a person who has a twisted mind and likes to do the opposite of what he/she is told or expected to do, or of what a majority of people do; a contrarian
Also 天邪鬼 in kanji. It originates from an imaginary character in Japanese folk tales.
I am fond of doing the opposite thing and so when someone tells me “Don’t do it”, I rather feel like doing it.
Because I love doing the opposite, I feel like studying after an exam period is over and feel like eating shaved ice in the dead of winter.
