I Just Want to Fall in Love, but I Developed a Multiverse

Kamishiro Yu, an ordinary high school student, whose highest ideal in life is to have a vigorous love affair. Until my mother's last words before the hospital bed, and the dying World Tree sapling in my palm. [Countdown to withering: 73 days] [Warning: Insufficient energy, please feed immediately] He discovered the truth about the world: Human beings are natural sources of energy, and their emotions, desires, and obsessions are all "feed" for the World Tree. As long as humans become stronger and the quality of their souls improves, the feed will be upgraded. And he is the only owner of this farm. "Then let this world," the boy smiled at the Tokyo night sky, "burn for my love script." This is a brutal breeding competition that spans the multiverse. Countless "breeders" are competing for space, cultivating civilization, and harvesting souls. The winner becomes the master of the multiverse. Those who lose will become others' fodder, as well as their farms. "Interesting." The young man wiped the blood from the corner of his mouth, and the shadow of the World Tree behind him covered the sky and the sun. Yukinoshita Yukino's Ice Crystal Kingdom unfolded on the left wing. Chika Fujiwara's life network covers the earth. Misaka Mikoto's thunderstorm tore through the sky. Further away, Shinomiya Kaguya's flames, Kasumigaoka Shiu's dreams, Eiriri's creations - countless lights he "raised" are lighting up. "It seems that just falling in love is not enough." He announced to the billions of monsters that descended, to the countless peeping breeders, and to the entire multiverse: "I'm going to turn you all into—" "The guest table at my wedding." So, welcome to Kamishiro Yu's breeding farm.
