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.

Seven years after making a childhood promise to always be friends, Hayato is reunited with his formerly tomboyish pal Haruki at a city high school–only now, Haruki has transformed into the girl every guy dreams about!
