Hell Mode (Manga): Volume 4

Allen and Cecil continue their escape from Carnel and his goons. In the process, however, they run into the same murdergalsh Allen fought years ago, turning their situation from bad to worse! Stuck between a rock and a hard place, Allen makes his choice: he'll defeat the murdergalsh so that he and Cecil can head home.

But other questions plague Allen's mind. What exactly is a "noble duty"? Why must every noble with a Talent be conscripted into the army? Gradually, he finds himself learning the truth of the world he was reincarnated into.
