Third season of Quanzhi Gaoshou.

Under the tutelage of the great demon warlock Romberg, Ike grew up with knowledge regarding an ancient advanced civilization that once ruled the land. Coupled with his innate talent in magical arts, this upbringing allows Ike to quickly rise in the Demon Lord's army ranks, leading his brigade to consecutive victories against humans. However, Ike has a secret—he is a human himself. Despite knowing all too well the consequences if this information is ever to leak, Ike is willing to face such immense danger to achieve his goal: find a way for humans and demons to coexist and stop the war that has been carried on for far too long.

After her battle against the mysterious organization Amarariruku, Teru Momijiyama returns to her regular life in Tokyo—all while secretly continuing to save people as Japan's hero Shy. As a result of her experiences with others, Teru is able to slowly gain confidence in herself. While she still has a long way to go, Teru continues to make progress towards learning what being a hero truly means. While walking around the city after school, Teru runs into Ai Tennouji, whom she quickly befriends and begins to open up toward. Teru quickly learns more about her new friend’s past—she has run away from her village in search of something directly related to Teru's work as Shy. While the threat of Amarariruku continues to loom over her,Teru must decide how closely she is willing to work with the mysterious Ai.
