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.

Juuzou Oogami is a legendary hitman who has never failed an assignment, no matter how impossible. One day, after wiping out a powerful organization, he is stung by a mysterious wasp and collapses. When he wakes up, the fearsome 39-year-old assassin has been transformed into a 13-year-old boy! Before he can even process what happened, his boss delivers a new order: “In that body, infiltrate a middle school.” What awaits him is an unexpected school life filled with colorful classmates, youthful chaos, and looming danger. Can Juuzou ever return to his original form? Or will the assassins closing in on him end his second life before it even begins!? (Source: Official Site)
