Shadow Skill: Eigi

fighting till u drop dead , thats what these both represent , and with a supernatural touch to it were lots of blood gets spilled , only recommended for the mature anime fans 

Both series focus on a warriors code of conduct through a woman's point of view. These fantasy shows also explore aspects of war and contain both a shonen and military themed undertone. Furthermore, both leading ladies also teach their young male companion the path of becoming a warrior. 

Both are about young guys striving to get strong enough to protect the ones they love. Kenichi is a little less well animated but on the plus side has a lot more romance, awesome martial arts teachers and comedy. So if you like training, martial arts and epic fights you may just cream your pants. 

Both are fantasy. Both have great storys. Both have very similar female main characters.
