The Invincible-Looking Teacher of Kivotos

When he opened his eyes, the world had changed—but his resolve had not. Twenty years of memories burn crystal clear in his mind as he arrives in Kivotos, the city beneath the halo. This time, it's real. This time, he can see them. This time, he can actually help. But Kivotos is no fairy tale. Beneath the halos lies a world of harsh realities and darker truths. As a teacher who has seen too much, he must navigate a system that tests not just strength, but the very nature of humanity itself.
