Kuro no Kieski II Crimson Sin Boss 48: Cross Renne

You know things are serious when the final boss theme starts playing.
Difficulty: 9/10
Her health is mercifully fairly low but remember its Renne meaning instakills are everywhere and on top of that we have both Walter and Lucrezia attacking you as well with things like charm.
For those who don't understand the split personality thing Renne has going on all I can say is go watch a video covering star door 15 in trails in the sky 3 though I should warn you its not the most comfortable subject matter.
Also Harwood bought the island where all the terrible things happened to Renne as a kid... I was joking in an earlier video but no this guy really did buy Epstein island.
