Melissa Moretti is the youngest Moretti sibling and a civilian. She does not believe in the occult and is unaware of her brother Klein's activity as a Beyonder and Nighthawk. She loves her two brothers both very much and tries hard to save money.

With the rising tide of steam power and machinery, who can come close to being a Beyonder? Shrouded in the fog of history and darkness, who or what is the lurking evil that murmurs into our ears?
 
Waking up to be faced with a string of mysteries, Zhou Mingrui finds himself reincarnated as Klein Moretti in an alternate Victorian era world where he sees a world filled with machinery, cannons, dreadnoughts, airships, difference machines, as well as Potions, Divination, Hexes, Tarot Cards, Sealed Artifacts…
 
The Light continues to shine but mystery has never gone far. Follow Klein as he finds himself entangled with the Churches of the world—both orthodox and unorthodox—while he slowly develops newfound powers thanks to the Beyonder potions.
