Laonen's Dysmagia Syndrome!

Shaken by his encounter with Orsis, Alba suddenly collapses from a seizure. In this world, humans are born with magical power. However, Alba suffers from “Laonen’s Dysmagia Syndrome,” which prevents him from controlling the release of his own magic. When he regains consciousness, he feels truly welcomed as family as his stepfather, Hals, and Orsis offer him warm words.
