Listen, in light of the newest Gintama spoilers, I have to say a few things about the kind of character that our Zura is. To sum up:

• he’s a main part of Gintama’s comic relief because sometimes often he can act stupidly
• he’s actually a terrorist
• he’s got the weirdest pet/right hand man ever
• Zurako makes for the perfect okama

But the best part is what the summary is actually hiding about who he really is: 

• As a fellow student of Shoyo, he never held anything against Gintoki for his choice to protect Shoyo’s legacy (his students) over Shoyo’s life 
• He even went as far as to tell Gintoki that he wouldn’t let him shoulder the burden of killing their teacher a second time, because he knew how harsh the first time was on his friend

• He fell in love with a widow who lost her husband because of men like him (Jouishishi terrorists) but, instead of trying to convey his feelings to her, he’s just happy to spend time eating her ramen soba and looking out for her without asking for anything in exchange.
• Despite being anti-bakufu, he admitted that he and the Shogun may still have common goals and decided to fulfill their mutual promise after Shigeshige’s death

• Also despite being enemies for most of the series, he helped the Shinsengumi at their darkest hour because he recognized that they were necessary to his goal of saving the country 
• He has many nicknames, like the Noble Youth of Madness or Runaway Kotarou, but to quote Sakamoto: “in order to carry on his family line and to protect his comrades, he fought on and on as a coward. But […] if there was an enemy he had that he couldn’t beat unless he put everything on the line, then you might learn the true name of that man once he sheds his coward skin”

• kinda random point but he’s damn wild when he fights seriously

• in the current arc post time skip, he took on the burden of becoming Prime Minister (”Donald Zurump”), making tons of enemies and experiencing many assassination attempts, still in order to achieve his goal of saving his country

• as a terrorist, he’s actually acknowledged to be even more dangerous than Takasugi

and finally

• according to the newest spoilers, he’s confirmed to be the one who went as far as to disband the Shinsengumi SO THAT THEY WOULD WORK ON REUNITING THE YOROZUYA 

In other words:

he’s the hero we deserve.
