it has been 2 years since Illya was brought back to Fuyuki,
at first, after learning the truth, she did not know what to do, but after Kurono informed taiga that she was the daughter of Kiritsugu, she immediately forced Illya to enroll in the middle school along with Shirou,
Kurono used a complex runic ritual to remove the adverse effects on her body caused by the modification that the Einzberns had done so that she would serve as the lesser grail for the upcoming grail war, this ritual allowed her body to start growing once more, it also extended her lifespan of 19 years into the average human lifespan of 70 years,
after that, she grew very attached to her brothers and called Shirou 'onii-chan' even though she was actually a month older than him, she called Kurono as 'Kuro-nii', at first Kurono did not know whether to laugh or cry because it literally meant 'Black', but he then let it be,
during this period, he had also come across a girl called sakura matou, at first, he recognized her as the heir to the matous that the clock tower had informed him about, but after using his senses, he was horrified at what he found in her,
A girl that was the age of his brother was being experimented on, in the most horrific way possible,
that night, he went to the matou house and thoroughly exterminated Zouken makiri, he then went towards the girl's room and was stunned at what he saw, her own brother was torturing the poor girl in unspeakable ways, the enraged MAGE used strategic class magic-Soul Eater to destroy the soul of Shinji matou, he then forced the girl to sleep and then removed her memories related to the night's events, he took her to a nearby hospital but not before causing a fire to spread throughout the matou house, he also stored away all of the makiri and matou archives using a master class magic- dimension space,
after that day, Taiga had become the guardian of the newly orphaned girl and had her move in with her, Kurono decided to give her the matou archives when he deemed her ready,
it was also around this time that Shirou met another girl called rin tohsaka, she revealed herself to be the second owner of the city and demanded what the Emiyas were doing in her city, Kurono soon informed her about his association with the clock tower and his rank, after that , she became very respectful towards him but that respect did not extend to Shirou, she also behaved strangely whenever sakura was in the house with Shirou,
-------------------------------
in the Emiya family workshop,
we can see two young men sitting on the ground surrounded by a strange runic circle, one of them was 20 years of age while the other was 17 years old,
this was Kurono and Shirou,
it had been 2 years since the Emiyas had met the Tohsaka and Sakura, in this time, their sister and the two girls had become great friends, however, Kurono was the only one who noticed the growing affection that Rin and Sakura had for Shirou, he decided to let his brother figure it out by himself,
Kurono turned towards his brother and said,
"How are you feeling Shirou?"
"I told you that i am fine nii-san, honestly, i doubt even an expert spiritual doctor would be able to transfer Magic crest as good as you," he said,
a month ago, Kurono had determined that Shirou's mindscape, or as it is called in this world, the reality marble, had fully matured, so he decided to pass on the Emiya magic crest to Shirou,
normally, the magic crest is only passed on to a blood-born child of the owner, trying to pass it on to non-blood related children is very fatal, however, Kurono used his mastery over runes to create a bounded field of perpetual recovery, no matter what happened, the person inside the bounded field cannot be harmed in any way, thus he had managed to successfully integrate the Magic Crest which contained 50 high-quality magic circuits with time-related sorcery trait,
Kurono then said,
"since you are feeling fine, how about we begin the summoning?" he said,
after Illya had informed them that the holy grail was not destroyed and that it was going to begin much sooner than before, the two brothers had begun to prepare for the war,
Shirou had perfected his own form of projection, Tracing, and had gained access to his reality marble, although he was unable to manifest it yet, he decided to use the scabbard that Kiritsugu had implanted in him as a catalyst, although he did not know to which heroic spirit it was linked to,
Kurono helped Illya get the Axe-sword from the now ruined Einzbern castle as her catalyst,
Kurono himself had gained a catalyst that would allow him to summon a ruler class servant, a certain staff belonging to a person that was once known as the omnipotent one,
However he had also noted that Sakura had gained command seals of her own, so he secretly helped her get a small piece of chain from an ancient Greece city that was supposedly connected to the legendary Gorgon,
Kurono watched as Shirou chanted the ritual for summoning, the circle glowed brightly as the room was soon covered in dust,
once the dust cleared, a beautiful woman wearing a blue battle dress stood in front of them, both Shirou and kurono recognized that she had some sort of invisible weapon in her hands, she then turned towards Shirou and said,
"I have come here in response to your summon, I ask of you, Are you my master?"
