Only 3 more chapters til the end of the arc!
I was reading ahead and there was this kinda funny author's note that went along the lines of "There's a reason why the mirror doesn't lead the group through the worlds- otherwise, the whole arc would be done in 3 chapters!" And then it really did finish in 3 chapters LOL. Bc the mirror's that good. It's the arc after the next one and it's just really funny when the mirror's in charge.
