Eh, Taihou is manageable; the yandere thing is masking self-confidence issues.
Now, if we're talking Akagi...
Akagi is also pretty much manageable, the issue isn't she willing to share the commander with the other shipfus, (she has done that before, especially with that of her own nation, and with her sister Kaga.), the issue is she has abandonment issues, because due to losing her real sister, her elder sister Amagi, and she would do anything to protect that relationship that she has with the commander and with her sister Kaga at all costs, also she isn't a complete yandere either.
