A brief description of the Konjiki No Moji Tsukai – Yuusha Yonin Ni Makikomareta Unique Cheat manga:
Okamura Hiiro is very withdrawn and obsessed with books. According to him, books are his meaning of life. His story begins with the usual call of heroes. Five men were called. Four of them are friends and are heroes, but Hiiro, a total loser, was drawn by chance. Hiiro decided not to help a country that needs heroes to fight the demon king. Why not? “I don’t believe you. “I’m not friends with them. It’s none of my business, I’m just an ordinary man taking care of his own life. So for now.” And only a few people know that in this ordinary man, Hiiro, there really is a power that can change the world.
