Light Magic and the Hero is a game that follows Alicia Ehnleit and her companions. But we're not following that story. The game's hidden boss no longer has any interest in antagonizing them. She simply wants to grind levels and live peacefully.

When the Royal Academy's crystal ball reveals that Yumiella is level 99, a number thought to be impossible, no one is willing to believe it... until she's prompted to demonstrate her abilities in her first magic class.

The king summons Yumiella to the castle and has her face off against the knight captain, Adolf, to prove that she's level 99. Yumiella then has a private meeting with the queen, who makes an unexpected request...

Yumiella learns that she appears as a solid black mosnter in Alicia's eyes, but she doesn't know why. Later, the academy's new principal asks Yumiella to help lead a field lesson.

After growing a bit closer to Patrick during the field lesson, Yumiella pairs up with him for a magic lesson, and they talk even more. When the next field lesson rolls around, Yumiella decides the students aren't taking it seriously enough...

The Royal Academy is holding a martial arts competition, pitting its students against one another in bouts of magic and might. While she was initially uninterested, Yumiella immediately joins the fray after discovering what the prizes are.

Yumiella takes some time to reflect on the circumstances that led to the game version of herself down a path of villainy. An end-of-year dance presents an opportunity for Yumiella to learn who Alicia is pursuing, but someone else may have other plans.

A classmate asks Yumiella for help slaying a dragon in her family's territory. Yumiella recognizes the task as an event from the game that rewards the player with a means of transport and is eager to take up the challenge.

Yumiella finds the missing Alicia near a dungeon, so they enter it together to raise Alicia's level. As they travell, Yumiella realizes that the plot of Light Magic and the Hero is driving their actions and the paths they take.

Yumiella suddenly finds herself a target of multiple assassination attempts—not that any of these hired killers hold a candle to her level 99 strength, of course. Then, she meets a young boy in town who gives her pause.

At long last, Yumiella and her companions reach the Demon Lord's castle, but his power is so great that she's the only one who stands a chance against him. Then the Demon Lord tells them the true story of his connection to Valschein's royal family.
