Happened a few years after senior highschool.
Hiruma went home straight after his death-defying training from his American football team in college. It seemed that the former Deimon Devil Bats crew (his batch) was still at its grip since almost all of his teammates in highschool tried and were able to pass the college he's in. Of course, it included them joining the American football team there. Reality wise, new people emerged, but everything was on its normal state as is, failures and success at the edge. Now it was as if nothing had changed, Sena still the Eyeshield 21 of the college team, him still the manipulative captain, and Mamori still his manager. Thinking of the years passed, there was one change, Mamori and Hiruma were married and have been living together in a while now. It happened all of a sudden, as hell stroke and touched heaven.
Dropping his bag, he saw Mamori sleeping sound on their bed. She went home earlier to do her college homework and to contemplate on some new strategies for the team while watching the games of the opponents. Not trying to wake her up, he moved quietly. But still, his manager moved as if in quick reflex, sat and looked at him with a smile in her face.
"I'm fucking exhausted, those damn pipsqueaks sure know how to tire me," he said, quasi-awake.
"Come here," Mamori said, opening her arms for him.
Collapsing on Mamori, in between her legs with his face resting on her chest, due to extreme fatigue, she had nothing to do but to snuggle with him to ease him up. She planted kisses on the quarterback's spiky hair.
"Don't do that or else you don't want me to bring you to holy hell in no time." He smirked, still half-awake, teasing.
"You know, that's what I'd rather call heaven," as she laughed silently with their naughty little talk... "Anata...?" She smiled as she realized that Hiruma was already fast asleep in her comforting arms.
Note: Anata means 'my dear' in which it is also the sweetest way to call your spouse in Japanese. Actually, Hiruma gets really pissed whenever she calls him that, but hey, she was teasing him until she noticed he's already asleep.
