In a Pinch with a Battleship's Big Cannon!. Akeno becomes anxious over putting her crewmates in danger again as the Harekaze is sent to pursue the Musashi. While the Blue Mermaids try to rescue and stop the Musashi, Moeka, who has been trapped on the bridge with a few crewmates, recalls how the rest of her crew became infected and took control over the ship. As the Blue Mermaids ships begin to diminish under the Musashi's firepower, Akeno expresses her fears about letting her crewmates get hurt. Receiving some advice from Maron, Mashiro and the rest of the crew give Akeno their support, encouraging her to take action and head off to rescue the Musashi.
