I am attempting to read RAW manga for this first time, and I am encontering a
varigated use of カタカナ and ひらがな in sentences that leaves me puzzled.

The whole sentence is: 「勉強しなくていいさし、悪者退治なんて **スカッと** しそうだし」。

From a quick Google search I believe the meaning of the bolded word is
"refreshingly; w/ a sense of relief" (please correct me if I'm wrong). I am
aware that it is commonplace for words to be inputted in カタカナ for emphasis,
however I am unsure if the と here is intended to be included in the word (and
is intentional/misprint), or is actually some grammar point I am unaware of.

Any answers would be appreciated!
