Yoriichi realises a little too late that he shouldn’t have taught you his technique. He should have let you train to be a Demon Slayer and make your own; but with sun breathing now implanted into your system, it’s going to be hard to get you to use anything else.

How unaware you are, his little child. You don’t know of the demons that lurk in the dark; ones of his past, and of your future. How is he supposed to tell you about this when you have so much else to learn?

Perhaps it can wait.
