91 Days is an anime love letter to mafia films. Set in the 1930s when Prohibition is in full effect, its cast is filled with gangsters and bootleggers, led by a protagonist on a single-minded quest for revenge. The haunting opening credits perfectly encapsulate the violent world that Avilio has chosen to inhabit, while showing the psychological toll his charade is costing him.
When I first started the series, I was a little concerned about how much I would like Avilio, born Angelo Lagusa. His father belonged to the Vanetti mob family and was killed along with the rest of his immediate family during a change of power. As a child, Angelo escaped the slaughter and then disappeared for seven years from everyone he knew, only to return at the start of the show because he receives a mysterious letter giving him the names of the men who murdered his family.
