Bio: Kei's earlies memory is from when he was around four years old. It was stormy night when he and his older brother, Shiro, were interned in to the orphanage after their family had died. Shiro promised that no matter what happened, they will stay together, and that he would take care of Kei. Over the years, the brothers stayed at the orphanage. Even though people often tried to adopt Shiro, who was considered a prodigy and excelled at everything he did, he would always refuse to go with anyone that separated him from Kei. By the time Shiro came of age and had to leave the orphanage, he had already acquired a well paying job at Saber, and asked for Kei to be released from the orphanage in his custody. The brother were able to life happily by themselves for a couple of years.
Kei always wondered what his brother job at Saber was. Since Shiro was regarded as a genius, Kei always imagined his brother working a researcher for the international corporation, however, he could never explained why Shiro sometimes arrived home completely exhausted. Unbeknownst to Kei, Shiro was acting as the primary candidate and tester for the Intercept X Attacker, IXA, Prototype System, that was being developed by the Saber branch to which Shiro worked for.
One day, during a school field-trip, Kei class was caught in the middle of a Grongi rampage. When Shiro heard the news about Kei being in danger, he took the IXA System without permission and ran off the save his brother. Kei was backed against a wall when his brother arrived to save him, leaving the young man in shock at realizing what his brother actual job was. Kei watched in awe as Shiro engaged three Grongi at the same time. Amazement turned into horror when the last remaining monster attacked Shiro from behind. The Grongi continued its assault until the IXA System shut down and Shiro was left a bloodied mess. As the monster got distracted by the police, Kei rushed to his brother side, just to realize that the wounds on his body were too severe and there was nothing they could do. Before passing, Shiro apologizing having to leave his little brother behind and gave Kei the IXA System. For the first time since he could remember, Kei was left completely alone in the entire world now that the one pillar that had always supported him fell right before his eyes. As anger and hatred cruised through his body, Kei stood up and, with tears running down his cheeks, transformed into Ixa and defeated the last Grongi.
With the death of his brother, Kei, the once happy and carefree boy, was left with a deep-seated hatred for all kaijin, so he uses the IXA Prototype, despite of the sever toll it takes on his body, to hunt down all the monsters he can. After the incident, Saber tried to recover the IXA System, however its GPS was damaged during the fight, which prevented them from locating. At that point Dorian Saber decided that, since the IXA System was being developed around Shiro's physical characteristics, of which he shared many with his brother, leaving Kei as Ixa for the time being was the right thing to do. Kei holds no allegiance to Saber, however, he is in communication with them as the communicator in the IXA System survived the incident. Once in a while, a woman named Ebony requests him to intercept a kaijin, assignments that Saber pays Kei to carry out.
