Azur Lane: Laffey, Azuma and FDG (I oathed them)
Other ones I plan to oath are Shinano since she's sleepy and floof and Richelieu since she's fire af.
Probably not Anchorage since she's more of a daughter material.
AK: I'm not sure for the waifus but for husbando it's definitely Thorns. You can paste his face to every waifus to make him a waifu.
After some thought, probably Exusiai, Angelina and Bagpipe. It's hard since I simp on a lot of characters, especially if I love using them and they actually came home.
Also, Exusiai x Myrtle best ship. Mostima shippers don't @ me esp if you endorse that doujin.
