Yamada

Tbh she also acts like a Tsundere

She is really hateable in alot of ways but she also has a softer, sweet side that your able to see which is what makes you root for her to grow with each espiode and slowly start to show her true self 

She never knows what she really wants, and sometimes manipulates people just to get what she believes she wants at the time, just for her opinion to change 5 minutes later.

she is a funny character, I think that for her personality she would be a Kamidere, since she likes very much to be the best in everything.

Yamada you need get a FUCKING life with someone, that's you are worst female in the show.
