This is the 4th manga in the series. Unlike the other two, I wouldn't read this as a stand alone. Many references one can only understand if they read the last 3. These references and back-knowledge are important to understand whats going on.
I've been dying to read this, because I believe that this is the best of the series. I still think so (so far), still have one more to go, so we shall see. So much is going on, but I love every second of it.
I especially love the number of flashbacks that are showed. Awesome and the little cute, romantic scene between Hotarubi and Yashamaru. Super cute! The flashbacks are really bittersweet though, because you really wish the treaty was never broken by the corrupted politics. Damn them. Things had been looking up for both clans with the engagement between Oboro and Gennosuke. Meh.
This manga also was bittersweet, because a couple really awesome characters are slain. I know its gunna happen, but I still get upset when it happens. I especially am bitter, because one of my least favorites has a hand in the killings. >_> Stupid tragic manga....
ANYWAYS....
This is and was my favorite of the series. So much going on, but it's just so good. I can't say more without spoiling it. I do believe my favorite parts of it are the flashbacks. So bittersweet. *sighs* Well, I shall HIGHLY recommend this manga to those that love this genre. So fantastic. I wish it was more popular, because it does deserve the attention. It really does. In the end, I shall stamp this with 5 stars.
Favorite Character(s): Gennosuke, Koshirou, Hyouma, and Saemon (awesome power)
Not-so Favorite Character(s): Oboro (meh), Tenzen (asswipe), and Kagerou
