The story of a child in the Underworld who became a demon overnight.

Aimé was born in the Underworld of Belobog, on Jarilo-VI, but for unknown reasons his birth parents abandoned him (and his twin brother) in the Great Mine, in a crate of Geomarrow. He was discovered by two thieves - Anya and an unknown male. Anya, who was a kind woman, could not turn away from an abandoned baby and chose to take him back to the thieves' hideout, despite warnings of their leader disapproving of her actions. As expected, Alain wasn't happy to see Aimé, and claimed he would be a waste of resources and keep the rest of the group awake with his crying. Anya argued that there was absolutely no way she would leave him, and that she would take full responsibility of Aimé until he was older. Alain relented, but with the threat that if Aimé became more trouble than he was worth, him and Anya would both be thrown out.

From then on, he was raised and cared for by Anya, but some of the more kindhearted members of the thieves' group would also look after the boy. Anya named him Aimé - meaning beloved in a foreign language. She taught him everything that she knew, how to read and write, basic math, languages, anything that could be of use to him in the future. As Anya was one of the younger members of the thieves' group, she didn't go on as many runs as the others did, and would instead spend time looking after Aimé and taking him to the playground outside the orphanage.

Unfortunately, Anya's attempts to raise Aimé into a kind person were continuously trampled on by Alain. He saw Aimé as weak and treated him rather poorly, telling him that if he doesn't grow a thicker skin, he'd be as good as dead. Attempts to take Aimé on crime runs often ended in failure, and despite Anya demanding Alain to leave Aimé out of it, the man was only more convinced Aimé was a mistake.

At some point, Aimé was able to make a little money by helping out an elderly woman in town. He brought it back to Alain, thinking he'd be able to convince the older man that he could prove his worth by helping others, but Alain simply laughed in his face, telling him what he made wouldn't even last a day. Alain told Aimé that things like kindness and community would only bring his downfall, that he'll never survive in this world if he remains weak. Sensing Aimé's hesitance, Alain threatened to feed him to the Fragmentum Monsters that wandered past the tents at night. Terrified, Aimé begged him not to, promising to be better.

Aimé went on to adopt a similar personality to Alain, outwardly kind and friendly, but secretly plotting against those he assisted. He would offer a hand to the miners while listening in on their conversation, then relay it to Alain who would organize another crime run. This proved successful, and the thieves were able to steal more resources than ever. For the very first time, Alain praised Aimé. However, this happiness would not last, as Wildfire had caught the thieves. Anya had enough time to tell Aimé to run and hide, and to not come out until it was absolutely silent. Aimé hid away, trying to block out the sounds of running and yelling, fighting and things crashing to the ground, until - silence.

When he left his hiding spot, the thieves were all gone.

Left with no guidance or family to call his own, Aimé continued to live in Rivet Town despite the monsters that roamed the area. He learned how to sneak past or distract them by throwing stones in another direction, but that didn't mean there weren't close calls. A few times he was saved by a member of Wildfire, but he would run away before they could ask him anything. He would offer help to Underworlders in Boulder Town in exchange for food or other necessities, but always turned down offers for him to stay with them or rest in their homes.

Aimé was no longer the cheerful or hopeful young boy he once was, fully believing that surviving meant caring for only yourself - that everyone else are pieces to use and discard once you're ahead. Following in the footsteps of Alain, he put up walls and only feigned kindness when he wanted something from others, having no desire of forming bonds, thinking it was the best for everyone if he kept away.

However one night when he visited the playground at the orphanage, he found he wasn't alone. He came face to face with an unfamiliar man who greeted him kindly, and didn't flinch when Aimé responded harshly. His tone remained gentle, and he told Aimé that their meeting was fated to happen. Aimé might've claimed to have no interest in forming bonds or growing close to others, but he was still a child deep down inside. Maybe that's why he took the man's hand.
