Leonel returned to the Etching Metal Organization. He thought about going to the Rain family, the last family that had attacked Earth back then, but he decided against it in the end. Unlike the Umbra, Midas, Radix and Florer families, he couldn't promise the Rain family anything that would guarantee their loyalty, they would just be an unwanted variable that might flip at any time.
Although it was impossible to avoid traitors amongst the other families, what Leonel could guarantee was loyalty at the most key positions. This wasn't something he could accomplish with the Rain family.
This was unfortunate. If Leonel could gather up all five of those families, then the Milky Way would have a nice buffer against everyone else.
