i would love to hear the backstory on this and how did it go 
imagine the management handing them the new uniforms and telling them to get ready for a photoshoot, they get on the car and hours past, instead of going to an studio in the city the car keeps driving to a rural area in the outskirts of Tokyo, they reach an isolated forest and once there they are told to get down, they notice a patch of dirt where the soil has been disturbed, they get close and discover a hole big enough to fit 4 persons, they look back just to see their managers holding shovels in their hands, the members are simply told "get in there"...
in all fairness that wouldn't be the strangest thing to happen to them, plus BiS members love to hang out in creepy forests, for a while the first generation (the thread is about the 3rd gen) group's image was tied to "Aokigahara", a.k.a "The sea of trees" or "Suicide forest"
and some other good news, member Toggy is back, she has been on hiatus for most of 2022 due to a leg fracture but seems she is fine now
