 If you liked Durarara!! |  ...then you might like Berserk: Ougon Jidai-hen I - Haou no Tamago |
Both stories revolve around supernatural elements minus the setting which are the main focus of both plots. Also one char has a rivalry with another char. I find some of the characters to be similar though: Shizuo-Guts Izaya-Griffith
