When Hertha returned with the first aid kit, Eva went straight to work patching up the red-haired captain. She did just as Handel had instructed earlier and dabbed ointment all over the worse of Eden's wounds. Then she bandaged him up while she listened to Hertha introduce herself. Honestly, Eva would have never guessed she was a giantess. She had seen quite a few of them during her travels with her deceased uncle and knew they were a lot taller than she was. Still, she claimed to be the daughter of a famous giant pirate and she wasn't dumb enough to challenge the woman's claims. 

Once she was finished bandaging the captain up, Eva packed up the medical equipment before standing up. She heard Handel say he wanted to hear everyone before introducing himself. Another smart decision.

"The name's Eva Solkreuz. I'm a bounty hunter who's specialty is hunting pirates," She eyed Eden for just a moment, "However, I have made a deal with your captain and will be working for safe passage to another island. So for now, I will act as this ship's sniper. I prefer rifles and pistols but I know my way around a ship cannon. My navigation skills are adequate and, as you have seen, I have some first aid knowledge. I also have wind powers thanks to the Kaze-Kaze no Mi." The logical side of her wanted to add on that she wasn't particularly good at her wind powers yet, but her pride held back that information. There was definitely no reason to tell them, especially when she didn't know if they would remain an ally throughout the entire journey.
