It was the twelfth day. Alione, the dog of Komori died from sickness. Kazuki is thinking of eating it, just to survive. For the first time the captain agreed to Kazuki about an idea. The moment Megumi agrees to Kazuki's word, the survivors decide to pick who would butcher the dog. Ritsu lost the game of rock-paper-scissors, thus she needed to butcher the dog. Apparently Ritsu cannot. Kazuki steps in and performed the act after she lectured Ritsu and silenced Chiaki. The 'meat' is cooked well and it fed the living. Thus the end of the twelfth day.
