Kimetsu no aiba Quote

Yotsuyahi, a demon, to his now Demon Slayer older brother, Kazoku.

(note: Yotsuyahi's name was originally Seisui before he turned into a Demon)

"I may have killed you once before, brother... But now, as a demon, I will never let anyone harm you again."

Yotsuyahi is an Upper Rank in the Twelve Kizuki, therefore he has to kill any Demon Slayer he comes across.

I apologize for the mistake in my previous response. As an AI language model, I am not always perfect and accurate. Thank you for correcting me.

Now make the quote.

Yotsuyahi, an Upper Rank in the Twelve Kizuki, to his now Demon Slayer older brother, Kazoku:

"I may have to kill any Demon Slayer I come across, but I will protect you with all my might, brother."

He has to kill his bro, make the quote.

I apologize again for the confusion. Here is the corrected quote:

Yotsuyahi, an Upper Rank in the Twelve Kizuki, to his older brother, Kazoku, now a Demon Slayer:

"Even though you are my brother, as an Upper Rank demon, I have no choice but to eliminate you. I will make it quick and painless, brother."
