Nope, this Chapter didn't completely tie in everything. They explained the Orichi experiment. That I got. The "soldiers" story, I got that. But what happened to the twin brothers and their people? That story has a lot of gaps, like how and why did things end up the way they did? So many unanswered questions! Lol. It was still, somewhat, a good storyline and great artwork/animation, so I give it 4 stars. I need to see if they have a manga of this so I can read the entire story instead.
