Hana did everything she had to do with Clovis. She first read the research to make sure the potential was indeed limitless.
After that, she negotiated the terms with Kanaria. While Kanaria wasn't at her level, she was the best one to take care of the negotiations in the team.
At the same time, Hana had to be extra careful when dealing with Clovis, especially with the Hacfield family behind him. If she ended up angering the Hacfield family, she would be in trouble. Her family would punish her instead.
This was what Hana meant by saying that everything was useless unless they had a Tier 9 human.
Hence, during the negotiation, Hana offered an extremely generous contract for Clovis's group.
She couldn't help but imagine that if her family had the backing of a Tier 9, they wouldn't have to worry about Michael Hacfield. Even during the negotiation, they could be more proactive and get as much as possible.
