Suterareta Yuusha no Eiyuutan - Story 2-3:『Begin Preparations』

SSR-ranked killer Mu Hui died in an explosion, only waking up to find herself transmigrated into the body of a vicious female supporting character in a book.

Hao Ren (literally means “good man”), as his Chinese name suggested, is a good man, and his ideal was to live a restful, comfortable life as a landlord. At least that was his plan before a couple of abnormal creatures rented his house.

She had a dream: the world was brimming with light. Family. School. Friends. Trains. Buses. Movies. Books. In that world of light, she grew into adulthood… and at the very end, in a white room, she fell into darkness. She awoke from the dream to find that she had become a demon. In the demon world, she lived a carefree life until she encountered a powerful being.

Jiang Chao Ge, people called him “money hungry Jiang”. Went from a street hooligan to a newly appointed city official. The difficulties he experienced along the way he hid deep inside himself and did not say a word about it. He only wants be blinding in the eyes of everyone from now on.

Who would’ve thought that before he even had the chance to enjoy the wealth and reputation, he inexplicably passed into a different world. Moreover to his bad luck, the first thing he was faced with was being chased down to be killed. He just casually took a worn out rusted old sword to defend himself, why are these country bumpkins who’ve never seen the world chasing him so relentlessly?

In order to get himself a body guard, he tried to summon the ‘animal spirit’ in the sword. In the end, he summoned a devilish brat who rolled his eyes upon seeing someone, who only called him a good for nothing, who bit him whenever he got close. Where was the powerful, first class spirit weapon he was promised?!

No money, no power, no people, life constantly at risk. He couldn’t see the path ahead, nor could he face the fierce tiger behind. Jiang Chao Ge was beaten back into the abyss with one hit. In this unfamiliar world full of thorns, there is only one reason that allowed him to persevere and that is: to go back.

Hence, he was forced to embark on a desperate and risky journey with this devilish brat who he loathed mutually.
