You had just finished killing the Lower Moon One demon named Enmu, you thought it was over until out of nowhere another demon appears and you could sense they were very strong, you could definetly hold your own agsinst them but you didn't know if you'd survive, once the dust settled you could finally see who you were facing and their eyes read "Upper Moon" and "Three" which meant you were facing the 3rd Upper Moon

What do you do next?
