Common questions

Where does the video come from?

We are a catalog, not a video host: episodes play in partners’ embedded players. Quality, dubs and speed come from them, not from us.

Why do some titles have no player?

It means no partner has it yet. We mark such titles right on the poster so you don’t open the page for nothing.

How do lists and community tags work?

Lists are yours and live in your profile. Tags come from people: add your own on a title page or vote for someone’s, and the catalog searches by them.

How do I change my nickname or avatar?

In your profile, under “Edit”. The nickname is public and forms your page address; your email is never shown to anyone.

Who can see my profile and lists?

Your profile is public by default, but one switch in profile settings changes that, down to “nobody”. Lists, collections and reviews hide separately. Your email is never shown and no setting can turn it on.

Mahiro Oyama was just a normal erotic-game loving dude…until he woke up one morning as a woman! Turns out his mad-scientist little sister, Mihari, tried out one of her new experiments on him…with a disastrous outcome, as far as Mahiro’s concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing’s for sure…life is going to get a whole lot weirder from here on out!
