Hibiki was incredibly ambitious, wanting to make the Ultimate Coordinator in order to achieve the highest potential of humanity. He even removed one of his own children, Kira, from his wife, Via, who was pregnant with twins at the time, placed him in an artificial womb, in order to make the Ultimate Coordinator. However, Via, strongly objected to creating the Ultimate Coordinator using one of their own children, stating that life should be born and not manufactured, but Dr. Hibiki still went along with the project. Stating that Kira is his son only, and not his wife's, he then sought to make the "Ultimate Coordinator" which to him, would bring about happiness. Soon enough, Ulen is able to perfect the artificial womb, which incubated the perfect son.
At the same time, Dr. Hibiki was approached by Al Da Flaga, the father of Mu La Flaga. Al sought to create clones of himself because he thought of Mu as a failure and not his son. Al persuaded Dr. Hibiki into making clones of him by offering more money to fund his projects, to which Dr. Hibiki agreed.
However, the clones of Al Da Flaga, such as Rau Le Creuset and Rey Za Burrel, all had shortened telomeres within their DNA causing a rapid aging process which meant a short lifespan, and all had to take pills to stop the pain that ensued. Thus, they were all failures.
Soon after the success of his experiment, he was attacked by Blue Cosmos forces. What happened to him afterwards is unknown, but it is presumed that he was killed along with his wife.
