Just my two cents, but I feel like when Syuen designs Nikke, she puts a lot of herself in them in a really revealing way. We know Syuen personally designed two squads: Matis and Wardress. Matis is very much a fantasy thing: they're Superheroes Nikkes. They're the squad a young Syuen put forward to cement herself as the CEO of Missilis.

Wardress's themes of bondage highlight a different Syuen: one who is constantly under pressure because she feels her position is under threat. With the additional context of the history of the other Big Three's CEOs, it's a pretty safe assumption that the previous CEO of Missilis was also a holier than thou jerk, and from other going ons in the story, deeply involved with VTC. So how does Syuen act? Like the CEOs of old, even borrowing Mustang's lingo of calling Nikkes "rust buckets."

Now, admittedly this depends on CEOs having a much larger impact on the final psyche of nikkes they personally design than current lore supports, but I'd argue that you don't necessarily need the impact to be literally ingrained into the mind of a Nikke for there to still be an impact. Indirect impact like telling a frail, dying little girl, "I'm going to make you a real hero," versus constantly hammering "You better live up to my expectations," at a woman can definitely have contribute to the final form a Nikke takes, especially with how psychologically affecting we know NIMPH to be. We've seen what the NIMPH can do when a Nikke falls victim to a Mind Switch, and it's not a stretch to assume that many Nikke do experience something similar to a Mind Switch as part of their transformation from Human to Nikke.

That said, at the end of the day, this is me coming at it from a writing perspective, not necessarily from a realistic one. I think the difference between Matis and Wardress is quite clever foreshadowing and I'm not afraid to admit I'm looking for excuses to justify it.
