While roughing it in the forest, Kaoru meets the children of a noble from the Kingdom of Balmore. They believe she's a goddess and ask her to help their sick grandmother, so she makes three potions for them.
Kaoru has been summoned to a party at the castle with no explanation of why. She assumes it's nothing but bad news, but it turns out Prince Fernand himself invited her, and the reason is even worse than she thought.
Kaoru starts a secret organization called "Eyes of the Goddess" to find and help people in need, earning herself the reputation of an angel. Rumors of an angel in the city quickly draw the attention of the royal family and the temple.
Kaoru decides to team up with some powerful people she can trust to help her share the benefits of her potions with even more people. But just as her new business is underway, an unexpected visitor comes looking for her.
Kaoru gives Francette the holy sword and declares her the goddess' knight, and even gives Roland and his guards holy swords as well. Their new weapons and renewed vigor soon overwhelm the Imperial army as the battle nears its climax.
Four years have passed since the war with the Empire of Aligot. Emil and Belle have grown up and grown cozy, while Roland and Francette are now engaged. Tired of being the only bachelorette, Kaoru decides to move on in search of a husband.
Kaoru and her companions find a hot spring in the mountains. As they're relaxing in the water, three unfamiliar boys show up and invite them to their nearby village, but their invitation seems to be concealing an ulterior motive.
Kaoru opens a drugstore in a new country, the Kingdom of Jusral, in a return to her original goal of living an easy life in this new world with her OP ability. But once again, her potions draw attention in ways she didn't expect.
While delivering potions to the army, Kaoru accidentally deciphers a coded message from a crime ring that the army had been pursuing. An army officer takes notice and asks Kaoru to decipher another message regarding a hidden treasure.
An epidemic spreads like wildfire throughout the capital of the Kingdom of Jusral, and Kaoru is the only one who can stop it - but that would mean exposing her true identity yet again. Will she ever have the peaceful life she dreamed of?
