Yoki and the others were holding back Shipmaster Shadow ships but he was having trouble figuring out anything that can actually work on them but soon after they try to stop them from passing through. Shipmaster Shadow had sent his troops on the Black Widow and got inside of the ships.
Yoki went to check the top and Heather went to check the bottom and the middle of the Black Widow was Irene's job and she was making sure that nobody passed through to the defensive and make it to their favor.
But if only it was easy and the shipmaster troop got aboard. Being small in front and the large in the back and the more aggressive ones are sent in separately and Yoki had to focus on all of them and make sure that they use caution and take all of them out one by one in a group.
