If you liked Blue Dragon, Naruto, and Bleach, you will enjoy Beck. The Mongolian Chop Squad are actually a group of inmortal assassins, dating back to the time of Genghis Khan. Due to a spell put on them by a rival warlord, they were condemned to an eternity of wandering the Earth, their souls lost to darkness, searching for a way to reverse the curse.
Fast forward to modern-day Japan.
Now posing as a band called Beck, the warriors get a lead that could change their fates and head to America to find a way to undo the spell. What'll follow will be a journey paved with violence, blood, magic, romance, ancient mecha, and some amazing fights. I don't wanna spoil it, but when Koyuki gets in the Yngwie to fight Yoshiyuki, it rivals even the Naruto vs Sasuke fight. Get this anime, you won't be sorry.
