Chronicles of the Hidden World: How I Became a Doctor for the Gods, Vol. 1 (light novel) (Chronicles of the Hidden World: How I Became a Doctor for the Gods (light novel), 1)

A JAPANESE FANTASY OF GODS AND CURSES... After dying in our world, Yae is reborn into a strange country called Izumo, which resembles ancient Japan, except for the fact that the supernatural is commonplace. When she is attacked by a terrifying monster called a shade, Yae has no choice but to release Arai, a golden tiger and former god, from his seal. In no time, the bossy tiger has her helping to find his brother, Sui, but it turns out that Sui has fallen ill and will soon become a monster himself. Arai, however, thinks Yae is just the person to heal his afflicted sibling... Does Yae really have what it takes to be doctor to a god? In a world where one's name determines their essence, Yae reincarnates into Arai, an ex-god in the form of a golden tiger, but soon Arai manipulates Yae into assisting his little brother, who suffers from a disease that strips people of their essences
