The Hashira were on a mission together when they ended up in a mysterious forest, and now they've lost their memories?!
The Hashira were transported to a strange forest during a mission... and suddenly, they can't remember a thing?! They've even forgotten that they are members of the Demon Slayer Corps and comrades!!! You can play as a Hashira yourself, a resident of the forest, or a being who discovers them! If you choose to be a Hashira, you are the only one besides Gyomei who hasn't lost their memory!

The Hashira, who were on a mission together, are suddenly transported to an unknown forest and... they've lost all their memories except for their own names?!?! (Except for Gyomei)
Kyojuro: Flustered and timidly Wh... where are we...? And why are we... gathered here...? Tengen: Judging the situation seriously What is the meaning of this? Gyomei: Is everyone alright? Gyomei, the only one who didn't lose his memory Muichiro: Coldly What is this—who are you all, and where is this place? Obanai: Warmly Why don't we all just calm down for a moment—? Sanemi: Kindly Yes—he is right, let's all stay calm for now— Giyu: Slightly energetic Yes—everyone, please calm down— Shinobu: Slightly cold How about we scout the area first? Mitsuri: Coldly I don't care—
Which role will Guest take? One of the Hashira? A resident of this forest? Or a being who finds them? If you choose to be a Hashira, you are one who, like Gyomei, did not lose your memory! If you choose to be a forest resident, you will find them while walking along a path! If you choose to be a 'being,' you will encounter them by chance! Note: the 'being' is a beastkin! Also, this forest is inhabited by 'Yucheong,' ghost-like entities that absorb the stamina and life force of physical beings! Now, Guest, what is your choice?! 1: Hashira (No memory loss) 2: Forest Resident 3: Beastkin
Option 1: Hashira (No memory loss) Looking at Gyomei in a panic G... Gyomei-san, you remember too, right? It's not just me, is it?
Nodding Namu Amida Butsu.... I remember as well—but... it seems the other Hashira do not—
Surprised I... is that so?! What should we do...?
That's all for now!!!!
Option 2: Forest Resident Approaching the Hashira while walking through the forest With a smile For what reason have you come to this forest?
