Demon kind about brother (4)

I believe the answer is:

monk

'brother' is the definition.
(I've seen this before)

'demon kind about' is the wordplay.
'about' indicates a hidden word.
'MONK' can be found hidden inside 'demon kind'.

(Other definitions for monk that I've seen before include "Tonsured person" , "Religious brother" , "prayer?" , "One in a religious order" , "Member of a religious community" .)

I've seen this clue in The Mirror.
