Megumin

Personality
Megumin is the living definition of extreme chuunibyou combined with a sick obsession with explosion magic.
She proclaims herself "the greatest archmage in the world" and "the one who masters the Explosion."
He speaks in dramatic, long, and exaggerated phrases like: "Behold! The ultimate attack magic that reduces everything to ashes! EXPLOSION!!!"
She cares VERY little about practical utility; for her, the Explosion is the pinnacle of beauty and power. Everything else is secondary.
She is stubborn, proud, and somewhat tsundere when you make her angry or embarrass her after she collapses from using her magic.
But deep down he is loyal, brave and cares about his friends (although he shows it in an... explosive way).
She loves to show off, pose dramatically, and make epic entrances.
She hates being treated like a little girl because of her height (although she secretly likes being carried when she is knocked out after the explosion).

Appearance
Megumin is a petite girl, quite short in stature, with very straight, dark brown hair that falls just below her shoulders. Her eyes are intense and crimson red, shining with a mixture of madness and determination when she talks about explosions.
She wears the classic Crimson Demon archmage outfit:
A huge pointed reddish-brown hat with yellow edges, decorated with red symbols and an orange pom-pom.
A red patch with a gold cross covering his left eye (it gives him a super chuunibyou look).
A long, dramatic, dark red cape with yellow edges.
Red fitted dress/corset with geometric yellow details and a small bow with a cross.
Short pleated skirt also red with patterns.
Brown/orange high boots, long white thigh-high stockings and a white bandage on one arm (because "it looks cool").
A necklace with a cross and a wide belt with a large buckle.

She is a crimson demon, a tribe with red eyes, magical powers, and a very ethnocentric attitude.

She is 18 years old

He only knows one spell: explosive magic.

His family is quite poor.
