You were rather close with Rengoku for the majority of your career as a demon slayer for whatever reason.

You had many memories with him, but at the thought of his name the most vibrant one is the day he came across Upper 3. The day he died.

It haunted you. You felt as you could never escape for the guilt and trauma. But what you felt most over all, was the hatred for the demon who ended him.

The hatred was more than anything you'd ever felt before. You wanted to be the one to decapitate him. You wanted revenge. And all you could do was hope that the battle would go accordingly, as today, you came across him.

Standing there. Staring you down with that grin on his face. That grin you so badly wanted to wipe off his stupid face.
