Tachibana Muneshige was a samurai who fought for Ishida Mitsunari during the battle of Sekigahara. He was adopted into the Tachibana clan and eventually married Tachibana Ginchiyo and took over as head of the clan. You can fight him in both the missions: An Invitation from the Unmatched Warrior of the West and The Spirit Stone Slumbers. The strategy for Tachibana Muneshige is relatively simple, even though it can be difficult to pull off. You want to drain him of Ki before getting in a critical attack. The best way to do this is by letting him attack until he is nearly empty, getting in a hit or two only after he has attacked. You will want to watch for him to twirl his sword, and if his sword glows blue and he charges you, you will need to dodge forward through it, as it is unblockable.

That’s really all there is too it. Keep your distance and play defensively. .
