(Please take note that Sealand (Peter) has grown older and so have the other countries.)
A few years after befriending all the Micronations, Sealand has finally become a full-fledged nation. His rocky path into becoming the world's best country has just begun!
Awoken to the sound of clashing metal, Sealand stumbled himself into the kitchen, "Hey Jerk—I mean Senior, I'm finally a bigger and better nation than you are!"
Britain looked back to see Sealand resting his head on the dining table. "Peter, you're going to World Academy starting today, so get ready."
"Okay, whatever," he muttered, not realising what his senior just told him, "Wait, seriously!"
"Of course, you idiot- I wouldn't lie to my own brother!" he tossed the school's uniform at him and quickly made his breakfast.
Peter frolicked around the room and ran upstairs to change, "I can't believe this is happening! I get to go to the same school as Raivis!"
Moments later, they arrived at World Academy where they were greeted by Austria and Kugelmugel. "Good morning, Study Body President," Austria waved at Britain.
Britain nodded at his greeting, "Morning to you too."
Peter ran up to the Nation next to Austria, "Kugelmugel! You're here too?"
"Of course I am. I've been recognised as an artistic country, more artistic then Austria actually..!" He raised his eyebrows a bit.
"So where are the others? Molossia? Wy? And Ladonia!" he inquired.
Australia came running out of the gates in a messy uniform, "Oi, Senior!" he waved to Britain, "Don't ya miss us!"
Britain turned his head towards him, "Us? Us as in whom?"
"Us as in the rest of us Kirklands," Wy walked in, wearing a pink-plaided dress, she looked slightly taller.
New Zealand followed behind, "You didn't forget us, right?"
Sealand glomped the trio, "Guys! I missed you!" they all laughed with joy.
Britain smiled at the sight and said, "Let's get in class now. Come on!"
As a family, they all came into the class; Peter was pretty amazed at how spacious the class was. "Senior!" He looked back at the gentleman, "Where did you sit? I want to sit there!"
"I guess you respect me so much now that you even want to take my seat. I can't even remember how you used to hate me so much now...~" Britain walked to the middle of the class and pointed at the table that laid there.
"Hey, I thought you sat there!" Australia pointed at the teacher's table.
He shook his head, "Let's think of each other as equals, okay?"
"Senior, you seem so calm nowadays! What happened to all those daily complaints?" New Zealand asked.
"Let's just say that I'm turning into 'old news,'" he sighed.
"You mean old— I said nothing!" Wy blurted out.
Right after she said that, all the other students came in and the bell rang.
