Demon Slayer: Transform into Murata, Starting with Breath of Time

An ordinary young man traveled through time and became the "Immortal Murata", a supporting character known for his "tenacity" in "Demon Slayer: Kimetsu no Yaiba". At the beginning, he is chased by his ghostly best friend. He had no talent for breathing techniques, but he struggled in the dojo for two years and still couldn't get started. He unexpectedly understood the breath of time and space. From then on... He held a black sword and embarked on a journey to subvert the world of demon slayers! No, brother Wuhan, can you bear this slash across time and space?
