Akeru Nikki

Akeru Nikki is a Demon Slayer from the Taisho era. A bit classy at that, too. He always wears amazingly expensive clothes, varying from Haori's, to literally just shinobi pants. He's dedicated to his work, no matter what happens. He does have SOME sympathy for demons, though. His breathing style is Magma breathing, and he'll take down even some of the strongest demons without help. Best friends with Rengoku and Mitsuri, and even Tanjiro's gotten to him! (of course, he's a Hashira as well)
