Tomohiro Yasu

Yasu Tomohiro is one of the otherworldly heroes summoned by Goddess Vicius to fight against the Great Demon Emperor. Once a victim of bullying, he became arrogant and petty after being chosen as an A-Class Hero, eventually forming and leading his own group. However, following the events of the Anti-Demon White Castle Battle and the War against The Country at the End of the World, Yasu regained his humility and chose to live as a wanderer.
