[Crimson Moon is pregnant. Yes, that self-willed Moon King Crimson Moon, who acts entirely on her own whims and does as she pleases, is pregnant.]
[You never considered the possibility of Crimson Moon getting pregnant. Because your own bloodline power grows increasingly stronger, you know how difficult it is for you to have offspring. But Crimson Moon's pregnancy is clearly real.]
[Similarly having never experienced pregnancy before, Crimson Moon is also clearly stunned.]
[Of course, as the Moon King, Crimson Moon has seen all sorts of storms. Declaring she wants to give birth to these two children, she begins changing her daily routine for the first time ever and seriously reads human childcare manuals and the like.]
[At the same time, since Crimson Moon is pregnant, you naturally cannot ignore the Moon King during her pregnancy. You declare you will accompany Crimson Moon in the Millennium Castle in the coming time. You, along with the other True Ancestors and Phantasmal Species, alter the terrain around the Millennium Castle, and the area around the castle begins to develop rapidly.]
[During this period, you tell Nero that she can choose to continue staying with you or go to the Roman Capital. Of course, if possible, you think it's better for Nero to stay with you, since the young girl is only 7 years old.]
["Teacher, if you do not mind me, then..."]
[Nero is naturally overjoyed at the chance to stay by your side and has no reason to refuse.]
[In the following time, various Phantasmal Species, either squeezed out of living space by humans or living in seclusion, bring their clans to the Millennium Castle one after another.]
[Among them are long-standing youkai, Dead Apostles who neither want to suck blood nor be enslaved by True Ancestors, elves and fairies who sing poetry and love art, werewolves, wraiths, and many more, totaling dozens of Phantasmal Species races.]
[Gradually, more and more beings gather around the Millennium Castle. With practiced ease, you plan the residential areas for each race and issue various decrees, stating that if they want to be your subjects, they must follow the rules.]
[Under the Earth King's immense power and clearly fair system, the vast majority of Phantasmal Species accept this. The few disobedient ones either flee or are eliminated.]
[It can't be helped. With humanity currently so powerful, if the other Phantasmal Species races do not unite, they risk being completely wiped out.]
[Developing peacefully over time, the Millennium Castle unknowingly becomes a massive entity. Even without any promotion from you, the Earth King, Phantasmal Species across the planet learn of this distant haven, the nation of non-humans, the last paradise besides humanity.]
[Facing the continuous influx of non-human races, you accept them all. Possessing absolute, overwhelming power, you know that as long as you and Crimson Moon remain in the Millennium Castle, even if these beings have conflicts, nothing major will happen.]
[Of course, you also establish a parliamentary system. Each race can send representatives to discuss issues together, similar to ministers, with the final decision confirmed by the King.]
[There are seventy-two members of the parliament. It's a large number, but not too many considering the numerous non-human races. After all, back in Uruk, there were tens of thousands of non-human races, with just the branches of demons and beastmen numbering in the hundreds.]
[The seventy-two parliament members are all powerful individuals. Among them are some who would later be known by the Holy Church as the Twenty-Seven Dead Apostle Ancestors.]
[For example, Gransurg Blackmore, the Black Wing Lord, and Trhvmn Ortenrosse, the White Wing Lord, are both among the seventy-two parliament members.]
[Facing a nation with such a large population base, you understand that while there are no issues now, this country will eventually face huge problems because you cannot stay here forever. For Phantasmal Species and humans to coexist peacefully, a sufficiently excellent King is needed, like Artoria, like Gilgamesh, like...]
["Teacher?"]
[Staying by your side, watching countless races she never dared to imagine prostrate at your feet, the young Nero's emerald eyes show no desire for power. What she wants is actually very simple.]
[Time passes. When Nero is nine years old, Crimson Moon, after a two-year pregnancy, finally gives birth to two children, your and Crimson Moon's daughters.]
["Blood, the children, I want to see them."]
[Her body is very weak, but she holds absolute love for her children. Unlike the True Ancestors, who are imitations, her own children are nurtured bit by bit by Crimson Moon, born from her own bloodline.]
[Taking the two infants handed over by Justice, Crimson Moon sees shadows of you and herself in these two children.]
["Let me see... the black-haired girl is the elder sister. Let's name her Altrouge."]
["The golden-haired girl is the younger sister. Let's name her Arcueid."]
[Giving her children perfect names, just like that, the princesses of the Millennium Castle, the Black Princess and White Princess of the Brunestud Family, make their appearance in another identity.]
[They are the two main heroines of the Tsukihime Series, the characters central to the entire work.]
[The elder sister, the Black Princess Altrouge Brunestud, who formed a blood contract, inherited Ryuya's Beast of the Apocalypse's Self-Modification, capable of transforming twice.]
[And the younger sister, the White Princess, the innocent and kind Moon Princess Arcueid Brunestud, who inherited Crimson Moon's Marble Phantasm, the golden-haired princess.]
["Altrouge and Arcueid... You... are my children."]
[Looking at Altrouge and Arcueid in their swaddling clothes, you have never experienced the feeling of being a father before. But when those tiny hands lightly touch your fingertips, a strange impulse rises in your heart, and you understand… this is a father's love.]
[Smiling happily, you take Arcueid and Altrouge to the highest point of the Millennium Castle and announce to all your subjects that these two children are the daughters of the Earth King and the Moon King. They are natural-born princesses, the princesses of everyone.]
["Long live the Princesses!" xCountless voices]
[As the cheers of the subjects erupt, the magical wave caused by the entire nation makes the world tilt. One can feel the planet's safety developing in a positive direction. The Earth's consciousness, Gaia, feels very happy. Its efforts to gather the planet's fortune on Crimson Moon were not in vain; Crimson Moon indeed became pregnant.]
[The daughters of the Moon King and the Earth King… these two children are naturally the planet's strongest protectors, favored by Gaia. If they wish, they will be the vital links maintaining Earth's safety.]
[However...]
[Originating from human consciousness, wanting the Silver Age of Rome to continue forward, through the subsequent Bronze Age, passing the end of the Age of Gods, and advancing towards the Iron Age, until humanity completes the cycle and starts a new era… Alaya suddenly realizes that the existence of the Earth King and the Moon King will clearly halt the progress of human history.]
[Beginning to stir its thoughts, Alaya decides on a bold idea, which is...]
