PSO2 NGS: Urgent Quest: Co-Op Starless Suppression Op

Brand New Starless has arrived. This time is a duo boss quest time
the TLDR is that you have to beat both bosses within ten seconds of each other. Basically if you beat one of them you have to beat the other before it gets back up with half its hp back. Not to hard. Not too easy. Best to do it with a team that knows what to do overall.
