My stand in this argument is also the same as B214 as it is clear in the previous accounts of Evil Pieces being discussed that there is only 15 pieces but that started to waver when I read Volume 19.

In Top Secret, Belial talked about the pieces while some things were censored out as they were confidential. Also he showed something to Raiser that was also censored out and Belial complimented Ajuka for having created such thing.

That may not be a King piece like you guys think (a High-class Devil has a piece inside him too) as Raiser doesn't know about it but there may exist a King piece that has different capabilities.

TL;DR: My stand is there are 15 Evil Pieces (Q->P) given to High-class Devils but a King piece might exist and its existence is top secret.
