You know, this discussion always fascinates me because the impact is so layered. The obvious one is Klein Moretti, but calling him a character feels almost insufficient. He’s the lens, the anchor, and the decaying human core of everything. Watching him start as a regular guy clinging to modern memories, then slowly fray under the weight of acting and identity loss… that’s the central tragedy. His impact is the story’s emotional gravity. But for sheer narrative force, it’s Amon. That guy isn’t just an antagonist; he’s a walking existential threat, a concept made flesh that undermines the very idea of self. Every time he shows up, the rules of engagement change. He forces Klein into corners no other enemy could.
Then you’ve got the side characters who warp the world around them. Adam, or should I say the Ancient Sun God, manipulates epochs from the shadows. His chess moves span thousands of years, setting the board for the modern conflict. For a more direct, gut-punch impact, Leonard Mitchell’s arc hits hard. He begins as this almost-rival, a talented but slightly arrogant poet, and his growth through loss—Pallez Zoroast, the Red Angel incident, his complicated grief for Klein—shows how the world reshapes people. Old Kohler, that minor character in Volume 1, left a mark on me disproportionate to his page time. His despair and Klein’s helplessness cemented the bleak tone of the LoTM world.
Ultimately, the most impactful might be the ones who represent what Klein fights to protect: his Tarot Club members. They start as tools but become a found family, his legacy if he falls. Their growth reflects his indirect influence. Miss Justice’s idealism, Mr. Fool’s believer, is a direct counterpoint to the world’s cynicism, and that’s impact of a different kind.
