"My name is Aya Yamasaka. I'm starting this diary to record my memoirs. I've included a photograph of myself, taken merely a week ago, to ensure the integrity of this documentation. Though it may turn out to be disadvantageous for me in the long run, I feel that it is extremely important for me to keep track of my actions and mental state for the forseeable future. After all, as of tonight, I am officially a serial killer."
"I suppose I should explain, although ideally I'm the only one who will ever read this. I have... a bit of an obsession. I'll admit, it's probably not the most normal quirk for a girl my age, but at this point it's a bit too late to change myself. Through a series of unorthodox circumstances, I've found that I possess the rather unique ability to swallow people whole. Real, human people, literally inserted into my stomach via my mouth and esophagus."
"It all began two months ago, after a perfectly normal day of my college classes and work at my part-time job. As a lowly undergrad, the only 'academic' job I could land was as a lab support assistant; in other words, a gopher for all the actual researchers. That afternoon, I had been assigned cleaning duty along with a girl named Saki. Saki was... a bit of a B word. Pardon my French. She had very few social connections due to her frankly irritable behavior and awkward temperment."
"Despite the fact that we had had very few interactions before, we quickly got into a dispute. She began to get physical, and she pushed me into a nearby broom closet. Imagine my surprise when, instead of assaulting me, she began to kiss me! She was holding me tight, pulling at my clothes as if they were the packaging on her favorite snack. I was taken aback by her advances, and in that crucial moment, I tripped. I fell backwards, and Saki fell into me. Into, not onto. Her weight and momentum pushed her head into my mouth. I panicked, and my natural instincts took over. All I could think of was to swallow, so I did. I kept pulling and pulling, until Saki was entirely gone, and I was left alone in the broom closet with a stretched, struggling gut."
"Saki didn't last long after that. I hid, locked in the closet in a deserted school, praying that nobody would find me digesting my would-be rapist. I suppose I could say that the wait was agonizing, as I slowly extinguished a life inside of me. But I can't, not really. The point of this diary is to document my true feelings, no matter how monstrous they may be. The truth is that I enjoyed every minute of digesting Saki. I'd never experienced anything like it! I could feel her feeble struggles lightly stretching my skin. I felt her warmth flowing through my entire body. I knew, for the first time in my nineteen years of life, that I had complete domination over another human being. She thought that she could help herself to my body, and now she was nothing but sizzling, melting meat."
"Only afterwards did I realize the severity of my actions. I swore to put that day behind me, and to never again take the life of a human being. But every night, I remembered that feeling of ectasy. I could not forget the sensation of devouring Saki, of killing her with my own innards. It (pun not intended) ate away at me. Eventually, I found myself looking at my classmates and seeing meals where I had once seen friends. The second incident occured as a result of this daydreaming. My 'condition' began to affect my grades. I could no longer focus on my studies. It was as if a hidden, predatory instict had awakened in me. Whereas before I was near the top of my class, I could now no longer bring myself to care about academics. All I desired was food."
"There was a very beautiful girl in my year named Ibumi. For the sake of decency, I will not record the full details of my thoughts on her body; suffice to say, the mere sight of Ibumi often reminded me that I am extremely homosexual. She was respected by many of our professors, as her grades were high enough to put even my own to shame. Ibumi and I shared many classes together, so we often had short chats during downtime."
"Despite my best efforts, she noticed that I was having sudden difficulty with our coursework and graciously offered to meet me at my house so that we could study together. I knew then that I shouldn't accept, that I should keep her as distant as possible, but I couldn't refuse. Here was the tastiest-looking girl in the class, asking to come home with me! She met her end that night. I grotesquely murdered her inside my own body, just as I had done to Saki. I couldn't even begin to describe her face when I forced myself onto her, but I could write a novella on the sensations she provided me as she broke apart."
"I woke up the next morning feeling nothing but regret. Though I knew I was still in the clear, as I left no physical evidence of my crime, I still could not help but feel guilty. Ibumi had wanted nothing but to help me, and I had devoured her. She was gone, and hadn't even left more than an inch or two on my waistline( As a sidenote, I should probably look into this, as it appears to violate the Law of Conservation of Mass). Still, my second predatory experience had been every bit as fulfilling as the first. As much as every bit of human nature in me told me that my actions were abhorrent, something stronger, more primal urged me on. I wanted to stop, but I needed to eat more. As fate would have it, my decision was soon to become much simpler."
"I had slipped up in a big way. I was so caught up consuming Ibumi that I had forgotten my bedroom window was open. I was in a second-story room, and we hadn't made much noise, so I had assumed that nobody would have cared to look up. However, in the house directly adjacent to my own lived Chitoge, a friend of mine since childhood. Her own bedroom was directly across from my own. This detail will, quite obviously, be relevant later."
"I feel that it's important to note that Chitoge looked up to me, even to the point of attending the same local college as me. She's a full year younger than me, so I've always been something of an older-sister figure to her. It's fairly clear that I failed in that role, though, as she fell pregnant some seven months ago. Still, she was a good girl with good mannerisms and good grades and good friends, which is why I found it strange when she began behaving oddly around me."
"At first, it was just awkward glances at me in the halls between classes, like she had completely forgotten how to greet me with her normal sunny smile. Then it progressed to avoiding me entirely. It wasn't until this very morning that she knocked on my door, nervousness writ plain on her face, and asked if I would skip my classes for the day and stay home with her. I agreed almost automatically, inviting her in and locking the door behind her before reason could set in. We made it to my bedroom, and despite my rather unladylike drooling, I kept up my image of a mature, capable woman that she could always confide in. That is, until Chitoge uttered those two words that sent me reeling. They weren't 'I know' or 'I saw' or 'You monster'. No, my pregnant friend that I had known for as long as I can remember said,
"Eat me."
"I was dumbfounded, of course. Here I was, struggling not to devour the innocent, beautiful girls surrounding me every day, and now Chitoge was offering herself to me? She broke down and confessed that she had witnessed me devouring Ibumi a few weeks prior, and that she now wanted nothing more than to meet the same fate. Chitoge professed her love for me, and told me she wanted nothing more than to give up her body for my own pleasure. She desired nothing more than to please me. It was all she lived for. Even her pregnancy, she explained, was her way of trying to appeal to me. Chitoge was the only one I had ever told about my particular attraction to pregnant girls, but I never would have imagined she would allow a stranger to knock her up just to make herself nicer to look at." "Chitoge stood before me, sensually undressing, teasing me with the sight of a body I had seen hundreds of times before. I wanted to tell her no, that she was more than just food, but I couldn't. Chitoge taught me today that perhaps, my ability is not inherently evil. Perhaps there's nothing wrong with eating other people. I accepted Chitoge's offer today. I swallowed her whole as she shoved herself, naked, down my throat. I cherished the feeling of her distended pregnant midsection making a giant bulge in my throat as she slipped down into my gut. I experienced, for the first time, a massage from the inside, as Chitoge lovingly rubbed at the inside of my stomach. I could hear her moan in ecstacy as my body's enzymes burnt her flesh. She squealed and tittered happily with as she was tossed around by the rhythmic undulations of my stomach walls. I could feel each exact moment her softening bones and dissolving tissue snapped and a limb fell off her broken body; yet despite being buried in her own dying flesh, all I could hear from Chitoge in her final moments of consciousness were the sounds of orgasm (presumably, anyway; I will neither confirm nor deny whether I am still a virgin)."
"As I write these words, this journal is perched atop my belly, which is hard at work processing and squeezing away at the meaty sludge that was once my beloved neighbor. I can feel her separating; my intestines are eagerly (and noisily) pumping her melted flesh downward, while my stomach clenches and mashes at the chunks of Chitoge's body that are still relatively solid. Despite all this activity, my gut is still a fairly decent desk."
"I came to an important conclusion, writing all this down. Since, after killing three people, I am now considered by most definitions to be a serial killer, I'm a doomed girl anyway. However, I've always been a slave to my own academic curiosity. So, I've come to a decision. I'd like to keep eating people. I want to keep hunting them down and devouring them, for as long as I can. The world has never seen someone with my abilities, so it'd be a shame not to explore their full potential, right?"
