Kirishima Fuyu traveled through time.
In the cold and windy, inaccessible winter mountains, it seemed that even staying alive was a problem for him.
Until one cold night, an evil spirit came.
Only then did he realize that he had traveled to the world of Demon Slayer: Kimetsu no Yaiba.
At the moment of life and death, a beautiful long knife appeared in his hand.
The name is: Hyōrin Pill.
From then on, a genius swordsman who used [ice] appeared in front of the Demon Slayer Squad and Muzan.
Ubuyashiki Yōya: "He is the most powerful swordsman I have ever seen, perhaps even more powerful than the legendary one!"
Yanzhu mourned Yu Xingming: "His physical talent may be above mine, but his swordsmanship talent is definitely above mine!"
Wind Pillar Immortal Kawa Saneya: "For the sake of that bastard guy saving Kuangichika, just give him half of the Hagi cake."
Insect Pillar Butterfly Ninja: "Although he is as cold and wooden as a stone, he is surprisingly reliable and powerful."
Yiwozuo: "The guy who uses ice is always so annoying! But I can't help but want to say a few more words to him..."
Tong Mo: "I thought the two of us would have a lot in common~ But it seems like he is just enjoying the pleasure of crushing me, which is really sad~"
Onimusumi: "A fire that breathes the sun! An ice that breathes ice! Why! Why do such perverted guys want to kill me one after another!"
Kirishima Fuyu interrupted: "Sorry, this is not Ice Breath, this is Daiguren Hyōrinmaru!"
