2P!Japan's POV
I wished I could say that I wasn't already used to any of it. None of what I saw was particularly new to me, and nothing really got to me. Seeing Tokyo in ruins might have been upsetting to me at first, but the circumstances were the same as during the Second World War. I had been tasked with helping the citizens of Hiroshima and Nagasaki recover from the intense radiation. I remembered hoping that I would never have to see what I had seen then again. It didn't turn out that way, unfortunately. At first, I refused to leave home. Even though there was no home for me to return to, I said that I would rather die than leave. Things didn't go that smoothly, so without much hope left, I was forced to leave for the mainland.
I wasn't exactly certain of where I was going, but I knew that there was no going back. All I had that reminded me of home was my katana, and that was one thing that I had turned peddlers down over. Maybe I could have gotten more food or water if I had given it up, but I had already sworn to survive a different way. I would occasionally raid supermarkets for food, avoiding fellow survivors if I could. After all, only large groups of survivors and solo survivors with death wishes would dare to enter the supermarkets. The reason was that they were where the particularly dangerous people made their habitats.
Sometimes, my raids went swimmingly, and I'd make off with more than enough supplies for one survivor. My most successful raid was not too long after I had set foot on the mainland, and I had gotten so many things that I had to steal a cart to carry all of it out (none of the other survivors noticed a thing). Other times, I had to run for my life with what I could carry because they'd catch me in the act.
About one week from the last supermarket raid, I had exhausted my supplies and entered another supermarket with my cart so I could get a few more things than last time. It should have been a quick trip, but some of the survivors who had claimed the place caught my eye. I took my katana, abandoned the cart temporarily, and silently followed them to a large group that had gathered at the back of the supermarket.
"What are they...?" I tried to get a closer look at them, but since I risked certain death if I was too close, I took extreme caution. I watched as the group's leader tossed something into the rest of the group. They tore at whatever it was like they were dogs before it hit the ground. Some used their hands, and some used their teeth. Blood stained all of them. I thought that they were just eating some meat at first, perhaps some beef or pork.
As soon as I spotted one of them making off with a human foot, however, I turned away and returned to my cart. I finished getting what I needed to get and left without so much as making a noise or even looking back. I was disgusted and disturbed by the bizarre ritual. I was equally as confused, however; why would they need to eat human flesh when they had so much food available to them? I didn't stay to answer that question. I never wanted to see such a thing again.
