First of all, I recomend everyone to read the manga "Hana no Keiji" before getting into this anime. Thing is that, like a reviewer on this anime here said, it is difficult for many to get into this anime. Reading the manga first will allow you to further understand the concept of this anime. With that said, let me express my review on Gifuu Doudou. Story: 6/10 It was told that Uesugi Kenshin had illegitimate son. The great Shoguns Hideyoshi, Nobunaga and Ieyasu knew of this, but, however, prefer not to spill the news to everyone. The story centers on two legendary Sengoku warriors, Naoe Kanetsugu andMaeda Keiji, and their battles through the Warring Kingdoms era. Kanetsugu was a great general serving Uesugi Kenshin and Keiji was an unrivaled samurai with amazing swordsmanship skills. So basically both of them attained a high rank among the Sengoku Period and the story is about how they've attained such positions. Now, truth being told, the pace is slow. But really slow. It's more talk than action to be precise. The whole series are basically flashbacks of the two warriors. And there's a lot of talking here and talking there, so for those who prefer more action packed anime, then this might dissapoint you. However, in my case, I didn't mind because, like I said, I've read the prequel manga and I clearly like the setting in here because I knew exactly what happened before. However, yes there should've been less talk and more action. Also, Hana no Keiji had some great comedy moments. This anime tries sometimes but just fails in this aspect.

Art 6/10
The art is pretty good for its standards. However, the manga Hana no Keiji had better artwork and this anime fails to catch the epicness of its design. It's not as bad as the Fist of The Blue Sky anime adaptation, but I expected more to be honest. I could give it a 5 but I gave it a 6 because the character designs remind me a lot of Fist of The North Star (the manga's art was made by Tetsuo Hara, the sama mangaka of FOTNS).

Sound: 8/10
The soundtrack is great. It goes from a relaxing japanese melody and then you hear some epic battle music when the action comes. The opening "Samurai Rock" is really catchy.

Character: 7/10
I have a mixed opinion about this one, but I gave it a 7. Having read Hana no Keiji, I knew who Maeda Keiji was and how epic he was, but this anime did not show enough character development of Kanetsugu. He's just the typical good guy in the flashbacks and nothing changed much in his present self. Keiji too had almost none character development here in this anime, but if you read the prequel manga, you'll understand how epic Maeda Keiji is. The rest of the roster is forgetable, the anime only focuses more on these two warriors.

Enjoyment: 7/10
Despite its flaws, this anime is still MANLY! I mean those character designs, masculine attitudes, manly tears, dramatic stories, epic confrontations in the past... It's just MANLY! Like I said, the pace is slow and that's why I give this a 7.

Overall: 7/10
Like I said, the pace is slow and that's why I give this a 7. Please read the "Hana No Keiji" manga first before watching this anime, otherwise you'll watch 2 or 3 episodes and you'll become bored out of your minds. But if you like manly anime with tall muscular men, with drama and manly tears, then give it a go.
