles, they will become a bully themselves.

Her honeyed words are a terrifying hypocritical technique. Her ladylike manner of dressings draws in bullied children and makes them think she's some goddess who has come to save them. Apparently, there was once a time when she would take on a human guise and became an incredibly bad bully herself.
