Okay I get why Akagi is gluttonous, but why is she trying to eat a fan
Well, it is an aircraft catapult. 'though here it's more like she's trying to eat Nisshin and Nisshin responded by fending her off with what she had (literally) at hand.

Not just a fan, but a Tessen which is an IRON war fan.
You don’t try to reason with Akagi’s hunger. When you sound like a particular brand of instant noodles (or resemble any sort of food, like Urakaze’s/Kongou’s hair donuts), all you can do is run.
