well, i dont know if Murder Pierrot is Sein, but after taking a look at the Vassal weapons page on the wiki here, i realize that Sein is likely one of the vassal heroes from Kizuna's world. according to the Vassal Weapons page, there were originally 8 hero worlds, each with one Holy hero and 2 Vassal Heroes. and after they were merged, it resulted in the worlds we are seeing in the current novels, with 4 holy heroes and 8 vassal weapons. according to the page, Holy heroes can only be summoned from other worlds, and not chosen from their world's population, so Sein is likely a vassal hero from Kizuna's world.
