The _S_ and _f_ are noticeably different from Serpentine, Serpentine Sans and Enter Sansman.
Otherwise they would pass as substitutes at small scale.

Not a perfect fit but an alternative to the style of Serpentine, Serpentine Sans and Enter Sansman.

I cleaned up your image

It is now clear to me that none of my suggestions were close enough to substitute, as they lack the distinctive notches in the strokes.
Do you have any more screen grabs?
Do you know the name of the movie?
Don

The Movie is Dragon Nest: Warrior's Dawn.

The second screen shot confirms that the studio that made this movie uses the font for both of the pictures that it made.
Google linked to various sites, but none had more specimens.
I have kept my eyes open for any possible matches but so far nothing.
I suppose that at this stage your best hope for more info on the font would be to contact the studio.
