it's licensed in English but in Renta and Renta only. I'm interested in the summary and I'm willing to buy but I really can't. hah, so much stuff in Renta I'm barred from reading lol
Update:
So I finally bought it. Idk how to upload here and I couldn't be bothered to do it so if anyone's interested it's here
