Heavenly Host Club Horror

What would happen if the hosts, Kasanoda, his younger sister, Nekozowa's middle sister and Haruhi's cousin did the Sachiko ritual and end up getting sent to the closed spaces of Heavenly Host Elementary? Can they survive if they're not with their partner? The twins are separated, Tamaki can't find his 'daughter' anywhere and Mori is searching up and down for Hunny. (3 OCs)
