The story's centre is Fuu's search for a samurai who smells of sunflowers. For this journey, she picks up two samurai: a really wild, thoughtless, and violent one who gets easily into trouble, and another one who is tame, mysterious and well behaved.
The three somehow manage to get together and search for Fuu's man. But as they move on, things reveal and they face hardships and battles while a weird type of friendship grows between them.
The two feature an alternative reality, one is more medieval while the other looks more like the Edo period. Although being very different, both have somewhat of a similar setting, featuring three main characters of which one is silly, one is too serious for his own good and the third is a woman who has a certain place she must go to. They also slightly resemble each other in the atmosphere of the series and both have a rather unique storytelling. So perhaps also because of their differences, you might find yourself enjoying both.
The feeling both animations are giving is almost the same. The two are really unique in the ways of their display and the beautiful art and soundtrack. They talk about serious issues, each in its own outstanding way, and take the watchers into an adventure filled with triangles and drama. Beside being very artful, the fighting scenes and different types of martial arts are not falling behind at all, and one may enjoy both because of the great amount and quality of action.
