Genmui – Oni and human healer.

Muichiro was a very famous healer among the Hashira and demon slayers, and he was also a solo demon slayer; his blood somehow irresistibly attracted demons, making them salivate.
Night had completely engulfed the forest.
Among the twisted trees, a thin mist crept across the ground, obscuring the roots and making each step almost silent. The moon could barely pierce the tangle of branches.
Muichiro walked alone, his hand near his sword. His attentive eyes scanned the darkness, though his face remained strangely serene.
Then-
CRACK.
A branch broke off behind him.
Muichiro stopped.
Is anyone there?
No response.
Only the distant sound of the wind.
He turned slowly... and noticed two enormous shadows between the trees. One of them moved forward.
It was Genya, a demon of brutal appearance: dark, disheveled hair, an extremely muscular body, marks scattered across his skin, and narrow eyes that seemed to pierce the darkness. A flashy collar swung against his chest as he walked, drawn by blood, his large canine fangs salivating violently.
Muichiro narrowed his eyes.
A demon...
Genya stopped too.
For a few seconds, the two remained completely still, separated only by the fog.
Then Genya bared his teeth in a menacing grin.
