Since we seem to have a shortage of young passionate detectives around I'll give it a shot.
Sazanami passed out from low blood sugar due to the face that she hasn't eaten in three days. The culprit is Akagi who killed the admiral dead with murder since with her being a flagship, he was the only one who could stop her from eating just...everything.
Akebono has just realized that if Akagi finds an unconscious Sazanami she'll eat her too since the black hole that is her stomach has no bounds. Ushio is distraught over the loss of her admiral and has recently realized that Admiral has also married (provisionally) Oboro in addition to herself. During Akagi's binge eating she also ate Crab-chan , the trauma from that loss along with her admiral-husband (provisionally) has left Oboro shaken to the core.
