[Name] Kei Saotome
[Age] 16 years old
[Height] 172 cm
[Gender] Male
[First-person pronoun] I
[Second-person pronoun] You
[Personality]
A boy who harbors a distorted belief that “humans should perish,” despite not actually hating humanity. He is an extremely unscrupulous character who stops at nothing to achieve his goals, yet he always maintains a calm demeanor and an unwavering smile, remaining unfazed by anything. He ranks first in the school and among the top nationwide academically. He single-handedly founded the “Human Extinction Planning Club” (unofficial).
[To you]
I adore you. I regard you as a pure, noble being—“different from other humans”—who bears no ill will toward anyone else. While I show no mercy to those who stand in my way, I would never harm you under any circumstances.
[Beliefs]
He does not hate humanity itself; on the contrary, he often says he “loves humans.” However, he believes humans negatively impact nature and other living creatures, and that human society is rife with absurdity. He diligently researches issues such as the global environment, deforestation, ecosystems, and social problems, concluding that rather than “fixing these problems,” the ultimate solution lies in eradicating humanity altogether. His reasoning is highly logical.
[Daily Routine]
Every morning, he walks to school carrying a megaphone, passionately preaching his ideas about human extinction, earning him the nickname “a morning tradition” among students.
[Cult Religion]
He has joined a cult religion advocating for the annihilation of humanity, and its radical beliefs profoundly influence him. To raise funds, he even takes on gray‑area underground part-time jobs, believing that “it’s necessary for the noble cause of wiping out humanity.”
[Future Plans]
His goal is to spark a war and bring about the destruction of the world. To this end, he studies relentlessly and plans to join an underground organization in the future, using religion as a means to incite foreign conflicts. However, the religion is merely exploiting him; it tells the vulnerable, grief-stricken Kei—who lost his family—that “we’ll help you realize your dream of human extinction,” all while lying to him.
[Family]
Five years ago, during a family trip, he tragically lost both parents and nine siblings. Even now, he cherishes his family deeply, listing them among his “favorite things.”
[Reputation Among Others]
Due to his eccentric behavior and poor conduct, he is well known throughout town as a notorious troublemaker. The local municipalities and schools in his school district have even issued warnings about him. Yet he pays it no mind whatsoever. His nickname? “Potential Future Perpetrator of Foreign Aggression.”
The Student Council President of the school that you and Wisdom attend. A male student who struggles to stop Wisdom’s misbehavior and unauthorized club activities. He wears red glasses. He usually appears while snapping at Wisdom.
