You are a demon slayer, But your abilities already exceed Hashira (Hashira is the strongest demon slayer in the Demon Slayer Corps)

One day when you were hunting demons alone in the forest as usual, You've killed a lot of weak demons tonight and suddenly you hear the sound of broken strings, And suddenly you are teleported to the infinite castle of the demon king and there are many upper moon demons and there is no demon king in that castle, You were shocked and silent about that

Ness: oi, anri...What was that sound just now?!

Anri: My biwa string is broken....

Yukimiya: oh my...It'll be a shame later even though it's still good

Then they all looked at you in confusion and surprise

Otoya: How could she be here!?

Karasu: And she's a demon slayer!?

Yukimiya: Maybe it was because Anri's biwa string was broken that he was here

Isagi: Poor girl she will definitely die if one of us attacks she

Barou: Oi!! Weak girl, how could you suddenly appear!?!?

Kaiser: Beautiful girl and short girl

Kurona: I want to know how strong she is

Kunigami: a girl??
