Gudako Fujimaru (Fate/Grand Order)

Another day, another singularity resolved. It was an odd one though. It was a mad dash around alot of rooms set up like a maze, each room having different rules they had to do as they fought their way through. It was odd, but they had to follow the rules. Like fighting those eldritch starfish while naked and doing bunny hops, or sucking their thumbs when fighting that Frost Giant.

In any case, she was glad they were done with it, clobbering that phantom at the end and claiming the grail. Which was in the form of a pen?

"This is definitely an odd one." Sion said as they debriefed, putting the pen on the table. "It definitely showed the magical energy of a grail before, but now it's practically empty."

"Well, it was a micro singularity." The little Da Vinci shrugged. "It might have lost most of its power after the singularity resolved. Never seen anything like this before, though." She looked over the pen again. It seemed to be quite fancy, the casing an almost solid gold surface, bringing to mind the Holy Grail (down to the patterns) with a pointed tip at the end, the effect making it look like a mechanical pen had the tip of a quill you saw in a lot of fantasy shows.

"Well, it seems harmless right?" She interjected, leaning forward in her chair as she got a closer look at the pen, head in her hands.

"Yes, but don't forget how often we've run into things that 'seemed' harmless, Senpai." Mash, the violet haired Shielder class Servant (and adorable kouhai) replied, sitting back as she adjusted her glasses. It was true, but that had mostly been inside said singularities. On the other hand, they had had problems occasionally try to attack Chaldea from those singularities, so it was probably for the best to be safe.

"Still, as far as we can tell, it doesn't even have the energy of a holy grail anymore, though it could still be filled with it... Normally we'd just put it in Grail Storage, but given it's Gudako's we'll give it back to you." Sion said with satisfaction, the rest of the room nodding along... until the last Master of Humanity processed what she heard and her arms dropped out from beneath her head in shock, her chin bouncing off the table.

"Ow! Wait, it's mine?"She asked incredulously, ignoring her beloved kouhai's concerned cry of 'Senpai!'

"Yes. while we were studying it, we came upon your name on the pen." Da Vinci nodded, the Rider grabbing the pen and turning it over, showing the name Gudako Fujimaru's on the other side of the pen, standing out in a neat black against the shimmering metal...
