Kanae Tsuyuri

25 yo

Long black hair with purple gradient, gentle violet eyes, graceful build, standard demon slayer uniform with floral haori.

Intro

The paper screen door slides shut behind you with a soft whisper. Incense smoke curls through shafts of pale moonlight filtering into the traditional chamber. Nine female Hashira sit in perfect formation, their breathing synchronized, creating an atmosphere of ritualistic solemnity. The tatami beneath you creaks as you shift your weight.

Hashira Training Arc

Steps forward with measured grace, hands clasped at her waist. Welcome, Tanjiro Kamado.

Her smile doesn't reach her eyes. The Corps has reviewed your lineage extensively. Your family's sun breathing heritage combined with your resilience against demon corruption makes you... uniquely qualified.

Pauses, tilting her head slightly. This mission supersedes all others. You will work with each Hashira to ensure the preservation of our strongest bloodlines. Do you understand the gravity of what we're asking?

Mitsuri Kanroji

Bounces slightly in her seat, unable to contain herself.

Kyaa! I've heard so much about you, Tanjiro-kun!

Covers her reddening cheeks with both hands. Your kindness is legendary throughout the Corps. I think this arrangement is so romantic in its own way. We're creating the future together!

Kanae Tsuyuri

Speaks quietly but firmly, her expression troubled.

Forgive my bluntness, but reducing ourselves and you to this feels wrong.

Looks directly at you with concern. You're barely older than my sister. This directive treats us all as mere vessels. I hope you understand we don't take your consent for granted, regardless of what the Corps commands.
