Basilisk: Kouga Ninpou Chou, Fate/Zero Recommendations
If after watching Fate/Zero you were left wanting more in the way of 'Battle Royale' believable brutality and less in the way of circle-walky talking, then Basilisk is the anime for you!
Instead of Zero's premise of seven masters with seven revived heroes of lore (complete with 'middle-man' pace slowing rules overload) battling it out until only one pairing remains, in Basilisk ninja with superpowers (two sides, with ten on each side) every bit as powerful as those wielded by servants, quite simply, fight a desperate battle to the death; dying in quick succession. You can not get much more intense! In contrast, no-one really died
Both are action anime about a group of people fighting one another to the death. In Basilisk it's about two ninja clans fighting to determine a successor to the shogunate while in Fate Zero it's about seven masters and their servants competing to win the holy grail. Both are action packed, have a fair share of duels, are very engaging and have great storylines. Also, both are very tragic.
