The next thing was much simpler.
Nedis gave Yukinari a proposal to immediately cut off the delivery of supplies to Kumu Yu from River Home. This would cut off their combat effectiveness.
Yukinari had already been misled by Nedis to believe that the person handling the front lines, Kumu Yu, was an enemy.
Kumu Yu was treated unjustly. He actually did not have any alliance with Nobunaga. However, Nedis' guess was quite accurate at the fact that Kumu Yu did not think highly of the playboy, Yukinari. If the person giving him orders was Koichi, he might have immediately responded. However, Kumu Yu did not feel happy with the weak playboy giving him orders. On top of that, the Roland Army was approaching and could be used as an excuse to delay. Once a winner between Nobunaga and the playboy emerged, he would be able to return with a high position and be greatly valued.
