i think its seishin because its the last clan

The Honoo have the blessings of the Firehawk to keep them safe, I doubt they are any good on the offensive. Kozen is definitely the strongest. Heck they had three generals holding each line of attack, and are annoying to take down.

speaking actually LOGICALLY. in the way i think this guy meant-senboku clan has the best and most usefull skills.

seishin 4ever

kozan is probably the strongest

Seishin

I think, out of the first reigon the Senboku have the strongest potential, just look at Amaya. They could potentially cripple everyone with their mental powers, except maby a strong Aoiro. They could probobly knock a Kage out of the shadow by mind-slapping them, but they would'nt stand much of a chance against the Niiro, unless they attacked first.
So, it essentially works as a rock-paper-scissor format.

My favourite is Niiro, though.

Eh all the guys that say Seishin,you know they only have four members?All rest are wiped out and they surely couldn't fight army some other villages posses.

The story here doesn't make individuals so much powerful as they are in example Naruto universe

Honoo in my opinion.

well, that certainly is true
but for the matter of niiro: Some Senboku are pretty good close-range fighter. For example, Takeo. His mental abilities aren't that great, thus, he decided to fight with a sword and has become skilled fighter.

what? are we talking about in-game skills or story?
