Licensed in English in lots of places, including Inkr ("You Are My Princess") and Renta ("You're My Princess). I've bought it all on Inkr. Inkr and Renta have different translators, these are the Renta officials. Both translations are about the same quality. Ch. 5-5.5 pg. 41 is the only thing that's Renta only.
