What is that anime about?
It's about 2 people that fall in love but are on opposite ends of clans. think romeo and juliet, but with ninjas.
anyways as they grow old, they start to have a peace treaty.
and they do show competitions between eachother.
Something happens, and they send letters to each clan letting them know the peace is over.
One of the clans get a hold of it first, and try to stop the other clan member from reaching his clan.
The son/daughter of the 2 people that fell in love, also fell in love. And they are in charge.
With the war about to start where they are on opposite ends.
you see where it's going?
Each ninja has a unique talent/power. And from my experience in watching it. There's only like 2 bad guy ninjas. The rest of them look like bad guys, but when you see their backstory you realize.... they are all not bad people, they are just caught up in a constant hate fueled war.
