Hino Enma is an ancient Yokai that lures men into her den to keep them away from their wives and obviously kills them by drinking their blood.
That was the first Nioh boss that caused me a lot of problems but in the end Hino Enma wasn't so hard to beat. First of all use your back dash to keep yourself away from her hits with umbrella or leg combo. Hino Enma uses banshee scream (demonic purple balls) that may paralyze you if them hit you. She also using flying charge atack that can one-shot you so be careful. Between her atacks there is a little amount of time when you can hit her by 2 or 3 hits depending of the weapon that you chose. I'am playing with fast and strong weapon like Tonfa's and Dual Blades. But i mostly using my tonfas because of speed and nice dmg in middle stance.
Second phase of that boss is about Hino Enma become flying and really annoying spitter. Use your dashes and evade all of those nukes that she will crumple on you from air. U can also use your secondary weapon like bows and cannons to smash her from air to the ground. In that moment rush to her and do your combos.
On 35% of her hp you can release your're Guardian Spirit and finish her with a big feeling of pride :)
