Remembering this game

So its been I suppose more than a decade since I played this (it was a wild ride and called it an MH-clone but it was fun) and I still have my psp save file, now I can't seem to remember this item I needed but I know for a fact it required parts of a Kongou and I know for a fact that I needed to break his back for it (from what I remember I suppose) and I did give up after reducing its population. Not to mention I was stuck on a very high level mission where there are two Hannibal and I think a stronger version of an Aragami.

It's been long time and I am not even sure its even worth it to continue getting that item
