Would it be much more scary if we have a Re-class than a Wo-class?
Wo-class is going to be much more obvious as being something wrong, in an eldritch horror sense, than Re. Re can pass for human, even unintentionally, if she has her tail down. Whereas Wo's headgear and tentacles are more likely to be seen first, before the humanoid bits.
Considering its night and Wo-class is an aircraft carrier, and Fubuki is a Japanese destroyer....Wo should be the one to run. That's way too close to a Japanese destroyer at night for a carrier.
