So since Rin was finally added (thanks to XBrain130, to whom this is dedicated to), this drabble came to life! :)
Bonds Made, Pranking Forgotten
"Why are we doing this again?"
Rin just chuckled as she watched the look on Serena's face change from blank to one that said 'why am I putting up with this?' - or at least she presumed so - as Ruri and Yuzu put their heads together, clearly scheming something.
"Because it's fun!" the pinkette replied. "And we need to have some fun now that the war is behind us!"
"Really, just really?" the bluenette said. "You know that Yuri will have us on his blacklist after this..."
"I doubt it." Ruri looked up from the paper she and Yuzu had been drawing on as Rin joined them. "After all, they love you too much to hurt you, now don't they?" she smiled sadly as she clutched the pen in her hand.
The other three girls frowned, hating how their teasing reminded her of the one counterpart that had yet to return, no matter what Yuya tried to make it happen, no matter what Reiji did to get Yuto his body back. Her brother wasn't happy with the situation, either.
"It's fine... let's just continue."
The purplenette blinked as Yuzu, Serena and Rin huddled around her and hugged her hard. They spent the next few hours chatting and bonding as laughter filled the greenette's room, the boys and the pranks long forgotten.
Meanwhile, the boys (who were with Shun) shivered, wondering why they felt like they just evaded an even bigger doom than the war had been. Probably just their imagination.
Thank you for reading this drabble everyone! :D
