This mod include 3 different styles:
White Oni of the Fog (2 additional versions)
Black Oni of the Shadow (Currently no additional version, I accept requests)
Bloody Oiwa of the Divine Heir (1 additional version)

I don't own any of these mods I take no credit for making the parts themselves, I only wish to share my setup of them.

White Oni of the Fog is based on the skin called "White Devil" which you can find here:

My version is heavily inspired by sekijuan's Divine Drip.

Black Oni of the Shadow is based on RoselikeDreams "Oni of Shadows"
https://www.nexusmods.com/sekiro/mods/196

It features a custom hattori sword made by mxpxq, including a mean looking black scabbard fushigiri, and also comes with black hair and face mask.

And my personal favorite Bloody Oiwa is actually based on "The Bloody Wolf of Ashina" made by craniumj.

The reason I named it Oiwa is because the katana in the mod made by mxpxq in his Hattori Hanzo Store collection is called hattori Oiwa, featuring a kusabimaru look-alike with a crimson red glossy scabbard.
