@yumehi I can't describe the joy I felt reading about your plans to translate this manga. NtK is a uniquely relatable series and I'm sure all of us here know exactly what I mean, so to see such a one-of-a kind manga not go to waste is just wonderful. Thank you so much for picking it up, and I hope you find the translating process rewarding.
As for crediting me - the raws I picked up from a user named Ginginc on the old site for the translator for the previous Nana To Kaoru series - https://nanachanscans.wordpress.com/ . If you want to credit someone, definitely credit them, instead - they paid for the raws with their own money when they came out in Japan! (I should have mentioned this - I thought I did, but evidently not!) You should probably thank them or let them know on that site, as they clearly do not come here. In any case, any gratitude is owed to them, not me.
They has also kindly provided a link to chapter 13!

Once again, THANK YOU SO MUCH for your efforts to translate this. I can't wait!!!
