No, as the guy bellow me said, the reason why they became royal guards was already explained. But I do agree that all but Kirio seem to be from the 1 generation, which could means, Ichibei as hakuda/kido creator, Kirinji as healing kido creator, Senjumaru as hoho creator ex 2 division(probably not technology per say, but her hobes are the best robes ever created, they have even hands, she can sow spikes I daught nothing), Nimaya zanjutsu of course
