I thought it was cool. Gave us more of a look into Dante's life. It should have had more episodes, but apparently, it's popular to have miniseries.
And I though they could go with DMC style of 20 missions. After the craziness of the game, I think this anime was a breathe of a fresh air about how Dante manage his shop. Too bad it's 13 episode. --- "Another has fallen to my spear!!!" Zhao Yun
