[Showa-era Kamen Riders across generations + Demon Slayer fanfiction + transformation story]
Jiang Chuan You transmigrates into the world of Demon Slayer, but the Breathing Style is beyond his reach.
The Demon Slayer Corps says demons have terrifying regenerative abilities, and the only way to kill them for good is with a Nichirin Blade.
He simply lowers his head and glances at the modified transformation belt rumbling at his waist.
As an Upper Rank demon's Blood Demon Art domain spreads and the Hashira fight desperately...
Jiang Chuan You merely lowers his center of gravity, engine-like breaths gathering in his legs.
"Your fight is impressive."
"But the ultimate way to slay evil, "
"Is the Rider Kick, passed down from hope and the depths of the soul!!"
I expected that the value of the Showa Knights would be weakened. After all, any one of the Showa Knights can be used to kill demons alone. The weakening also makes it easier for other Showa Knights to appear. But in the part where Muzan asked the protagonist to kneel down, I remembered that wouldn't imposing orders only work on ghosts? However, if you put these two points aside, the overall story is still good, and the plot is handled reasonably well. Let's see what the author will write next.
