In part 1, upon first meeting Kamina and Simon, Leeron acts extremely flirtatious around the two newcomers, using a rather graphic array of phrases when around them. Kamina reacts to Leeron with threats, drawing his nodachi and cursing him. Simon for the most part doesn't mind, but still regarded him with concern. Later in the series, Leeron pulls off of his attempts to proposition the boys, resulting in a more cordial relationship, and many times Simon praises Leeron for his work.
