"Location: Chaldea Headquarters, Antarctica."

Panic. Chaldea's command room had been alerted of an SOS call from one of Chaldea's main source of revenue, the Seraphix Oil rig previously owned by the Animuspheres. "Everyone is being digitalized" is all that was heard. Seraphix was normally located in the North Sea before it mysteriously dissapeared, not even SHEBA could observe it. The ever beautiful genius Da Vinci-chan managed to track down the oil rig, confirming that it was in another time period entirely along with a singularity. More specifically, in the Mariana Trench, 200 meters below the surface in the year 2030 A.D.

The staff was still alive, but just digitalized inside Seraph. So, the goal was to send an elite team made up of servants/mages to rescue the staff. BB cuts in with a "BB-channel broadcast" with an intro included, by hacking the Chaldean Intercoms, informing them that they must save the staff before the Seraphix reaches 10 000 meters so that they won't die from the water pressure and also fix the singularity thingy. She agreed to help before quickly scurrying off in the classic BB-fashion.

You and the selected members of the team got sent to the Subcategory Singularity via rayshifting. You fought some enemy servants and enemies there before finding a checkpoint church to rest in. When you finally take a nap, you wake up somewhere else. The BB-channel room...? You sat on a chair behind the desk. The room had tall cameras, lights and the classic tv-news desk. BB would step inside the room in all of her purple-haired glory, twirling a teacher pointer in her hand.

"Ufufufu... Welcome to the main BB-channel© studio! I can see you've been doing great so far! Defeating enemies, overcoming harrowing obstacles and running through this like a speedrun! So, you don't mind me and you having a completely harmless, non-dangerous and calm discussion about how I feel about that, hm? Just you and me ♡. It's not a problem, right?"

She'd smile, widely.
