Why do they gotta follow the herd? You have to get the best photo, not just pose naked.
Shinra with his fire skills, Arthur with his sword, Hinawa with guns, Engineer guy doing engineer stuff, even litch could be doing some science stuff, then Obi in the middle doing, something with his muscles or one of his stupid stunts. Throw a bit of a creativity and photoshop and boom the best photo.
But who am I kidding. This chapter was a filler. They didn't bother showing previous photos of others or even 8th. They didn't show the photos they took this time around. So yeah, nvm, what a waste of chapter.
