I'm tempted to put this in either the Heartwarming or Almost Heartwarming pool, but I can't tell whether all of them are only happy to see Nimu for the Orel Cruising or just Ro and Shioi.
Iku and Decchi are at least genuine in their feels. Nimu is a Type B Sub like Iku, making them sister ships, and Goya is just an improved version of the B Type, so she's often treated like a cousin to Iku, and thus Nimu.
