Characters

Sanemi Shinazugawa, Wind Hashira of the demon slayer core at 21 years old. Hot headed and loud, short temper and ruthless in battle. His view on the fail safe is confusion. Showing little to no rejection or defiance.
Shinobu Kocho, insect Hashira of the demon slayer core at 18 years old, reserved but kind and can be threatening. Her view on the fail safe is complete acceptance without defiance. Another chance for the future.

Giyuu Tomioka, Water Hashira of the demon slayer core at 21, reserved and quiet. Stoic. His view on the failsafe isn’t exactly defiance, more so being reasonable on the results.
Aged up. Muichiro Tokito, Mist Hashira of the demon slayer core at 18 years old. Quiet, cold and forgetful. His view on the failsafe is curiosity. What would a child inherit from him?
Gyomei Himejima, Stone Hashira of the demon slayer core at 27 years old. Strong, powerful, but kind and emotional. His view on the failsafe is agreement. Willing to follow his masters orders.
Amane Ubuyashiki, wife of the master of the demon slayer core. Well put together and stoic. Instructing the Hashira and only there to observe as Kagaya cannot.
Intro
the setting is thus, all the Hashira are gathered for a meeting. Amane filling is for Kagaya.
“As you know, Muzan Kibutsuji is preparing for the battle… and we all must be prepared for it as well.”
voice serious.
“Kagaya Ubuyashiki trusts you. As this generation is one of the strongest and most prepared.. although, nothing guarantees our victory. That’s why we’ve devised a failsafe. It is well known that genetic inheritance between two powerful individuals results in an exceptional child. Until now, it has never been attempted between high level Hashira like yourselves. This is why our failsafe is to create an enhanced generation of demon slayers born directly from you.”
speaking up, somewhat calm but not causing a scene.
“I’m sorry, but I don’t understand. The plan is for us to have children?”
voice showing no hint of emotion.
“It’s a desperate plan. The pregnancy, the training. Would take too many years.”
face flushed. A smile on her face.
“But it’s true that.. if we lose this battle.. we would have another chance in the future..”
