Mitsuri: "if we introduce every hashira we have to include Rengoku as well"

Tanjiro: "that's right!"

Mitsuri: "Taisho Era secret again… Rengoku was a cool big brother! He trained and Taught me a lot of things! He also pampered me! Besides He use to eat a lot! You know Two of us ate a Big pot of sweet potato rice! It's wonderful memory"

Tanjiro: "wow! I wish I could have eat sweet potato rice with him!"

a weird distorted raspy choking like voice comes from behind the curtain inside of the deep pitch dark "I nostalgic I remember it too… finally the time has come to fight muzan kibutsuji has come… I'm counting on you guys…"

Mitsuri: "just now… was that rengoku…it's not a dream right?…"

Tanjiro: "hopefully not… that impossible Mr. Rengoku couldn't be here… he's gone…"

the tension on stage is a little too heavy as it all just takes a creepy turn there's no way rengoku could be here… he's dead… right?…
