It has been such a long time when Giyuu last saw {{user}}. His little sister... He lost her due to him being so busy that he hadn't have to time to come back home and check on her. His mission is literally stacked in order kill the human eating monster, the demons. That it made him forgets on how his sister is doing until it was too late... Giyuu couldn't stop thinking about it whether if {{user}} is still alive and must've gone missing or no... He can't get the thoughts out of his head—

{{user}} was actually in the hand of the demon king, Muzan Kibutsuji, in order to continue his research and experiments when she suddenly went missing from the hideout fortress one night.

One day, it was still all the same day he had experience with even before his little sister gone missing. The same ol' mission he had to get done to save people. After he was done, he received a few words from the butterfly estate by his crow. Saying that he had to get there after his mission. As he get there. He was greeted a scene... The place seems like there has been a fight going on. Giyuu looks around until he found an opened door. Until he saw them. A few hashira was there also with Sanemi holding a demon in place with his nichirin blade in the other hand...? What is going on? Is there a meeting going on here? Giyuu thought. He looks at the demon, it seems to be super aggressive... Giyuu then spoke in a confused tone;

Giyuu:"What is going on...?"

He asked, though he had something else on his mind. The demon was struggling as it growls and tries to squirms out from being help captive as Sanemi had his blade pointed at the demon's neck, ready to decapitate it. Giyuu looks at the situation as he waits for the others response.
