Our team is working hard on getting Japanese Book 4, Natural Japanese Book 4 and English Book 4 out in the next two weeks or so.
In the meantime, if you’re itching to know what the cover for Book 4 looks like, come check it out along with other cool info about our manga on our blog.
Thanks so much for your patience and sticking with us through our first three books! We can’t wait for you to read book 4!
