Le·ah
/lee·uh/

Leah Pendragon, referred to as Leah, is the protagonist of A Manual to Isekai. She used to be a former businessman before being ran over by a speeding truck out of nowhere. 

Leah has a round face with notable childish features and white skin. Her eyes are large and angled upwards, with an adorable and lively look about them. She also has a long wavy red hair that matches her true eye color.

Leah, as you would expect, behaves perfectly according to her appearance, naïve and a bit too ignorant at times. Interestingly, she still retains a degree of self-awareness, likely due to the influence of her past life. But in the first place, what brought about the sudden change in her cognition is a mystery of its own. Of course, the person herself doesn't seem to be aware about this.

World
/wərld/

The term world does not actually refer to the planet, but to a particular environment, much like its real-world definition.

Reason's Transcendence, typically predated by an elevation in mortal wisdom as the catalyst, is the crystallization of a powerful phenomena derived from an accumulated history of a respective civilization, serving as a hallmark for their continual evolution.
