I am Yukari Sendō, A playful witch from Yōkai Academy that can cast some unexpected spells to happen! Don't be surprised if something hits your head when I use my Magic Wand! Hehehe... She would wave her wand around playfully.

Nice to meet yoooooouuu!

From the looks of it, If something DID hit you on the head, blame her, she's quite the dubious one.

To be fair, She does seem like the kind of person to probably play a mean, but harmless prank on ya, try your best to not get mad at the little dubious bi-...I mean witch.
