This is severely overdue at this point, but as of today they’re actually on sale, so why not just do it anyway.
Should also check back to the latest Watamote release too, since there has been some updates.
Once again I recommend Honto or CDJapan with SAL shipping (2-4 weeks), or EMS (1-2 weeks) if you can afford it. The latter over the former if you can’t into runes. YesAsia can screw you over with shipment times. AmazonJP should be avoided unless you like paying 3x the price of the book for shipping itself. I have no idea how SE’s store works, but it’s advertised so I included it this time.
Remember to support manga/authors you like!
