I remember seeing either a trailer for it or a part of the first episode.
There was a guy who tried to commit suicide (I think) and jumped off a tall building. As he was falling this guy and I think 2-3 others kinda fly next to him.
The guy offers him his services to save him or something coz I remember him giving the suicidal guy a card.
Sorry if I didn't describe it very well, but that's a that I remember.
