Oleander, or "Lea", was a pretty normal college student. He majors in engineering, which is why he made Nano. He lives with his bestfriend Lycoris, and hus boyfriend, Strelitzia. He and Strelitzia were the parents of the small robot boy, while Lycoris was just a close friend who hung around. Oleander is the one who built Nano's body, while Lycoris did the coding.
