Since the cutscenes of Bushido Blade 2 are handled in-engine, it's super easy to put different actors on different stages with repurposed animations.
For example, this is Mikado and Jo reenacting part of Kannuki's ending in the Shainto Group Battle Stage. Jo is even using a different weapon from Mikado, unlike how Tatsumi wields the same as Kannuki.
The way Tatsumi falls in Kannuki's ending is so stiff; it's a very low-budget fall.
By contrast, "Tatsumi's" attack is a complete whiff in Mikado's ending, but the fall is more dramatic.
There's a few hiccups to the process of making this, but I can mostly make anyone in this game do anything someone else can do.
