This is Layer Cake (Iwai Shop Theme) from the Persona 5 Original Soundtrack
Replaces : Devil KAZUMI / TEKKEN 7
Place Layer_Cake_P.pak inside "TEKKEN 8\Polaris\Content\Paks\mods" folder
Loop is seamless, flows perfectly
Let me know if I should add anything else from the Persona series or leave requests in the comments and I will consider making them!
