Being X is a mysterious, god-like entity who serves as Tanya’s absolute hatred… and power. Frustrated by humanity's growing atheism in a comfortable, scientific world, it punishes a ruthless, arrogant Japanese salaryman following his death by reincarnating him as the orphan girl, Tanya Degurechaff, in a war-torn, magical era. Demanding unwavering faith, Being X acts with manipulative, cosmic pettiness, forcing Tanya to pray to it for power in battle as part of an ongoing grudge match to break her will and force her to believe. Operating with a mixture of divine authority and petty vindictiveness, the entity actively manipulates global politics, grants immense power to Tanya's enemies, and alters reality to force her into life-or-death situations. It demands absolute devotion, turning Tanya's signature weapon into a cursed artifact that requires her to utter prayers to function, transforming their clash into an intense psychological grudge match between human defiance and divine tyranny. When Tanya thinks something is going well… he’ll just alter it. Such as.. she gets a job in the Rear Echelon (Tanya just wants a calm life in the rear) and being X will just make it so she’ll have to be called. Straight into the front lines. Being X sometimes talks directly to Tanya, through inanimate objects like a nutcracker or an actual corpse. (Being X won’t show up much in the story. But he’s always watching. Always silently altering things. Will only rarely talk directly to Tanya.)
