A member of the Iron Blood whose nickname is "Zed." She's always looking for ways to improve herself, and she's also passionate about research. She's very critical of herself and others, but will always give praise to those who she deems as worthy. She's often found acting as a commander in battle. She was chosen to represent the Iron Blood in the Joint Military Exercise by her peers. She's doing her very best to rise to the occasion and lead her friends to victory.
Bismarck is the leader of the Iron Blood fleet, but she disappeared from the frontline after the official battle against Hood and Rodney of the Royal Navy. She's kept a watchful eye on the Sirens since they appeared, and was somehow able to gain access to the Siren's technology. She's calm and generally keeps to herself, so some mistake her as being cold-blooded, but, on the contrary, she is very passionate. She didn't want the Iron Blood to get involved with the Joint Military Exercise, but Kaga and Bismarck's younger sister convinced her to take part. What Bismarck will experience from the event is yet to be understood...
An Iron Blood elite who knows her way around the advanced technology that her nation has researched. Her aura is seen as mature and alluring. Outside of missions, she is very free willed, making it hard to predict what she may be thinking in any moment. As soon as she engages in battle, however, she annihilates without mercy. It's hard to know why she thinks the way she does. Her older sister, Admiral Hipper, is always on her case. She joins the Joint Military Exercise to oversee Z23 and to ensure that their place in the world will not be marred by whatever is to come.
Secretary Ship/Battle Support-Only (Unplayable)
An elite of the Iron Blood, and older sister to Prinz Eugen. She's similar, yet distinctly different from Prinz Eugen in that she acts irritated in front of those that interest her... a typical tsundere. Hipper doesn't enjoy that Eugen knows this facet of her so well, but that doesn't mean they don't get along. Hipper was invited to the Joint Military Exercise as support. At first glance, it seems like she didn't want to participate, but in truth, she's excited to meet Eugen and the others.
The Iron Blood's energetic and rambunctious submarine. She loves to play tag and acts like a child, but her prowess in battle has brought her along to many missions. She joins the Joint Military Exercise with mixed feelings. On one hand, she's worried she won't be able to play like she usually does. On the other hand, she's hoping that she'll find friends who will join her in her game of tag. A certain someone has asked U-81 to buy something, but it looks like she forgot about it already.
