(Haha) Well, there is no choice since the main story is about the princess being abducted (slowly living) in the Demon Lord Castle but I hope that one day the princess will remember his name... 【Haritoge Majiro by Koyama Rikiya】 I am actually quite young! I have a tough body, you see, even my limbs look so sturdy and I am quite good at fighting. I even have a lot of experience and wisdom in life, I have also experienced various ups and down... Don't I look like that!? In fact, I am young! I'm still brimming with youthful enthusiasm! So let's do it! (C)Kumanomata Kagiji・Shogakukan/ Maou-jou Suimin Sokushin Production Committee
