I like Ibara. Eden is one of those units I enjoy but don't produce. He's Eichi's business rival so I like him for that too. Neither of them are very ethical but Eichi is a serious villain while Ibara is just an instigator and thorn in the side (pun fully intended) in stories, imo. Even since before Eichi entered his colonizer arc, I've been rooting for Ibara. My CosPro bias. I appreciate him for taking Rinne in again, even if it was with selfish motivations.
