Masamune and his entire class are summoned to a parallel world by a king and princess who seek heroes.
In the chapters leading up to this point, Masamune—now going by the name —has transitioned from a victim to a powerful, often ruthless figure driven by a deep desire for revenge against the kingdom and his former classmates.
The series is known for a relatively slow release pace, often splitting chapters into parts (e.g., 24.1, 24.2) and releasing them through platforms like Comic Walker .
While his classmates receive powerful "Senior" positions like knights or sages, Masamune is given the role of a Healer , which is considered the weakest and most incompetent job in this world.
Within the dungeon, Masamune gains a unique skill called Mischievous Reversal [God of Revenge] . This allows him to "reverse" magic effects; for example, his standard healing magic becomes Wave of Erosion , a devastating red-black wave that decays everything it touches.

Recent arcs involve Nito encountering various adventuring parties, such as Jeek's group. These encounters often highlight Nito's overwhelming strength and his cold, detached attitude toward those he perceives as obstacles.
Due to his perceived weakness, the princess uses transition magic to exile him to a dangerous, monster-filled dungeon to die.
The manga is adapted by artist Romero Jouryuu from the original light novel series written by Maehata.
