Kapitel 497: You girls have homework? [2/2]

"Cowtits in glasses has orders to hack her in the Minerva server. She'll let us change everyone's name if you do. I only got in once, for a few seconds. Her other mission is to resist being hacked for 24 hours. I am so sick of getting Rickrolled every time she hacks me!"

"The void space pervert, on the other hand, randomly opens holes all over the place. Her task is to close them before things get out. I was blasted by salt water over ten times before our honeymoon. Sometimes even fish come out! But that is still easier than catching the bullets you fired!"
