|“||Sorry for the long wait, people of Mikado! Now that Ken Satori, the Peerless Double-shot Sniper, is on the scene...||”|
Ken has messy chin-length light brown hair, parted in the middle so as not to get over his face, and green eyes. He is always seen wearing his Border Uniform.
When he is in trigger mode, like the rest of his unit, he wears black leggings and a red, high collared athletic jacket with the A-rank Border emblem patch on his right shoulder, and a long black stripe going down the middle of each sleeve. Being a Sniper, he usually wears a Bagworm over his clothes.
Ken is a goofy and carefree person, even inside of combat. He is frequently trying to call attention to himself, as shown during the Black Trigger Retrieval and Third Neighbor Attack Arcs. He is very proud of his unequaled ability of being able of using two sniper rifles at the same time, and is frequently boasting it.
