"Nezuko is my sister. I'll never hand her over to someone like you!
True familial love was never something you stole from others. It was something you maintained yourself. Even if you cunningly seized that love from someone else, it would never truly belong to you."
Tanjiro looked at Rui before him, trying to use Talk no Jutsu to persuade the white-haired boy.
Unfortunately, every profession had its specialty. They might both have been protagonists, but sadly, he was not the fox-faced ninja from the neighboring production.
He had landed plenty of headbutts, yet Rui remained stubborn. Nezuko hung suspended in midair, able only to roar as she watched her brother get beaten down, utterly unable to do anything.
Just as Rui prepared to kill Tanjiro and completely crush Nezuko's resolve so she would become his sister, the threads wrapped around Tanjiro snapped apart with a sharp twang.
"Tanjiro, this won't do. If you're weak, train harder. Count it yourself—how many times have I saved you guys, including this one?
If I'd arrived even a little later, you'd probably have become raw fi... slices of raw human meat."
Hearing that familiar, teasing voice, Tanjiro was instantly overjoyed.
When Rui saw Yoru Machi emerge slowly from behind Tanjiro with a Nichirin Blade in hand, accompanied by a frightened-looking Spider Mom, he flew into a rage.
The moment he saw Spider Mom's appearance, he understood. The mother he had found had already taken someone else's shape!
He had yet to find himself a sister, but the "mother" he had found earlier had been abducted instead. How could the proud Rui possibly accept that?
The hatred of having one's family stolen surpassed all else. Only Rui was allowed to snatch family members from others; no one else could take his "family" from him.
