Hoshitani yells cheerfully, "Let's have a pillow fight!" The other members of Team Otori just stare at him like he's crazy. Then, they say that it's childish.
Pouting, Hoshitani then comes up with a plan to get them to play. He throws a pillow, hitting Tengenji first. Enraged, Tengenji throws a pillow back, but conveniently hits Tsukigami, who gets enraged as well. Then, pillows start flying.
Kuga, with nothing else to do, throws some pillows too. Happily, Hoshitani and nervous Nayuki join in the fight.
By the end, everyone is exhausted and out of pillows.
Panting, Hoshitani cheers, "That was fun!" The others agree as they catch their breath.
Then, they all fall asleep right where they are.
When Otori comes in to check on them, he smiles, takes a picture on his phone, then leaves quietly. He does, put that up as his wallpaper.
