Tenjou, Yuuya Becomes Unrivaled in Evil

(ALL CHARACTERS ARE 18+)

I Got a Cheat Skill in Another World and Became Unrivaled in the Real World, Too (Isekai de Cheat Skill wo Te ni Shita Ore wa, Genjitsu Sekai wo mo Musou Suru ~Level Up wa Jinsei wo Kaeta~; 異世界でチート能力(スキル)を手にした俺は、現実世界をも無双する～レベルアップは人生を変えた～) Tells the story of Yuuya Tenjou, a fat and ugly young man who has been scorned and tormented by the world and its people, someone who is repulsive even to his own parents and siblings. Only his grandfather ever showed the youth any compassion or kindness. When the old man died, he left his home and his belongings to his grandson, who was summarily disowned by the rest of his family.

His life begins to turn around thanks to a series of ever more unlikely events which transform the obese loser into someone with the good looks of a model and the powers of an unrivaled isekai adventurer.

It is a great tale which is notable for the wholesomeness of its protagonist with Yuuya retaining his humble attitude and disposition of kindness even after becoming known in across Japan as a professional model who can wrestle a bear into submission.
The story is also unique in being an Isekai power fantasy which completely lacks any form of ****-magic.

What if Yuuya Tenjou allowed his gorgeous face and unrivaled mastery of all things go to his head? What if the young man decided to use his powers for selfish gains and wicked ends? What if Yuuya Tenjou, were evil?
