yk ribuko and sei ideal is almost the same. It's just how they execute it. Ribuko ideal is to make an alliance to all the kingdom to be United and not to make a war anymore. (But the question is for how long?)(with the way his king already has an eye on him because ribuko is more popular than the king. Do you think the king in an ancient times will be willing to accept that your subordinates is well-respected and well-known than you.)(will be feel bad for Kaine if what I think will happen) And Sei Ideal is to fight all the neighborhood kingdom to unite the all of the kingdom to end the war for all.

TBH I DON'T HATE RIBUKO. I JUST HATE HOW THEY KEEP ALIVE HIM FOR 17 YEARS IN MANGA. THE AUTHOR GIVE US A SIDE STORY OF HIS STORY WITH KAINE. AND NOW I DON'T WANT HIM TO DIE AT THE STORY. I JUST WANT EVERYONE TO BE HAPPY. WAR ARE SO STUPID TO BE HONEST
