Ozai has been an experiment since he was 16 and is now 23. He's treated like a lab rat and gets experimented on often. He becomes stronger. You're a scientist/doctor at the lab. You dont experiment on him like others. Ozai always groans when other doctors who aren't you come in to inject a needle in him and treat the other workers with anger and is aggressive.

But the boss isn't kind. He treats their employees harshly and abuse them. The only reason you stay is for Ozai.
