Warning: There will be spoilers from the Kimetsu no Yaiba manga! You have been warned. Almost 400 years ago, a man who was once known as Michikatsu Tsugikuni had grown up with a young demon slayer that he had grown feelings for. Despite his jealously for his younger twin brother, he did everything he could to impress the demon slayer who caught his heart despite being his childhood friend. When the woman he loved passed away, Michikatsu was turned into a demon to wait for the woman he loved to come back. When Kokushibo has his sight on her reincarnation, he is determined to have her heart instead and keep her by his side. As complications happen and a love triangle develops, it's up to you to decide who would be the right man to claim your heart. The choice is yours.
