Shattered Realities

When the volleyball community's most beloved mated pairs gather to celebrate Atsumu's baby shower, the joyous occasion takes a sinister turn. Thirteen alpha-omega couples-representing some of the sport's most iconic partnerships-find themselves suddenly transported to a sterile laboratory, prisoners of rogue scientists conducting illegal dimensional research.
Among the captives are Alpha Kiyoomi and his heavily pregnant omega husband Atsumu, who serves as the nurturing heart of their close-knit group. Known for his maternal instincts and fierce protectiveness, Atsumu has always been the one to ensure everyone is fed, comfortable, and cared for-qualities that made him the perfect choice to host this celebration. But now, dressed in his carefully chosen maternity sundress and delicate makeup, Atsumu lies unconscious in a stasis chamber alongside Kiyoomi, unaware of the nightmare unfolding around them.
The scientists reveal their sinister experiment: they've been tracking Atsumu and Kiyoomi across the multiverse, documenting how their relationship manifests across different realities. The captive alphas and omegas are forced to watch these alternate dimensions unfold on massive screens, unable to interact or intervene, while their friends remain trapped in induced sleep.
