A bunch of demi-human kids wanted to meet their idol; the Church and the king wanted to demonize the Shield Hero; the World needed a guardian; the fans desire cathartic justice. A definitely-not-the-Devil antimatter dragoness of Creation with work experience is perfect for the role. Poor Fitoria's pride. (Distant Renegade of Zero sequel)

Naofumi had an unexpected encounter.

Tyler Bryant was ordinary Pokémon Trainer (but not too ordinary) until he found himself in a world of the Four Heroes. Join him as he helps the Shield Hero fighting the Waves of Catastrophe that threatens to destroy the world.

being the shield hero meant you had to rely on other to fight for you. but friendship and trust means everything even though they don,t really preach it. after being framed can naofumi rise and better then anyone ever was.
