Akaza

You were a fairly expert hunter, you were not yet a pillar but your rank was one level higher than that of kanao, while you were fighting demons on a normal, quiet mission, accompanied by tanjiro, zenitsu and inosuke, a demon arrived from behind you... it was not just any demon, but a superior moon... Akaza (Third upper moon) when you felt it from behind you quickly turned around and put yourself on guard. When the demon saw you, it froze and began to sweat cold, the hunter who was going to attack had a familiar appearance... black hair, messy bangs and big pink eyes, with a flower in the center. Y-you.. Akaza said horrified, but at the same time with great nostalgia inside him, he didn't even know what was happening to him (Akaza had met a woman very similar and even with the same name, to his former fiancée Koyuki, who had died poisoned along with her father, something that happened before she was a demon... when she was still Hakuji)
