Before Translation - Tenryuu and Tatsuta... or at least these two who will become them in this scenario... look like the most 'normal' of the bunch. At least insofar that until the translation is done they don't appear to be violent/criminals, victims of abuse, or such. Even Furutaka and Shimakaze are being effectively 'bribed' with the chance of being healed by becoming Ship Girls, so while they seem enthusiastic in their image, it's a different motivation for them.
Of course, considering what the other images/backstories are showing in this series, I'm prepared for some kind of twist on their situation.
So what exactly happened here - did Tatsuta donate an eye? Or did Tenryuu lose both her eyes? I'm confused and re-reading the translation doesn't help make it any better.

Tatsuta tried to donate her eye, but shipgirl can't take human organ. So Tatsuta decide to become Shipgirl instead, to accompanies Tenryuu (become her eye).
The eldest daughter of a family of policemen and firefighters that exert themselves
from generation to generation on protecting the people.
And her classmate, the second daughter of a family that supports them since ancient times.
It becomes clear in this "Tenryuu" surgery
that injuries you get during the process of ship girl transformation cannot be healed.
After she heard about the accident of "Tenryuu"
who undertake surgery before her, she proposed to donate one of her eye.
But when she knew we can't transfer human eye onto ship girls, she said:
—and becomes "Tatsuta".
"From now on, I will be one of her eyes. That is why I'm here after all."
It was expected that those girls would volunteer to be ship girls.
