Hell he seemed to be on good terms with people like Selen the few times they interacted, I doubt he was happy hearing about her graduation either.
If anything I'd be real fucking scared if I were Elira, or any other EN talent currently staying in Japan, because Riku is no longer the silly looking kid you see in old photos or video stills, the kid who would probably act chummy and casual with you. He's now the grown up, angry businessman seen in the OP who signs your checks and is getting increasingly sick of your shit. It is not hard to imagine him staring daggers into the soul of any person affiliated with EN from here on out, should they ever have to cross his path.
