A/N:  This only includes the Sakura Empire ship as yanderes. The Royal Navy ships will appear later on.  Please note it's only specific ones, not all of them. Takao is not included as a yandere. 

Characters: 

Takao: Constructed from the commander's base. She's not into relationships but trusts the commander a lot. Wouldn't even dare to marry him, despite being the commander's secretary.

Akagi: After grinding for at least a week in Chapter 3, she was received from the Commander. Her affinity grew fast quickly when meeting him and wanted the commander to herself, even if it means to track him down his real location or going on a killing spree.

Kaga: Akagi's sister. Nonchalant when the commander received her in Chapter 3, she ends up slowly going insane when she's with the commander later on. She even murders other people that dares to harm the commander with laughter.

Taihou: Akagi's friend. After receiving word from Akagi about the commander, she stalks him when Takao isn't around. The commander doesn't even know how did she even find him in the first place. She then takes advantage of the commander, which upsets Akagi.

Atago: Takao's Sister. She has bitter tensions on Takao and tends to scare the commander with bear hugs and taking care of him as a big sister. She wants to marry him to get away from Takao and be forever with him. The worse situation for the commander is that either she sleeps with him or covering his face with her "cushions" or even having some fun. (It's not a lemon.)

Shoukaku: Constructed with passion as an aircraft carrier. She cares a lot for the commander, but she giggles and smiles frequently, giving the commander nightmares of her. She enjoys the commander's scared expressions, causing her to smile and giggle even more and stalks everywhere he goes to the point it's getting really creepy. Her flute-music can charm him, to his death. Feels excited when she's with the commander. 

Zuikaku: Shoukaku's younger sister. She's shy and wants to know the commander more. However, she watches him from a far away distance and plans to get rid of Takao. Goes psycho when she's with the commander alone and keeps writing letters to him. The commander gets concerned where the letters are even coming from. 

Amagi: Also constructed with care. Like Zuikaku, she watches him from a far away distance. The commander keeps seeing her every time and she sits next to him when on break. She wants the commander to be with her and won't stop getting what she wants. 

Souryuu: Was received by the commander during grinding in Chapter 3. Smart, intelligent and shy, she prefers not to get near him. Like Amagi and Zuikaku, she watches and stalks, but also fantasies about him. 

Hiryuu: Like Souryuu, she was also received by the commander in Chapter 3. She gets too protective and pushes Takao away from her and the commander. She also threatens him if he gets near Takao or anyone else instead of her.

A/N: Amgai, Zuikaku, Shoukaku, and Taihou, were from limited time construction as a heads up. Souryuu, Hiryuu, Akagi, Kaga, Zuikaku, Shoukaku, and Taihou are aircraft carriers while Amagi is a battlecruiser and Atago and Takao are heavy cruisers for your information.
