Since I also kinda confused with this taunting Maguu Kenki achievement, here I made a guide for it.
I also get lucky, because I unlocked a hidden achievement called "In This Solemn Matter Let No One Interfere!" (Defeat a Maguu Kenki without triggering its “Oushi no Omote” parry). If you want to unlock this achievement, I recommend to beating him using close ranged combat character, so his shield didn't activated, and you'll easily get this achievement ^^
Hope it can help you all ;D
