“Len… look.”
Rin sobbed sadly as she showed her brother her arm with a chunk of flesh bitten off.
“Whoa!” Len exclaimed in honest shock. “How did you even do that?”
“They did,” Rin said. “So you have to kill me now.”
“Huh,” Len smirked. “And how do you want to die?”
“I don’t _want_ to die!” Rin protested, bursting into tears. “There’s just no other choice.”
“Right,” Len tried to put on a more serious face.
“You have to destroy my brain so that I don’t turn,” Rin explained.
“Makes sense,” Len nodded and put a long knife against one of her teary eyes.
He wanted to say how much he was enjoying this sudden twist Rin came up with, but knew she wanted him to stay in-character.
“I'm sorry I failed to protect you,” Len said, shedding a tear of his own, “I will never forgive myself.”
Rin opened her mouth to say something in return, but before she could do so, Len pushed the knife all the way in.
Rin produced a short shriek as her body jerked then went limp. Seeing her gone, Len burst into laughter. He still played along by continuing to scoop her brain out of her eye socket, but he couldn’t keep pretending being all serious. When Len suggested they play pretend apocalypse, he had more of the action aspect of it in mind, like running and parkour, but Rin’s little improvisation turned everything into an overboard drama… and it was hilarious!
