The idea of being transported to an entirely new world is frightening. Entirely new laws, races, and customs need to be learned, and there’s usually a demon lord that needs to be killed too. This genre of anime is called isekai.
Isekai protagonists often find the idea of living in a fantasy land an ideal form of escapism from the underwhelming life they lived on Earth. That said, they need to get their bearings and the best way to do so is to find a capable ally. Fortunately, isekai worlds are filled to the brim with fantastically strong and wonderfully personable characters.

4 Megumin Is The Strongest Glass Cannon That Satou Kazuma Could Ask For (KonoSuba)
Allocating skill points to a variety of attributes allows most mages to be versatile in any situation. But, Megumin from KonoSuba isn't like most mages. Her endless fascination with explosion magic influenced her to put all her points into that one path, making her the strongest user of explosion magic in KonoSuba.
The one and only fatal downside to that is that Megumin can only use one explosion attack per day before becoming incapacitated from fatigue. She’s the ultimate glass cannon, but one that Satou Kazuma is glad to have on his side.
