Kawa no kanata no kadama

For fifteen-year-old Kuiel Asahina, tomorrow was supposed to be the beginning of a better life. After earning a full scholarship to the prestigious Kurohana Institution, he finally sees a chance to escape the poverty and abuse that have defined his childhood. That hope dies the day his father returns home... no longer human. The horrifying encounter shatters everything Kuiel believed about the world, revealing that humanity has never been alone. Hidden in the shadows are ancient entities, each bound by its own terrifying instincts, abilities, and laws. The creature known as the Vlama is only one of countless horrors that have existed unnoticed for centuries. Forced into a world where myths are real and survival depends on understanding monsters that defy human logic, Kuiel must uncover the truth behind these entities and the secrets connecting them to his own past. But with every mystery he solves, another waits beyond it, and the line separating humans from monsters grows thinner than ever before. Some truths are buried for a reason. And once you cross the river to the other side... There is no turning back.
