Love interest: Myla Fox, a paramedic for the Holland Hospital (fictional place, keep in mind)
Job: Part time assassin, part time firefighter (for now at least), and helps out in Akita's store a lot. Might drop the firefighter job because of the people there
Personality: Introvert, judging, but usually quite cool. He's the sort to just hang out and joke around, playing video games. He's also good at paying attention to details. He's good at pointing out things, and hates stupidity. He also is very very intelligent, and good at being on time. He doesn't like people who mess with anyone he cares about, so his anger is quite cold.
Backstory:
He's Akita's younger brother. He doesn't remember everything from what happened with his father, but he remembers enough to know exactly how terrible it was. He hated being related to a murderer, and hated what his father did to Akita and Lani. It was enough to turn him a little cold, a little too used to that environment. So once they were free of Flynn Williams, he changed his last name to his mom's name, Romero. Leo always wondered how, no matter how much they had all tried to erase it, the past kept coming up, even when he and his siblings were living with Azora & Ash. He was severely bullied, and Akita had to step in a lot, to keep him from getting hurt. When he was around 16, Azora, who he saw as a mom figure, was killed. This started to convince him that he had to be tougher, stronger, if he wanted to survive. So after that, when Akita got the store, he started training with her to learn self defense and other fighting things. He's now skilled in martial arts, and quite the protector. Soon enough, he figured out Akita's job after following her one night. Then, he started joining her on her missions. He's pretty good at being an assassin. Oh, and he just graduated!!!
Other info: Ash dyed his hair as a test to see what all she could do for crazy ideas.
