The war continues...
The six Zergs with Royal rankings went up against Adjutant Kir von Giselle and Dean Frey von Gregory. As there are only two of them, it was difficult to repel every onslaught without utilizing their divine powers. The world itself normally forbade them from employing their original strength, but after getting approval from this World's Heavenly Laws, their constraints on their souls were lifted. The only thing they need to watch out for is their vessel overloading and collapsing from the extreme disparity between their body and soul.
Only by expertly managing the divinity housed within their body can they ensure that their vessel won't burst. The two of them were sufficient to repel the Royalty of these Zergs despite their restraint, but their bodies were unable to withstand a single blow that would have killed them.
