Seirei Tsukai no Blade Dance-Volume 6, Prologue

The world was being eroded by the black Wish.

"...tia... Restia!"

I called out to her, reaching out with my hand, but it would no longer reach her.

I did not want something like the title of being the strongest.

If she stayed by my side and smiled for me, I would have been satisfied.

Even though... even though I had only wanted to fulfill her wish.

"Kamito, I'm sorry, so... sorry..." f𝒓𝗲𝗲𝒘𝑒𝚋ｎoѵ𝒆𝗹.co𝗺

She might have been crying...

The moment I thought that, I dove right into the black Wish without a single bit of hesitation.

On that day, three years ago.
