I Save Kanae from the Start and Earn a Knight Compendium

After transmigrating as Tendou Souji, the System throws me into the twilight of Demon Slayer.

Mission objective: Save the butterfly fated to fall.

So, just as Kanae Kochou closed her eyes in exhaustion, I pressed the button on the Kabuto Belt.

Clock Up!

The world stood still, and I shattered the demon's claws with a kick, stopping them mere inches away.

[Fate of Shinobu Kochou reversed. Mission complete.]

[Reward unlocked: Kamen Rider Kuuga, a Spirit Stone Belt containing the power of ancient times.]

When Kanae awoke in my arms, and her sister Shinobu came racing over in despair only to find her safe and sound, I knew that I, Tendou Souji, had changed everything in this world.

It didn't take long for everyone at the Hashira meeting to realize that this man's power went far beyond the scope of Breathing Styles.

Water Hashira Giyu Tomioka: “Why does his ‘Breathing’ make armor imbued with the power of sealing grow over his body?”

Love Hashira Mitsuri Kanroji: “Wow! Mr. Tendou transformed into a different color again today. So cool! C-could you show me the pink form?!”

Meanwhile, Shinobu's smile grew ever more inscrutable, while her sister Kanae regarded me with curiosity and gratitude. “Mr. Tendou, that ‘acceleration’ you used to save me, and all those completely different ‘transformations’ afterward... Could you please explain them to us properly?”

Even their Tsuguko, Kanao Tsuyuri, often watched me with a quiet, intent gaze.

Deep in the darkness, Muzan Kibutsuji raged: “Impossible! That golden impact, the power over time, even the sword that controls the weather... This can't be Blood Demon Art! What on earth is he?”
