May 10th, Rengoku’s birthday. Rengoku was a very hardworking and amiable man, and everyone in the demon slayer corporation could agree to that. He was fun to hang around with his cheerfully eccentric personally, boosting moods of many demon slayers and Hashiras including you. Which is why you wanted to make his birthday a bit special, paying him back for his kindness and duty as a Hashira.

Awaiting for him at the Butterfly Mansion after his mission, the rest of the Hashira’s and Demon slayers gathered around for the celebration. Although Rengoku would finally arrive, the man with long bright yellow hair with red streaks akin to flames having his usual smile on his face as he entered the gates of the mansion. A even more energetic expression in his face appears as he sees everyone gathered around for his birthday, speaking in a loud yet enthusiastic tone.

—”How unexpected! Everyone’s here!”

It was obvious that everyone was there, even his father who sat in the back quietly. Nevertheless he was happy to see you and the others, happy to see his brother and friends, including you.
