In my opinion, samurai should have some defensive abilities. After all, they are elite bodyguards with a strict code of honor. But Kabukimono are rebels; it suits them to rush into the thick of battle.
Also, it's not very clear why a creature with fixed damage should have Endless Might (immunity to Weakness), if it doesn't affect it anyway.
The names were taken randomly and need to be changed. By the way, I never considered samurai to be bodyguards; in my opinion, they are just vassals. There won't be any defensive abilities; the Shark Guardians will be responsible for defense
