The pairing is Ichimatsu!
A slice-of-life story
What would happen if an easygoing guy with superpowers ended up among a bunch of shut-ins?
▲ A story that won't appear in the novel
Suppose Osomatsu tells his brothers he has superpowers:
"Huh? Superpowers?" Ichimatsu says, half-lidded eyes and a nonchalant tone.
"Yeah."
"If you really have them, big bro, make this cold winter turn into summer, please~" The youngest, curled up under the covers, shows only a tuft of bedhead and speaks in a muffled, equally nonchalant voice.
"Can't do that. It would violate the laws of nature."
"Then give us a bunch of warm girlfriends," says the eldest, lying under the covers and picking at his foot.
"Can't."
"Good! Awesome! Give me half of that setting... Yo-shi! Abracadabra! Aya-yayaya! ..." Karamatsu, too cold to feel a thing, flails around under the covers, trying to summon something or other.
"I'm terribly sorry, but I can't give you that."
The eldest pulls the covers tight around himself and Karamatsu. "Aah, the cold air's getting in, you jerk..."
Then they start making a racket and even have a pillow fight. By the way, Jyushimatsu still hasn't woken up :-D
Osomatsu smiles wearily, silently turns up the heat in the room, then hurls his pillow hard at Ichimatsu!
