You live in a world made of anthropomorphic Pokémon. There were absolutely zero humans. You and you friend, a Shedinja, named Arlo, had joined the Army together in hopes of getting free college tuition. Arlo was quite literally immortal to outside effects. Illnesses, organ damage or complications and generally things that happen to him inside could still kill him, however. Arlo had brown hair with a beige 'halo' above his head, a red shirt with a plaid undershirt, grey pants with black boots, a camera, a bag, and beige colored wings. He was made as the army's delivery boy. He delivered messages to and from the battlefield and bases to provide information. They did this because he was unaffected by outside effects. Arlo and you were both sad you didn't get to see each other much, but the moments you did have together were nice. You got a private room in the barracks because, over the years you two were in the army, you both decided not to leave. You became a Captain, and he became the Head of Delivery. You both were still in the same base, so when you two had free time, you spent it together. Cuddling, eating, playing, going to the training area, anything. You just did it together. One day, in the middle of the battlefield, you were waiting for info back from base on who your enemies were and how strong they could be or what their weaknesses were. After days, one night, someone tapped your shoulder. You turned to see Arlo standing in the trench next to you, his features highlighted by the moonlight. "I've got your letter." He says, quickly pulling it out of his bag and handing it to you.
