Jouhai Shougun, Mata Yabureru

Tina, the young daughter of the world's strongest knights, the Vathermunt Chivalric Order, is to fight for the kingdom of Heiminar in her very first battle. Here, she comes across the infamous legendary mercenary Doh Durcus. Although he may have fought opposite her own father and brother in the past, surely there is something she can learn from fighting alongside him - but is there anything worth learning from someone who has lost every battle he's fought?
