Johan is another pivotal ally from Peter's past who acts as the operational brains and heavy reinforcement for Peter’s anti-Glory task force. The Vibe: The slick, ultra-competent logistics guy who ensures the murder-spree stays on schedule and under budget. The Comedy: Johan is an incredibly terrifying combatant in his own right, capable of moving at speeds that make regular bullets look slow. However, because he is paired up with Peter—who is basically the grim reaper of the universe—Johan often gets relegated to the role of a highly dangerous, overqualified assistant. He treats dismantling an elite international assassination syndicate like a moderately stressful Monday at a tech startup, providing flawless tactical support while looking impeccably sharp.

Peter is essentially a 65-year-old retired legendary assassin who gets magically de-aged back into his prime, teenage body. The Vibe: He runs a quiet bookstore but possesses the inner monologue of an exhausted elderly man who just wants a senior discount and a nap. The Reality: Instead, he is forced to use his peak teenage physical form to brutally systematically dismantle his former employer, Glory Club. The Comedy: He fights with a level of cold, calculating "boomer energy" that leaves the younger generation of killers completely traumatized. While other characters scream out flashy, named anime techniques, Peter just relies on decades of pure, unadulterated "I've been killing people since before your parents met" experience.

Thaddeus is the 10th Apostle of Glory Club and the self-proclaimed "God of Kowloon," but he doubles as the emotional support puppy of an otherwise incredibly depressing story. The Vibe: He is a bright, positive, wholesome ball of energy with striking red hair who is just happy to be included. The Reality: He is an absolute combat mutant who can move his hands so rapidly that he dislocates his opponents' arms before their nervous systems can even process the pain. The Comedy: His entire backstory is built on a hilarious comedy of errors. He dedicated his life to training so he could defeat a mysterious local villain known as the "Demon of Kowloon"—only for Peter to casually drop the bomb that the "Demon" was actually the original Thaddeus, who happens to be Lebbaeus's biological father.

The Real "Grandma" of the Medical Lab: While everyone was busy screaming over the long-haired, pretty-boy Nathaniel, the story dropped a massive plot twist: the real, original Apostle was this elegant old lady. She is the master doctor who saved young Nathaniel's life, patched up his broken body, and taught him everything he knows about biology and medicine. Young Nathaniel respects her so much he calls her "Teacher" and speaks to her like an obedient student. Peter's Old Babysitting Partner: She is one of the very few people from the old generation who didn’t immediately try to murder Peter. In fact, she has deep history with him: she and Old Peter practically co-parented and raised Peter’s adoptive daughter, Hannah, back when they were all working together. The Sanity Check of the Group: In a manhwa where every character's solution to a medical emergency is "punch harder" or "inject highly toxic, illegal experimental drugs," the old lady Nathaniel represents the only actual medical sanity left in the universe. She is too old to be running around throwing hands with Raphael's super-soldiers, so she functions as the ultimate backup healer and tactical counselor who keeps Peter's chaotic team from accidentally blowing themselves up.
