Third Person pov
Oh wait. I forgot to take his sword. It would be trouble if I didn't, Shinobu thought.
It's pretty hot down here... I should probably take his haori off too.
Shinobu took his sword off his belt, then pushed his upper half up so she can take off his haori.
Jeez he's heavy, she thought.
She succeeded though.
Then she left and took his sword and haori with her, and locking the door behind her.
The door and walls of the room was made out of thick layers of wood, and not just a thin layer because she knew that Giyuu could break it.
After Giyuu woke up
Where am I...
Where is my haori?!
He looked at the note Shinobu wrote.
Oh, so I have to change into this yukata.
It was a plain white yukata.
Once he changed into is yukata, he neatly folded his demon slayer uniform and placed it on the foot of the bed.
He tried to open the door but realized it was locked. Ugh, of course it's locked, he thought
I wonder if they're going to let me out. Or are they going to leave me in here forever? Never going to let me go outside.
They'll have to let me out at one point. I'm not mentally ill after all.
Giyuu stayed in there, bored out of his mind. He had some crazy thoughts of killing everyone for locking him in here.
Maybe I am mentally ill after all...? Why am I thinking about killing people?
He didn't have his haori, which upset him a lot.
His haori comforted him, in every way possible.
But he doesn't have it right now. And he needs it.
Oh, I'm in the butterfly estate. This might be the basement. I've been in the estate before, a lot of times, and never seen this room.
He didn't have anything to do, so he just sat there. For hours. He was thirsty, and was also hungry. Why weren't they giving him a meal?
Why would they do this to me... I haven't done anything bad didn't I?
Giyuu felt betrayed. More than ever. He thought about what Muzan said.
Should I..should I do it? Should I become a demon?
He was so mad right now, he didn't really care if became a demon. He just wants to get revenge.
How will he get in contact with Muzan though? He can't get out.
Right when he laid down on the bed, Muzan suddenly appeared in front of him.
Oh god that scared me, Giyuu thought.
"Muzan?" he croaked out due to his lack of water.
"Yes." Muzan said as he nodded. "You look like a mess." he said as he brushed Giyuu's hair out of his face. (If one of you say this is a ship, I will murder you. This is literally so god damn cursed)
"So, are you going to become a demon?" Muzan asked.
"Yes..." Giyuu said quietly.
"Oh my, what's with the change of mind?" Muzan asked.
"The others betrayed me." Giyuu said with slight anger in his voice.
"I see. The feeling of betrayal." Muzan said.
"Nakime, teleport us." Muzan said.
In an instant, they were in the infinity castle.
"This will hurt." Muzan whispered to Giyuu.
With that, he plunged 4 of his fingers into Giyuu's forehead.
The pain... it's real.
Muzan has injected a lot of blood into Giyuu, and now Giyuu is rolling on the floor in pain. (Much like how Enmu was rolling on the floor and dying in s1 ep 26 xd)
"Welcome, Giyuu." Muzan said.
Giyuu then rose from the floor, looking as menacing as ever.
On his cheek, there were marks that looked like water (looks like his demon slayer mark). (There were also marks like that over his body, just not seeing much of them because of his clothing).
He still had his blue eyes, but the pupils were cat-like just like Muzan's.
He had canine-like teeth, just like all of the demons.
