Teitan Elementary School, Beika Town: Their most popular teacher, Rie Fujimaru, has returned from sick leave with two children!
"The boy is named Ritsuka, and the girl is Rikka."
The day after the rumor spread, the gentle female teacher had no choice but to explain this to the crowd of suitors who suddenly showed up at her door, some familiar and some complete strangers.
"They're children from a relative's family. By our family generations, shouldn't they call me Auntie?"
That, however, was a lie.
By their family generations, they should actually call her Great-Great-Aunt.
Fujimaru Ritsuka and Fujimaru Rikka.
They were the children of Rie Fujimaru, the teacher... No, of Chiron, the heroic spirit who won the previous Holy Grail War. Their Master had left them behind, and they had unexpectedly inherited magic circuits.
The incidents they'd encountered lately had grown increasingly bizarre, but surely none of them could have anything to do with these innocent, adorable children, who had just a tiny bit of magical talent.
A day later, as she gazed at the red markings on the children's hands, the wise centaur teacher fell silent.
...It's fine. It's only a Holy Grail War.
Teacher Chiron's expression gradually grew resolute.
At worst, she'll just win again (crossed out).
Even if it costs her life, she will never let evil people harm her young pupils!
...Another day later, as she looked at the summoned Berserker, who called himself Arjuna, and Caster, who called himself Oberon, Teacher Chiron fell into an even more terrifying silence.

The Holy Grail War.
A battle to the death between seven Masters and the heroic spirits they command, all vying for the Holy Grail, which can grant any wish in the world.
The female Master, who seemed to be listening attentively, put on a look of feigned confusion and spoke haltingly: "So, you answered... my summoning?"
But for the heroic spirit Achilles, the honor of having his teacher go out of her way to play along was already enough to leave him completely bewildered.
"Of course. By the way, do you know Ch... I mean, does your ancestry include any centaurs? Or have you ever been blessed by a scorpion?"
--Wonderful.
Ignoring her pupil's muttering, the teacher thought calmly.
With Achilles around, whether it's that child-trafficking organization called Chaldea, the inexplicable sudden increase in Holy Grail Wars, or the strange Servants inexplicably gathering around her children...
The important job of protecting your junior fellow pupils, both mentally and physically, is temporarily and unequivocally yours, Achilles.
As for me, your teacher, I'm going to shoot an arrow with the power of a scorpion and immediately, right now, punish the inhuman culprit who locked these little children in a Singularity!!
