Ep 11. What Happened On a Certain Day in the Castle Town

Astro's shoulder is injured during their mission to stop Mars and the Diamond Kingdom's invasion, and the group needs to find a healer as soon as possible. They head to the capital city of the Clover Kingdom and visit a church where Noel's sister, Mimosa, is training to become a priestess. There they meet Sister Theresa, a powerful healer, who takes a liking to Asta and agrees to heal his injury.

While they wait for Asta to recover, the group splits up to explore the city. Yuno goes off on his own, hoping to find out more about the magic knights who are being selected to participate in the upcoming Magic Knights Entrance Exam. Meanwhile, Asta, Noelle, and Mimosa come across a group of kids trying to catch a runaway chicken. Asta offers to help and ends up befriending the children, who show him around the castle town.

During their adventures in the city, Asta and the others witness a mysterious incident involving a young girl and a group of cloaked figures. They don't think much of it at first, but as they continue to explore, they realize that something strange is going on in the city. They hear rumors of a shadowy organization called the Eye of the Midnight Sun, and begin to suspect that they may be behind the strange occurrences.

As they investigate further, Asta and the others find themselves caught up in a dangerous game of cat and mouse with the Eye of the Midnight Sun. They are forced to use all of their skills and abilities to stay one step ahead of the mysterious organization, while also trying to find a way to put a stop to their nefarious plans.

As the day wears on, Asta and the others find themselves drawn deeper into the conspiracy surrounding the Eye of the Midnight Sun. They uncover shocking secrets about the organization's origins and goals, and realize that they may be the only ones who can stop them before it's too late.

In the end, Asta and the others are able to unravel the mystery surrounding the Eye of the Midnight Sun and foil their plans. They return to the church with a newfound respect for the power of magic, and a renewed determination to become the strongest magic knights in the Clover Kingdom.
