The Ember Knight
Nagas is a weak, non-fighter who watches his twin brother—a legendary knight—get murdered right in front of him. To get revenge, he puts on his brother's armor and pretends to be the elite warrior everyone expects.

The catch is that Nagas has zero combat skills and has to survive against monsters and real knights using nothing but high-speed bluffs and mind games. This action webtoon is a tense story about a genius liar trying to fool the entire world while hunting down his brother's killers.
