DESCRIPTION:
Here we go, more subbed Kancolle. This one was tough!
So if we take a look into the booklet, we can see both Kongou and Haruna fighting against two abyssal princesses (the Symbiotic and Airfield ones), with a higher focus on Kongou.
Following the lyrics, seems like the abyssals get their asses kicked. However, they also get to bring the ships along with them to the bottom of the sea...

Willing to get back to Touhou soon™
