Thanks for the chapter, looking forward to more.
I think it could have been interesting if Ken had actually sided with Madars although it would conflict with his character so maybe changing the end goal a little.
Will we get any explanation from Ken as to why he killed Madara? I really do feel like it would be in his character to do unless he sensed deceit from Madara, which I would find unlikely. Madara tends to be sincere.
