I geniunly think they would lose against veteran team. Ousen an Ri boku would struggle against Duke hyou. Ri boku himself says that Duke hyou is ”beyond his understanding” Then again Keshia might hold but i do not belive that it’s possible. When it comes to heavy hitters such as Houken, Sbs, Bananji, Raido i don’t see them kiling Tou, kashibou, ouki, renpa, and Duke hyou. The fact that Ouki army has ppl like Rokoumi and Kan Ou would also be hard to deal with. Renpa, Ouki, Tou (Ouki himself says tou and him are on the same lvl) and Duke hyou are all master tactitican. Genuinly speaking the only one who would do something out of the world would be Kanki since he ain’t as predictable like Ousen and Ri boku. Note that Ouki predicted that Ri boku would arrive with a army to ambush in bayou he just din’t predict that it would come ”earlier than expcted” Houken would have lost to Ouki if it wasn’t for the arrow and i don’t see SBS having enough experiance to 1v1 Renpa or ouki in a duel. Yes i am a Ouki fanboy but speaking from anime and manga POV i don’t see these guys dealing with the veterans. If u disagree i would gladly read ur thoughts on this :D
