Doping?

It was obvious that the two members of the Black Fog Faction prioritized their attacks wrong. But then again, no one could blame them since they reacted appropriately when the threat appeared. This threat was none other than Sera whom Satoshi summoned as soon as the match commenced. They knew powerful Sera was, that's why they didn't waste any time summoning their wings and flying up to where Sera was in order to take her down. They could more or less tell that they'll lose if they let Sera run loose.

However, what they did actually backfired on them. Because they focused too much on Sera, they didn't realize that Shoyo were already working on their strategy of beast integrating while Sera bought time for them. More specifically, Shoyo began to squeeze out all his strength and concentration in order to bring out his maximum potential.
