You’re welcome 🙂 I’m glad you enjoy it–I was a little unsure on some parts, but I did want to finish up the story so I’m afraid I might have rushed it.
As for Kareru in the future… well. I’m not all that keen on continuing his story at the moment, but who knows? Maybe one day.
edit: Wrote a little bit of older Kareru Uzumaki in this ficlet here!
