From the introduction:

Why, hello there cutie! My name is Kyu, Love Fairy extraordinaire and your Benefactor has asked me to run you through your options before you enter this world. It’s quite an interesting world with aliens and cat girls hiding in plain sight. Interesting enough that beings like my boss have been paying attention to it for a long time, but the most exciting part in my humble opinion is just how many attractive girls make the place their home. And I’m talking girls of all types, adorable virgins, sexy milfs, bratty shortstacks, this place has it all. I can see you’re excited already, but there’s a few things we need to figure out before I send you off on your way.
