Round 1: Tou, high-diff for Tou.
Round 2: Tou, He has the better strategists + the better combatants + having vastly more experience in battlefield. Before Shibashou did his 5k vs 20k against Yan with his loaded army. Tou did 5k vs 50k against Chu with Rokuoumi, Kanou and co, and he survived it. He was getting Choutou & Moubu as backup, but Chu army was also getting thousands of more incoming behind them.
- From a martial point of view Tou has the superior underlings:
- Kyoukai
- Shin
- Ouhon
- Rokuomi
- Akakin
- Kyourei
- Archer Bros
The strongest of these are beating the strongest subordinate of Shibashou, especially when there's no numbers advantage for Shibashou's subordinates. Ji'aga & Kansaro will fall to Kyoukai/Shin/Ouhon (any 2 of 3), Kyourei/Akakin/Rokoumi/ whoever's left from the 1st 3... will be plenty for Fuuon, Gakushou, Jyou Ka Ryou. Then the walking nukes the archer brothers...you can bet your ass Tou is going to make the peak optimal utilization of these two.
- From a strategical point of view he also has the superior underlings:
- Karyo Ten
- Ouhon
- Kyoukai
- Ryou' koku (93 intel stat, essentially Tou's own ChouGaRyuu)
- Shin, the instincts of this mf is way too much of a wild card for anybody on Shibashou's side
- Akakin, one of the best instincts in the series for a subordinate commander
Tou utilizing insane battle formations like he did during the coalition arc with this amount strategical talent? Lord have mercy.
Tou just has the superior tools under him than Shibashou does, while being the superior general with vastly more experience. He should be able to win this battle with Mid-High Diff.
Round 3: Tou, extreme-diff. Great General of Heaven factor + other motivational buffs like unification shit and will shit. Plus, no idea how strong Shibashou is. There's no martial hype that puts him above or below Tou, but I'm gonna give benefit of the doubt to Tou over a new character with non-clarified martial prowess.
