Not like they have any choice.

One rayshift later and the group arrived in a open area with a digital sky, and ground made out of transparent cubes. "How do I always end up here?" Tamamo asked while everyone else looked around checking to see if BB or any other enemies were around the area.

"This is a very strange place." Barghest said never having been to the Moon Cell before.

Mash, now in her servant outfit and appearance with Galahad's shield at hand. "I missed your last trip here Senpai. Is there anything we should be aware of?"

"Just that enemies can appear out of nowhere." Ritsuka said adjusting from the semi-rough landing.

"Bring em on!" Mordred punched her hands together. "Nothing this place can throw at me will stop me!"

"Welcome contestants!" A holographic image of BB appeared in front of the group with a big smile. "Before we move onto the first event, let's make sure our competitors know the rules of the game!"

"Just give up and hand over the grail now and save us all some time!" Mordred yelled at BB.

"Oh we have a fiery one this time folks! Maybe I should prepare a special challenge just for her now!" BB's eyes turned red again. "Make sure you listen so you don't break the rules."

"What are the rules?" Barghest asked standing close to Ritsuka to protect her.

"Glad you finally asked!." BB was back to having a big smile on her face. "First of all, no metal armor allowed!" BB took her baton and pointed it at both Mordred and Barghest as their armor glowed and then vanished. Leaving Mordred in her standard red top and bottoms, revealing how small her chest actually is, and Barghest in her black dress she wears during casual events, revealing that under her thick armor was a rather large chest. Both of them had shocked expressions on their face with Mash, Tamamo, and Ritsuka also caught off guard. "Don't worry. You won't be needing any armor for this game!" BB said in a cheery tone, "Now for the second rule! Each challenge can only be taken on by one servant at a time!"

The group looked back and forth at each other in worry about that rule. "Wouldn't that have been handy to know before the team was formed?" Mash asked BB

"Perhaps, but where is the fun in knowing exactly what you're up against?" BB said with a giggle. "Third rule is that each Servant has to attempt a challenge before one can go again! Can't have you just rely on one to brute **** through all I setup after all, Senpai. Final rule for now is when whoever decides to take on a challenge I spin this!" BB raised her baton up as a BB Slots machine appeared above them with various different icons on the slot wheels. "Whatever it lands on will effect the challenge in various ways! I look forward to seeing your reactions to each one!" BB pointed the baton away from the group as a door appeared. "You're first challenge is beyond that door! Have fun Senpai!" BB's hologram then vanished.

"I made this team thinking about how you all would help each other, but only one at a time makes that pointless." Ritsuka said a bit dejected.

"Don't worry Master! Your lovely Tamamo will easily take care of any challenge I step up to!" Tamamo said trying to cheer Ritsuka up.

Mordred was obviously grumpy over the **** loss of her armor, and was also glaring a hole through Barghest's chest before she finally noticed. "Is there a problem Mordred?"

Mordred grunted. "No problem at all. Let's just get this over with." Mordred started walking over towards the door BB made for the first challenge as everyone else followed.
