The anime's ending leaves a great deal up in the air; this story takes up some of those loose threads. Picks up immediately after the end and throws everyone a little further into the future.
"Takuto is with him," Wako said firmly, eyes fixed on the sky. "They'll be all right." Takuto's look had promised her that, in that long, silent moment of fierce understanding they'd shared before she'd agreed to break the southern seal. And she was going to hold them both to that promise, if she had to regenerate Wauna and go up there herself to make sure of it!
- Part 1 of Triskelion
Wako has an epiphany and decides it's time to break the deadlock between her boys in a way neither of them anticipated.
Was that what they'd have to do, to stay together? Not let anything be romantic or... or anything, between them at all? Because, for all Shinada-senpai teased their schoolmates sometimes, none of those three had ever dated anyone. Certainly not each other.
- Part 2 of Triskelion
The drama club is putting on a play with some scenes worth of Wako's fantasies. Takuto has to work a little to wrap his brain around the whole thing.
"We are the future of the world." Sugata's words filled the space, low and intimate. "What do you wish to make of it?" His thumb stroked over Takuto's lips slowly and Takuto felt his whole face flush hot.
"I... um... The... The world..." Takuto's hands scrabbled at the wall behind him as Sugata leaned closer. "Help...?" he finished, strangled.
The corners of Sugata's mouth quivered as he looked at Takuto. One breath, and then two, and he finally lost it, dissolving into helpless laughter.
"Takuto-sama!" Yamasugata-senpai scolded. "If you forget your part, the word is 'line', not 'help'!"
