Some people love her

She's interesting

>Kaiki on the list

And all was right in the world.

The exorcists are wasted characters. We need to get more books from their POV considering how good Hitagi End was because of Kaiki.

Also Kanbaru has so lucked out being born a Gaen. She has the good graces of at least three out of the five exorcists just from being born of Tooe.

>Some people lover her.
Because they watch the show or read the LN and formulate an opinion.
>Some people hate her.
Because they watch the show or read the LN and formulate an opinion.

On a side note, some people formulate an opinion without ever even having seen/read anything, so it's whatever.
