"Ding— You took advantage of Tokiomi Tohsaka's absence to ambush his wife and daughter, coercing Mrs. Tohsaka onto the path of corruption. Inheriting the Prime Minister's ambition, you have begun your conquest of beauty!
This is a crucial step in your journey toward becoming a true great villain! Reward: 1000 Villain Points, one Epic Summon, and the passive skill [Eyes of Corruption]."
"Ding— Your current Villain Points: 5700. Passive skill [Eyes of Corruption]: Allows you to view a female character's current Corruption Value or Affection Value, making it easier to manipulate them."
"Ding— You have triggered the side quest [The Withering Fall of Aoi Tohsaka]. Quest objective: Increase Aoi Tohsaka's Corruption Value to 100%. Reward: 1000 Villain Points, three Epic Summons, Tokiomi Tohsaka's Magic Circuit (with innate attributes and traits), the complete Tohsaka family Jewel Magecraft, and the Mystic Code: Jewel Sword."
After hearing this series of system notifications, Takashi Kuroda glanced at Aoi Tohsaka, who had returned to her car. Under the effect of [Eyes of Corruption], Aoi's current Corruption Value was 20%—higher than he had expected. It seemed that beneath her façade of loyalty, the Tohsaka matriarch harbored far more loneliness and restlessness than he had imagined.
And now, that long-suppressed restlessness had been thoroughly stirred up by Takashi. He was confident that claiming Aoi was only a matter of time.
"Master, we were busy controlling those servants while you were having quite the enjoyable time with that mortal woman, weren't you?" Stheno's voice suddenly came from behind Takashi. Turning around, he saw her icy, jealous glare.
"You already have goddesses by your side—such an honor—yet you still crave mortal women? Hmph! If that's the case, go spend every day with that woman from now on. I won't care about you anymore." Euryale, too, wore an expression of anger.
"Damn, the harem is rebelling." Takashi chuckled bitterly. It seemed tonight was going to be rough.
Tohsaka Residence
"Master, your wife and daughter have safely arrived... at the Zenjou residence." Kirei Kotomine reported the false information to Tokiomi Tohsaka with a hidden smirk, having already received word from Hassan that his "Lord Dio" had succeeded.
"Don't laugh... Kirei, hold it in. You mustn't laugh." Kirei was thoroughly amused. His master had unknowingly been cuckolded—what kind of delightful expression would Tokiomi make if he ever learned the truth?
Of course, Kirei wouldn't let anything slip. While he sought pleasure, he wouldn't interfere with that man's plans.
"Kirei?" Tokiomi frowned at his disciple's strange expression. Ever since the Holy Grail War had begun prematurely, everything had gone wrong. His plans were in disarray, and his disciple seemed to have developed some odd habits. Though Kirei still carried out his duties diligently, he had recently taken to feeding Tokiomi and Risei Kotomine excessively spicy mapo tofu while occasionally letting out strange chuckles.
If not for Risei's assurance that his son was simply indulging in a newfound interest, Tokiomi might have sent Kirei to a specialist to diagnose whatever ailment he had.
"Yes, Master?" Kirei returned to his usual composed demeanor.
Tokiomi sighed. Despite the recent troubles, at least the relic he had been waiting for had finally arrived safely.
"Kirei, there's no need to worry about Aoi for now. More importantly, the relic we've been preparing has arrived today." Tokiomi opened a case, revealing a fossilized snakeskin.
"This fossil originates from the world's first snake to shed its skin in ancient times. If we use this as a catalyst, we can summon that Heroic Spirit. Once successful, our victory will be assured." Tokiomi smiled with anticipation.
"That is indeed wonderful news. If the summoning succeeds, I shall prepare a celebratory meal in your honor." Kirei replied with a perfectly straight face.
"!!" Tokiomi nearly lost his composure, barely resisting the urge to smack his treacherous disciple with his cane. Kirei's mapo tofu had traumatized him.
"Currently, the known relic situations are as follows: Kiritsugu Emiya has obtained Avalon, Tokiomi has secured the snakeskin fossil, Waver Velvet has arrived in Fuyuki with Alexander's cloak, Kirei Kotomine has already summoned his Servant, and Kayneth El-Melloi Archibald has likely obtained Diarmuid's relic—if he hasn't summoned him already."
That night, Takashi reviewed the intelligence gathered by Zouken Matou's connections and analyzed the current state of affairs.
"The relic related to Lancelot is already on its way. Fortunately, Kariya Matou, though still needing to refine his magecraft, has already manifested his Command Spells. As for me, I'll obviously be taking the place of the original Caster's Master." Takashi took out the Guaranteed Servant Summon and Fourth War Participation Token (Command Spells) he had obtained upon arriving in this world.
After using the token to officially register as a Master in the Fourth Holy Grail War, he turned his attention to the summoning card.
"System, does this Guaranteed Servant Summon work like a regular summoning? Can it be influenced by catalysts?"
"Indeed, it can be influenced to some extent. However, the degree of influence depends on the compatibility between the Servant and the Master. Have you decided what kind of Caster you wish to summon?"
"Most Caster-class Servants are strong, given that this world fundamentally revolves around magecraft and magic. Even Gilles de Rais was a decent Caster in the original timeline. Of course, someone like Medea or Tamamo-no-Mae would be ideal. I just hope I don't summon something bizarre... Well, not that I don't have countermeasures."
"Will you be searching for a catalyst, then?"
"No, I'll summon randomly. Most Casters inherently possess the skills Item Construction and Territory Creation, so summoning one early is advantageous. Raw power isn't my main concern—I already have Mini-Medusa and that incubating Servant for offense, while Stheno and Euryale cover control and support. What I lack is a Servant who can fortify our base. A Caster fits perfectly."
With that, Takashi crushed the summoning card.
A summoning circle materialized on the floor before him, and without the need for an incantation, the ritual began.
"I wonder what kind of Caster will appear through a proper summoning..."
As the radiant light subsided, an elegant, breathtakingly beautiful woman emerged, her lips curved in a bewitching smile. Yet the moment Takashi saw her, his brow furrowed in dissatisfaction.
"Servant, Caster—Semiramis. Hmph... Now, prepare a throne for me. We can discuss everything else afterward. If you don't have one, you can serve as my seat instead." With a haughty laugh, Semiramis unleashed an oppressive aura, bearing down on Takashi.
"This is exactly why I didn't want an overly dominant Caster—trouble like this." Dark lines appeared on Takashi's face. Their compatibility was clearly poor.
In response, Takashi unleashed his own overwhelming presence—not just the [Savior of Evil] aura, but also the dense black mist swirling behind him, filling the entire room. Even the Assyrian queen couldn't maintain her facade, her expression turning serious.
This Master... was far more formidable than she had assumed.
