Best advice for this fight, be patient and react properly to his moves as opposed to being aggressive in his first fight. For example, the overhead slash after a sweep perilous shouldn't be dodged or avoided, he changes it up to a jump slash if far away or a ground sweep when strafed behind but will net about four or five hits if done properly (1-2 slashes while holding sword up, 2-3 after dropping). There are also some risky but rewarding (2-4 hits) dodges like with the gunpowder after the combo and if you deflect his shuriken in his shuriken to heavy slash dash, both requiring perfect timing. Both perilous attacks are easy to read, if he's in your phase, he'll never thrust, if his far away, he'll run in to sweep attack first. The second phase flaming owl throw is the best punish for the mikiri counter, keep a relatively medium range, jump over the owl, and just wait for his thrust attack. Great fight, really tense and very ninja vs ninja like.
