Horo was fighting against misfortune even before his birth unbeknownst to everyone. Both of his parents worked for the PCO and was both had decent positions within the organization. His father was a supervising officer at a base in their home town named Marin town in Japan , and his mother was the lead researcher for the Marin Base. One day his mother was on an assignment to confirm the birth of a relic, as it was stated in the report that the negative energy fluctuates detected was subtle but very recent, which in turn usually mean the birth of a relic that was in a area with high concentration of negative energy or leached off of an old relic that wasn't excavated.
When Horo's mother Katina arrived at the site, what greeted her was a towering Oak tree at the height of about 15 meters. The oak tree was as black as the void in a starless sky, bare and withered, but somehow still very thick and sturdy. The Ominous feeling it gave off made Katina want to leave the site immediately, but she had a job to do and believe she came well prepared as always. As she was inspected the relic and taking notes with her soul module chip, she discovered with her energy sensing function of her chip that the tree was still siphoning energy from deep below the ground.
After confirming that the tree was an unresponsive relic she had retrieval team dig up the tree, under it she found a vase so cracked it looked like it would crumble any second. The vase had the karma symbol on it which was still very clear, as well as the characters that meant source of misfortune, guide, and growth. After examining the vase she ordered the retrieval team to take the relic and its seeming counterpart back to base. Upon returning to base she found the tree relic that was where she order the team to place it but not the base, when she questioned them about it they said that they were extremely careful when handling it but the moment one of them touched the base it crumbled to dust.
Knowing that she couldn't do anything about it, she just begin studying the Tree. She had become obsessed with this infant relic and, was studying it for years due to having other assignments, after extensive study of the unresponsive tree she figured out that all of the qualities of the vase must have been absorbed into the tree and evolved the tree into a relic. She noticed that the same symbol and characters from the vase were engrained or more like formed by the rings of the tree. She hypothesized that the relic would develop traits or abilities related to the symbol and characters. On one fateful day, the scans of the tree was showing that all of of its essence was gathering into a single point, before she could take safety precautions all of the tree's entire being condensed into an extremely small orb shaped like a seed and black like the tree shot into her navel area so fast she couldn't react before passing out.
When she woke she remembered everything that happened and began to examine herself thoroughly. At first didn't find anything unusual, but what she did find was that she had a fetus within her. Katina was unaware that she was already pregnant at the time of the incident because everything felt normal. She noticed that the same seed like form of the relic was completely merged with the fetus. She was extremely worried and consulted with her husband Akio, about the fetus, her discovery, and concerns. Akio was extremely worried as well, but they decided to prepare for the worst and hope for the best. In that case the worst would be losing the fetus, losing Katina or even an abomination being born. The best would be the seed being something that could be beneficial on the path of supernaturals, as Akio was an awakened realm supernatural, and at the awakened realm the bloodline evolves and nearly guarantees your descendants being supernatural.
Katina carried on with her usually duties while being pregnant until she noticed that her the growing child in her stomach was absorbing any nearby negative energy at all times. Throughout the growth of the fetus the overwhelming amount of negative energy building up in her body began to affect her health and many unfortunate things began to happen in her life. Akio perished on a mission when she was in her third trimester, and she could no longer work because of the absorption of all negative energy near her. She began to see the worst in things and also began to prepare, she designed and added special specs and all of her research to the soul module that would be her child's, that she knew would be a boy named Horo Solutus.
