Isamu getting Lucy wasn't a challenge, and Myung was a foregone. As for Sharon, she didn't want to get wit him, she wanted to ram him into the ground.
Basara on the other hand had Sivil cummin' just from the thought of him, and had she stayed in this dimension t hey'd totally be having flying singing guitar playing super babies. I'd also wager that he did get Rex, he's just to smooth to bother flaunting it.
Max is OG sukube and got Milia, but was quickly p-whipped. Basara had the entire Chlore fleet soaking themselves. Basara's pimp enough that he don't need those ho's, though if stupid freakin' Pedro hadn't inturrupted, he'd literally have been in Emilia's pants.
Once again, the win goes to Basara.
