The 3 Angels of Death

Owarinohajimari

Rimuro's training to obtain the Demon Slayer Mark could only be described with one word HELL

The method was simple but cruel Rimuro deduced that the Demon Slayer Mark appears once the wielder is in a total state of desperation for survival with all odds against them so Rimuro's method of training was to put them through every conceivable form of suffering in battle to lead them to desperation of survival within the first minute over 3 quarters of remaining Demon Slayers quit Rimuro held nothing back against them it was also a rule that anyone who passed out would be expelled from his training never to return this eliminated a great multitude of the remaining Demon Slayers to where few remained though cruel as they were Rimuro's methods were effective before the sun set all the Hashira had come close to acquiring their marks

Rimuro: All your temperatures are over 39 Degrees Celsius I'd say you're all ready to gain your marks when the Final Battle arrives

Sanemi: You know . . . the way you flip a switch . . . really pisses me off

Rimuro: Nezuko go ahead and heal them now

Nezuko: FINALLY

Nezuko hastily healed all the Hashira and Demon Slayers present

Rimuro: Nice job you all survived you can rest for the night we'll pick this up again at sunrise

The mere words of relief that it was all over were relaxing enough that all the other Demon Slayers passed out

Tanjiro: Brother are you sure we didn't go too hard on them

Rimuro: It's a necessary evil now there's one more thing left to do

The Hashira all gathered in the center of Rimuro's Mansion

Rimuro: Now as you all know the Demon Slayer Mark comes with a toll that all those who have it die at the age of 25 all except for one that is

Muichiro: Our ancestor Yoriichi

Rimuro: Yes but Tanjiro here had the same condition as him he was born with the Mark

Obanai: We know this much already what does that have to do with anything

Ciel: Iguro don't interrupt him

Obanai rolled his eyes

Rimuro: The point is that with the help of a doctor named Tamayo, we've found a cure for the curse of the Mark

Every Hashira aside from Ciel and Tanjiro were shocked to hear this

Sanemi: THIS BETTER NOT BE ONE OF YOUR JOKES

Rimuro: I would not joke about something like this I'm serious

Shinobu: What doctor could achieve this feat

Rimuro: . . . A demon doctor

The Hashira had an even bigger look of shock on their faces

Sanemi: TSUGIKUNI ARE YOU SERIOUS

Obanai: A demon surely you jest

Rimuro: I'm serious this is no joke I vouch for her and so does the Master I have a letter of approval from him

Ciel: (I'm never gonna get used to him calling anyone that)

Rimuro pulled out a note from Ubuyashiki that was a written voucher for Tamayo

Rimuro: He knew that she arrived at our Mansion to complete the Mark so he sent this note in advance you all can trust her and if and to solidify any of your doubts just remember this is ME we're talking about and I vouch for her with my life and everything I hold dear
