KonoSuba: An Explosion on This Wonderful World! episode 1: Megumin enrolls in the Red Prison
KonoSuba: An Explosion on This Wonderful World! episode 1, titled The Crimson-Eyed Wizards, opened with a young Megumin witnessing a red-haired, voluptuous mage defeating a monster using "explosion" magic. Upon seeing the effects of the spell, Megumin wished to become just like the mage and asked her advice on the same. However, the mage asked Megumin not to pursue explosion magic as it was the most powerful kind of magic there was.
At present, Megumin and her sister Komekko headed back to their home after catching crawfish when Megumin spotted Yunyun and gave her one, thinking that she was hungry. Upon reaching their home, they learned that their parents had made a good sale that day, due to which they had enough money for a good meal and Megumin's new academy uniform.
While the identity of the customer wasn't revealed, it seemed like she was a seasoned adventurer, who as per her words, was searching for someone. After wearing her new uniform, Megumin blurted out her dream of becoming a great mage of explosion magic. However, her dream happened to shock her entire family.
The viewers were then shown Megumin and her classmate's induction ceremony to their academy, The Red Prison. After the ceremony, the anime introduced us to some of Megumin's classmates, such as a chunibyo named Arue, Dodonka, and Funifura. After Megumin declared her intention to become a lone wolf, Yunyun, who was also in her class, declared her intention to defeat Megumin, whom she thought of as her rival.
After a month passed, Megumin expressed her interest towards explosion magic in front of the class, however, the teacher disregarded it as joke magic with limited usage. Later, the girls were seen in their combat training class, where each of them was to pair up with a classmate and come up with a cool way to declare themselves to their opponent.
As Yunyun was left alone, she had to pair up with the teacher, however, she struggled. Upon seeing this, Megumin came up with an excuse to not train, and allow Yunyun to partner up with Arue. Soon, it started to rain, causing the headmaster's tulips to cause havoc. Once the rain stopped, so did the tulips, making both Megumin and Yunyun realize that they could have avoided the situation if they knew spells.
Later, Megumin was seen contemplating her decision to pursue explosion magic, given that no one except Yunyun supported it. However, Megumin was adamant to pursue it as it wasn't a useless spell, as she saw the mage use it to defeat a giant monster. Thus, she reaffirmed her dream of mastering explosion magic like that mage.
