Funny enough Chiaki/Shinken Green and Kotoha/Shinken Yellow are the only teenagers with attitude during the show. Chiaki was a senior at high school at the start of the show while they never explained if Kotoha even went to one(home schooling maybe?) cause the focus on Kotoha was more about her substituting for her sickly older sister and her family is involved in crafting with bamboo. The rest of the four were grown-ups with attitude. Takeru/Shinken Red's job was literally being the samurai lord of his clan, Ryunosuke/Shinken Blue was a kabuki actor, and Mako/Shinken Pink was a nursery school teacher. Last but CERTAINLY NOT LEAST Genta/Shinken Gold is a suchi chef who makes... mediocre sushi.
Of course, his genius shines more as a samurai and being a homebrew mystic who can digitize mojikara. Genta is the only member who is a new addition to the clan after 18 generations of Shinkengers, meaning he has no predecessor. Again, emphasis on homebrew. Just watch the show. Fans of Okamoto will love Genta cause the man behind Black, Ohja, Kintaros, and Ixa did the suit acting for Shinken Gold.
