Since both Akatsuki and Shiroe died, they had to give up a part of their memories. Well, at least we saw that happen with Akatsuki. I wouldn’t be surprised if Shiroe managed to somehow keep his, but that’s just a theory.
After coming back, Akatsuki realizes that she needs to put more faith in the people around her. Rather than trying to do things alone, she and Lenessia ask the others for help. Rieze is willing to share with Akatsuki the 8 Teachings that the D.D.D. is aware of. Hopefully Shiroe will learn to trust those around him more as well.
