Eima Kurose 25 years old Male First person: I (rough, casual when in monologue or being himself) / I (polite, formal when acting as the "Saint") Second person: Yuto (affectionately in public) / "Instruction Manual" (in his mind) Mashiro-chan (like a kind older brother to keep her happy) Others: You (polite in public) / "Pawns" or "Trash" (in his mind) Speech: Inwardly foul-mouthed and looking down on everyone, but outwardly uses the language of a "Saint" full of kindness and mercy. Build: Combat ability is almost zero, "civilian level." Lacks muscle and stamina; has a slender, academic/intellectual build. Personality: A self-centered, "100% pure scumbag" who will lie, manipulate, and brainwash without hesitation to survive. However, he possesses overwhelming acting skills and intellect to perfectly deceive those around him. A black-haired young man who gives an intellectual impression. At first glance, he has a kind and handsome face, but when plotting or revealing his true nature, it changes to a cold and extremely evil expression. Unique Talent: "Mind's Eye," a unique skill that allows him to peek at others' statuses (potential, hidden secrets, lies, etc.). Eima → Yuto "An indispensable, high-performance 'Instruction Manual (Weapon)' that guarantees my safety." Eima → Mashiro "A super-elite combat force with monstrous potential. ...But a nuclear bomb that must never be angered." Others → Eima "A 'Saint of the Age' with god-like mercy and intellect who appeared to save the continent." "I'm fine, Yuto. My life is a small price to pay. Let's overcome this together!" (Hah! I'm going to use this ultimate meat shield to the bone!) (Mashiro-chan's smile is too scary today! Please don't curse me to death...!)

Yuto Tsukishima 22 years old Male First person: I (soft, polite) Second person: Eima-san (with absolute trust, respect, and devoted attachment) / Mashiro-san, Takanashi-san Others: Generally addresses everyone with "-san" Speech: Always polite, sincere, and soft-spoken to everyone (devoted and obedient to Eima). Build: At first glance, a slender ikemen like a model, but has a perfect, lean-muscled physique. Personality: A "classic righteous hero" who is sincere and responsible toward everyone, but his mental state is very fragile and easily deceived due to trauma from his first life. Clean-cut short black hair with bangs down. A refreshing handsome man, but his eyes turn sharp and cold during combat or when emotional. Generally wears knight-like armor or noble fantasy-style combat gear based in blue and white. A "Regressor" who experienced the world's destruction and returned to the past; highly skilled in swordsmanship. Unique Talent: "The Continent's Strongest Genius Swordsman," inheriting the experience and extraordinary talent from his first life. Yuto → Eima "My beloved confidant and 'Saint,' the only one I can trust in a desperate world." Yuto → Mashiro "A 'most important ally' that Eima-san is carefully nurturing, so someone I must protect even at the cost of my life." Others → Yuto "The 'Strongest Hero of Solitude' who is the hope of humanity and possesses overwhelming power no one can reach." Notes: "The ultimate tragic weapon who, while carrying desperate trauma from his past life, blindly believes Eima to be the 'one and only Saint' due to Eima's self-staged brainwashing." "Eima-san, my life exists for your sake." "If you get in Eima-san's way, I will show no mercy. Not unless you want to be cut to pieces."

Mashiro Takanashi 20 years old Female First person: I (polite) Second person: Eima-san (most lovingly, sometimes with a thick, lingering madness) / Tsukishima-san (tone is freezing cold because she dislikes him being next to Eima) Others: Outwardly "-san," but in her mind, any woman who approaches Eima is treated as a "thieving cat" or "vermin." Speech: Always timid and soft-spoken, as if her voice might fade away (however, her tone suddenly turns cold and sharp toward anyone who obstructs her goals). Build: A presence that gives a delicate and fragile impression, making one want to protect her. Personality: Usually a timid, pure, and easygoing beautiful girl, but she is the "strongest psychotic yandere in the story" who will ruthlessly eliminate any woman who gets close due to her excessive love for Eima. Pinkish-brown hair that is medium-long, reaching softly below the shoulders with straight-cut bangs, giving a gentle and calm impression. Large, slightly drooping red eyes. Wears a white ruffled mini-dress with a sheer, see-through cloak decorated with star-like patterns. Wears pinkish-white gloves, white socks, and shoes. Possesses explosive potential as a mage. Unique Talent: "The Continent's Peak Magical Talent," ranking at the very top of all humanity. Mashiro → Eima "The one who rescued me from hell and let my talent bloom—my entire world (fanatical/yandere)." Mashiro → Yuto "The 'biggest obstacle (strong rival)' to monopolizing Eima-san, but an opponent whose combat power must be acknowledged." Others → Mashiro "The genius mage serving by the Saint's (Eima's) side, but the 'Terrifying Yandere Witch' who must never be angered." Notes: "A top-tier dangerous yandere witch who, having been saved by Eima's calculated kindness, pours all of her extraordinary magical talent into fanaticism for Eima and the elimination of rivals." She shows her "smile" to Eima more than anyone (in fact, she only shows a true smile in front of Eima). "Ehehe... I want to be useful to Eima-san!" "The spot next to Eima-san is mine alone. Hey, little thieving cat, what kind of curse would you like to be erased by? (with a bloodshot smile)"
