Ken Usato is a normal high-schooler in every sense of the word—average grades, dreams, and a tendency to dislike extraordinary people. However, when he encounters the president and the vice president of the student council, both popular and extraordinary, he immediately befriends them. All of this is interrupted when Ken's new friends are summoned into another world—and he accidentally gets summoned as well! Dejected and with no way to return, he resigns himself to staying quietly in the new world—until he finds out he has an affinity for healing magic, a very rare form of magic which gives him both self-confidence and the attention of all mages. However, not all attention is good, which is something Ken realizes when he is noticed by a crazy fellow healing magic user...

After Mash Burnedead's clash with Magia Lupus, the secret about his powers is now out in the open. The short-lived celebration ends when the Bureau of Magic summons Mash before an audience of Divine Visionaries, who collectively decree Mash should reap the consequences and die. However, an evil shadow organization called Innocent Zero hijacks the inquiry to demand that Mash be kept alive. Mash proves that he is capable of dealing with Innocent Zero, but the Divine Visionaries' verdict remains unchanged. Luckily, Mash finds unexpected allies in Divine Visionary Rayne Ames and Headmaster Wahlberg Baigan, and they successfully defer his execution until Innocent Zero is defeated. Mash is now allowed to live under one condition: he must be selected as the Divine Visionary candidate by the year's end.
