Mashu Kyrielight and Ritsuka Fujimaru

"Hurry Senpai we're late." The young woman with short pink hair called out as she ran down the halls. She was Mashu Kyrielight a Demiservant created by the Chaldea Security Organization to aid in the preservation of humanity. She was a Shielder class servant, the only of her kind.

"Alright, I'm right behind you," The scruffy haired young man said as he ran behind her. He was Ritsuka Fujimaru a fairly unremarkable mage who had joined Chaldea on a whim. Now he was the last Master of humanity.

Together they were the unstoppable Master and Servant team that had saved the world several times as agents of Chaldea stopping the Incineration of Humanity and several other singularities from wreaking havoc on mankind. While things were peaceful now, new threats could pop up anytime, so the pair had to be ever vigilant.

"Hey, did Da Vinci say what this meeting was about?" Fujimaru asked curious what their Technical Advisor needed from them. A servant herself Da Vinci had been a big help throughout Ritsuka's tenure at Chaldea.

"I'm not sure," Mashu replied glancing back. "She didn't say anything about a new singularity forming but since we're heading for the observation deck it must be something important."

Fujimaru nodded and the two soon made it to the observation room. It was stark white like the rest of the facility but with a massive bay window on the far side used to observe CHALDEAS, the model earth used to predict worldly disasters. Staffer sat at terminals furiously typing and analyzing data from the illuminous blue orb for anything that could threaten the future. In the center of the room sat the Chaldean Heroic Spirit Da Vinci, a brown-haired woman in red and blue dress with a massive mechanical arm. Dispite this odd accessory she took a sip from her teacup with precision and elegence before spotting the pair enter the room. Her face quickly lighting up happy to see them.

"Right on time you two." She beamed. "I hope you're ready for this."

"Yes ma'am" Mashu relied quick as a whip. "Although we still have not been briefed on this next assignment."

"Is it a new Singularity? A Lostbelt?" Fujimaru added.

"Oh no nothing like that." Da Vinci shook her head. Her smile grew wider. Whatever this was about she was certainly excited about it. "Today you two are going to face something new. A special training simulation designed by your's truly."

"Training simulation?" Mashu pondered to herself. "But we already have those? Why riase the alarm?"

"Yeah how is this different from the missions at the Gate?" Ritsuka asked.

"Oh, it's very different, Fujimaru." Da Vinci smirked. "It's almost as immersive as a full singularity. Or seven to be exact."

"Seven?" Mashu tilted her head. "Wait are you talking about the seven singularities from the incineration of humanity!?"

"Those very ones," Da Vinci sang holding up a finger from her mechanical glove. "Mashu Kyrielight. Ritsuka Fujimaru. I hope you are prepared because your about to speedrun your first year of mission all in one go!"

"HUUUUHH!"
