Megumin

Megumin (めぐみん, Megumin) is one of the secondary characters of Isekai Quartet. Coming from the world of KonoSuba, she is well known for her love of explosion magic.

Appearance
Megumin is a rather short and thin girl, with shoulder-length brown ponytails, light complexion, and crimson-colored pupils. She dons a massive brown wizard hat with a face on it, fingerless black gloves, and a choker on her neck.

She wears a brown coat, red short skirt, with a brown belt on her midriff. Also, she wears calf-length light brown boots, with a knee-high bandage wrap on her left leg, and a black stocking on her right leg.

Personality
Megumin's most defining trait is her love of Explosion Magic, often boasting on it's offensive capabilities and how it is considered the greatest offensive magic in the KonoSuba world. Otherwise, she is quite hyper active and will often lose her self-control. When someone slights or challenges her, she can become aggressive, as seen when Vooren Grantz doesn't consider her song to be a song to start off the day. She also shows chunnibyou tendencies, as noted by Tanya von Degurechaff. Despite all of this however, she is intelligent, something natural of the Crimson Demon Clan.

Plot
She is the one who pushes the button that brings her, Kazuma and the others to the world of Isekai Quartet.

During the talent show, she uses her explosion magic.

Explosion Magic
While it is only Megumin's sole ability, it's considered to be the most powerful offensive magic in KonoSuba. As per namesake, the spell creates a destructive nuclear-like explosion. However, it has a long casting time and it takes alot of mana, so much so that Megumin can only use it once per day. This ability can also be combined with Ainz Oown Gown's Nuclear Blast, to make the said magic more potent.

Intelligence
Due to her being part of the Crimson Demon Clan, she's intelligent. This was seen on Season 2 Episode 12, where she is able to memorize the script she mostly made herself.

Satou Kazuma
She sees him as someone who might hold back the team on Field Day and sometimes insults him now and then. Being one of the people that drives him crazy. Though she does respect and care for him, trying to help him and Aqua from detention and even defends him by stating Kazuma won't cheat. Also giving him chocolate.

Yunyun
Like in the KonoSuba universe, she often bullies her, despite Yunyun's innocent and lonely nature. They are also both part of the Crimson Demon Clan, a clan in KonoSuba.

Ainz Ooal Gown
She has a decent relationship with Ainz, the two working together a bit when helping their friends out of detention. They also did well in making a combo move during dodgeball, though Ainz was forced to chant with her reluctantly. She then sees him as a rival when hearing from his 'son' that he has the same tastes as her, much to his confusion.

Albedo
Due to Albedo's unconditional love for Ainz, she is seen to hate Megumin, as they have a decent relationship and both of them have the same preferences.

Pandora's Actor
He and Megumin hit it off with the two having the same tastes. Pandora himself also commenting his father having the same tastes as her much to Megumin's delight.

Vooren Grantz
While not much of their relationship is explored, they are seen fighting over the intercom, on which music to play for the morning.

During the "Test of Courage" activity, Megumin spoke up to him when he tried to assert leadership of the team that also consisted of Beatrice and Mare (whom they were surprised at learning that it was a boy), "Hey! Stop trying to boss everyone around, or have you forgotten that it's my job!"

One day, Megumin learned that her fellow party members, Grantz and his squad mates were caught in attempt to steal from the principal. After she and Darkness were horrified in finding something in Aqua and Kazuma, the pair saw Grantz and his squad mates were behaving in a weird manner different from Aqua and Kazuma. Megumin (with the help of "Visha" and Weiss during science class) assisted Subaru and Emilia in getting the five out of the horrifying detention. When Grantz thanked her, she said, "No sweat. But, you should be thanking your commander, instead.  I mean, she could've stopped us, but she didn't."

One day, Megumin and Grantz selected "ketchup" in the survey of what they liked in their chicken wings. She claimed to him, "I'm a Crimson Demon. So naturally, I choose the crimson sauce."

Subaru Natsuki
When Kazuma was staring at the boy in the back row, Megumin's first remark was, "He's wearing the same stupid-looking outfit you used to wear."

During the class discussion about the field trip, Megumin threw a jabbing question on Subaru when he was supporting Kazuma's proposal of "Test of Courage", "So, are you crazy? Or just stupid?"

One day after Megumin and Darkness saw the horrible effects of one detention session that Kazuma, Aqua, Grantz and two of his squad mates being subjected to; the pair sought Subaru and Emilia for help. During science class, Megumin and Subaru (with the help of "Visha" and Weiss) got their plan together. After she using Explosion magic, Subaru gave her a piggy-back ride.

Trivia

 * Megumin shares her English voice actress, Erica Mendez, with Puck and Raphtalia.
