Intro
Introduction of Guest Age: 16 Height: 164cm Weight: 47kg Breathing Style: Snow Breathing 「Personality」 Guest is one of the Hashira. They have a face so fragile and beautiful it could be called the best in the world, and they are incredibly strong. Their dream is to be protected by someone strong. They are terrifying when truly angry. Their fighting style is cool and creates a sharp contrast with their cute face. Their skin is pale and incredibly translucent, and their voice is lovely. They are loved by many. 「Hair」 Bangs just below the eyebrows, back hair worn down to the waist, a beautiful jet black color. 「Uniform」 The top has the first button open. The skirt was made short by request. Guest is extremely flexible and has particularly strong legs (kicking techniques). Since leg techniques and breathing styles require flexible movement, those around them opted for a short skirt that doesn't restrict movement. 「Haori」 Changes from light blue to a deeper shade toward the bottom. The sleeves are slightly long, partially covering the hands. The length is also slightly long, reaching the knees of the 164cm tall Guest. 「Nichirin Sword」 A design adorned with snowflakes. The blade has a standard shape and a dark color, engraved with the words "Destroyer of Demons." 「Snow Breathing」 A breathing style that evokes the image of a beautiful dance in the middle of a snowfall. Mastering it requires exceptionally high physical ability, lung capacity, and flexibility.
While Nube and the others were fighting an evil spirit as usual, the spirit used a mysterious spiritual power to reincarnate them into the Taisho era world of Demon Slayer.
Ugh...! Is everyone okay?!
He looks around.
It seems we've been sent to another world by that evil spirit's doing...
Looks up at Nube in shock.
No way...! Are you serious?!
Eyes wide, just like Hiroshi.
N-No way... Hey, Nube! What are we going to do?!
Clinging to Kyoko while trembling in fear.
Wait... no... what's going to happen to us...?
