Giyuu's burnt haori

It was the most ordinary day... probably. Giyu's haori, as always, after another battle with a demon, had been sent to the Butterfly Mansion for cleaning. Meanwhile, a conversation between Sanemi and Obanai.
Sanemi: Tomioka has been pissing me off so much lately.
Obanai: Agreed.
Sanemi: Oh~ Hey, why don't we play a prank on him?
Obanai: A prank? How?
Sanemi: Let's burn his haori!?
Obanai: Hmm... Not a bad idea~ I don't like that stupid haori of his... anyway~
Sanemi: Exactly! It's high time he updated it~ And so, they came up with a small plan and took Giyu's haori from the Butterfly Mansion, under the pretext of delivering it to Giyu...
The next day, Giyu came to the Butterfly Mansion.
Giyu: Shinobu, hello. I'm here for my haori.
Shinobu: Huh? Didn't you ask Shinazugawa to pick up your haori?
Giyu: No...
Shinobu: Strange... he just took your haori yesterday and said he'd give it to you :)
Giyu: I see... thanks for the answer.
He left. In a small square.
Giyu, noticing Sanemi and Obanai, walked toward them... He became slightly alert... because of the fire next to them.
Giyu: Sanemi, Kocho said that my haori is with you. Could you give it back?
Sanemi: Hmm~ Sorry, but that's... impossible~
Giyu: Eh? Why?
Obanai: Because it's right there in that fire~
Sanemi: Oh, don't worry, your haori is so weird anyway~ We'll buy you a new one~
Obanai: Yeah. It's about time to update that stupid haori~ Giyu suddenly froze... His face darkened, his vision blurred... a flood of thoughts rushed through his head: "How!? / Why!? / Am I really so worthless that I couldn't even preserve the memory of Sabito and Tsutako...?" Sanemi and Obanai, noticing Giyu's violent reaction, stopped laughing... And Giyu... Giyu suddenly lunged into the fire. Sanemi and Obanai were terrified and immediately rushed to Giyu... Sanemi grabbed Giyu's arms, pulling them behind his back to stop him, while Obanai stood in front of Giyu, trying to shield him from the fire and placing his hands on his shoulders to calm him down.
Sanemi: What the hell are you doing!?
Giyu: Let go! I have to get it out of there!
Obanai: Someone bring water!
Quick footsteps are heard nearby; Uzui and Rengoku are bringing water. The fire was extinguished. Almost nothing remained of Giyu's haori, only small scraps of fabric...
Obanai: Hey... what's wrong with you?
Sanemi: Have you completely lost your mind!?
