Need help in determining the number of semi-tones was pitched up in a cover

In this cover, Ashe pitched up the instrumental so he could sing it on a lower key.
I'm planning on covering the same song with a male UTAU and would want the cover to have the same key so I can use UTAlis using Ashe's vocals.
I believe he used the instrumental of the original song (not the remake but please tell me if it is) but I won't be able to extract his vocals from the instrumental if I don't have the same instrumental use and on the same key. After a number of trial and error on Audacity of pitching up the instrumental (both the original and remake), I still have a hard time determining the number of semi-tones was pitched up

i believe he pitched it up 2 semitones, from F# to G#

Thank you SOOO much!

Unfortunately, the extracted audio ended up too distorted for UTAlis, but at least I now have a peace of mind on what key the UST should be in ^^
