Forgot who Richard was, but I fear asfhoiasfjoiasfjpi may be right and the captor may be trying to frame Dias. Aruna was wise to increase the bribe from possible enemies.
People need to notice Dias's Armor of God! Dude makes 100x the size of his force retreat simply from his good reputation and good relationships by being a good dude. Simply being virtuous turned his plight from an impossible suicide mission into a strenuous, but feasible exercise. The biggest threat to them was a snake one missed but the other warned of.
Good stuff. I love this manga.
