My name is Ike, a demon with exceptional magical abilities that enable me to capture a fort single-handedly. My powers are so immense that they leave my enemies in awe, whether they are friends or foes. Despite my formidable strength, there is something that I keep hidden from other demons - I am actually human. By utilizing modern knowledge, I have been able to maintain my secret while being recognized as a great commander and the driving force behind Maou's army.
