Konosuba: Megumin

She's one of the three protagonists, also known as an Arch Wizard of the Crimson Magic Clan in the Fantasy World, she is straightforward, who can speak in an old-style Japanese dialect. She can be very hyper and lively at times and has chuunibyou tendencies (much like Rikka from Love, Chunibyo and Other Delusions) like the rest of the Crimson Demon villagers. Despite her intelligence, she had little to no self-control like her ridiculous Explosive magic, since she can only use one Explosion per day before collapsing, she ends up wasting her magic on destroying random locations and fortresses for no reason. She has a calm and cheerful personality, but she can easily become aggressive when she feels slighted or challenged like her time with Yunyun.
