You may use this song freely for any purpose.

For this mashup I used the song Vi et animo that is part of the god eater resurrection soundtrack, specifically the Arius Nova fight, combined with the themes of valstrax, from monster hunter GU, and the "leitmotiv" of "To one with live" which is the main theme of MH3. a little bit also of the theme of raging brachydios, which first appeared in Monster Hunter 4 Ultimate, is used.

I did not sample or rip none of the original songs but vi et animo, instead I recomposed the parts of them that seemed most consistent to me by ear, and used vi et animo in the background to make the song sound fuller.
