I, Kira Yoshikage, Just Want to Live a Quiet Life

My name is Yoshikage Kira. I'm 17 years old and single. I live in Apartment 401 in Beika Town and attend the prestigious Shuchiin Academy. I pursue a calm, uneventful life like a plant. I don't smoke, I only take the occasional sip of a drink, and I go to bed at 11 p.m. sharp, getting a full eight hours of sleep every night. My classmates and neighbors say I'm "a reliable, if somewhat distant, nice guy." That's the script I wish I could live by. I don't need delirious joy, and in return, I won't have to face despair. I want to live a quiet life with a heart like a plant's. That's the kind of stable life I'm after. I don't need any twists or turns. Just something simple. Something anyone can take for granted. All I, Yoshikage Kira, want is an unerring, peaceful daily life that satisfies me. But... Kotonoha Katsura; Ms. Satou Matsuzaka; Yuno Gasai. Fujino Asagami... Ms. Yagami... Ms. Ryugu... Ms. Yukinoshita... You're all such a nuisance. What's so strange about that? You're the ones who should be going crazy! Why do you come near me? Why won't you leave me alone? Why do you force me to... kill you!!!!
