The wedding with Sola was set for three months away, leaving Haruka Kasugano with quite a bit of free time. During this period, he received an invitation from Waver.
He arrived at the El-Melloi office. Following Kayneth's death, the faction had crumbled, leaving only the Archibald and Sophia-Ri families. They were burdened with massive debt. Furthermore, with the loss of Kayneth's Magic Crest, many secret arts were gone, and Waver was tasked with the grueling job of restoration. The situation was a mess, but thanks to Waver's competence, things were steadily stabilizing.
"Why did you call me here?" Haruka Kasugano asked, getting straight to the point.
Waver didn't waste time either. "You are the Master of Caster, aren't you?"
"I am. Do you want to settle a score? I don't recall having any beef with Rider. Besides, I killed Archer; consider that me avenging you," Haruka Kasugano smiled.
Waver shook his head. "I want to thank you for that, Mr. Haruka. But my main reason for calling you is to invite you to represent the Clock Tower in the Great Holy Grail War."
"Recently, the Yggdmillennia family in Romania claimed they obtained the Greater Grail. They've declared the formation of a new Mage's Association to challenge the Clock Tower's authority. Since they have already summoned Servants, we have utilized the Grail's reserve mechanism to trigger a 7v7 Great Holy Grail War."
The Great Holy Grail War?
Haruka Kasugano thought about it... something felt off. In the original Fate/Apocrypha timeline, Darnic Prestone Yggdmillennia located the Greater Grail during the Third Holy Grail War by using Fionn mac Cumhaill's thumb and stole it. But since the Fourth War had just happened in Fuyuki, the Grail clearly hadn't been moved. Where did this one come from?
"Where did this Greater Grail come from?" Haruka Kasugano asked bluntly.
"We aren't entirely sure. We only know it differs significantly from the one in Fuyuki. Whether they are connected remains unknown," Waver replied. "You are a survivor of the last war and a master with Servants at your command. we desperately need your experience."
"Oh? You want me to fight for the Clock Tower?" Haruka Kasugano couldn't help but chuckle.
Honestly, because of the shifting timelines, he hadn't expected to participate in this specific war. But now that the opportunity had arisen, he was looking forward to it. After all... Jeanne d'Arc, Semiramis, and that girl in the wheelchair (Fiore)—they were all top-tier beauties!
Hehe. Come to think of it, when Rufleus asked for his "help" earlier... he was likely referring to this. After all, the Department of Evocation was responsible for procuring Saint Graphs and Relics for the participants.
"Fine! I've just become the son-in-law of the Eurifis family; it's only right I offer a 'contribution' to my father-in-law," Haruka Kasugano laughed.
"Very well. The Department of Evocation will arrange your catalyst," Waver said.
"Sure. By the way, why aren't you participating? You have plenty of experience," Haruka Kasugano asked curiously.
"I... I am not mentally prepared yet," Waver closed his eyes and sighed.
Hmph. Such a dramatic man. Haruka Kasugano ignored him and left.
As he walked, he used his [Mathematical Thinking] to plot his strategy. In the original plot, the Overseer, Shirou Kotomine, would gather all the "Red" Masters to steal their Servants. Only Kairi Sisigou and Mordred were cautious enough to avoid the trap.
If Haruka Kasugano avoided the trap too, there would be two "rogue" factors. Shirou would be short one Servant, and the plot would derail. While Haruka Kasugano was strong, he couldn't take on 7 Servants at once. He had to stick to his specialty: playing dirty.
To keep the plot on track while securing his advantage, he had to—kick Kairi Sisigou out of the war and take his place.
...I might even be able to summon Mordred directly! Mordred... she was fresh and juicy as a peach! Hehehe!
--------
The next day.
Ring! Ring! Ring! The phone on Waver's desk screamed like a death omen.
"Hello, Lord El-Melloi II speaking," Waver answered, sounding impatient.
"What? Kairi Sisigou arrived in London yesterday and immediately got into a car accident? He's in no condition to participate?"
"..."
"Fine... I'll activate the backup plan..."
Waver hung up, feeling a massive headache. Why a car accident of all things? Well, with Haruka Kasugano participating, losing one necromancer isn't the end of the world. I'll just find another magus.
--------
The next day.
The roster for the Clock Tower was finalized and distributed. Haruka Kasugano lay in bed, reading the list. To his delight, he had indeed replaced Kairi Sisigou. The other six Masters were identical to the Apocrypha plot!
This meant the war would likely follow the original script. Jie jie jie jie!
At that moment, Artoria alter was draped across Haruka Kasugano's lap, enjoying a "lollipop." She had become deeply addicted to the sensation. No longer satisfied with simple licking, she had become an "artist," developing new techniques like the "Spirit Snake Emerging" and "Emperor Circumventing the Pillar."
After countless hours of "strenuous training," her tongue—already incredibly flexible—was like a nimble little snake. Her speed and technique had reached staggering levels. This was no longer a simple organ; it was a peerless treasure.
"Ah~!" Haruka Kasugano reached his limit.
Squelch—
"Mmm~" After her fill, Artoria alter lay back to rest. Her slender frame was sprawled on the bed, her platinum hair spilling over Haruka Kasugano's lap. Her snowy legs were long and graceful, her skin as smooth as suet.
Just then, Melusine walked in. "Master, I pushed that man and his car into the ditch last night just like you asked. I wasn't spotted, was I?"
"Probably not. But even if you were, it doesn't matter. Our goal is achieved," Haruka Kasugano laughed.
"Good~!" Melusine looked at the "lollipop" Artoria alter had just enjoyed. Seeing Artoria alter's satisfied expression, she couldn't help but swallow hard. Watching the intimacy around her for so long had made her curious.
Haruka Kasugano noticed her staring. "Melusine, do you want to try?"
"Eh? I... is it really okay?" Melusine asked bashfully.
"Come here!" Haruka Kasugano was excited. This would be her first time.
Melusine gently shed her clothing, her small body unfolding like a blossom—a tender, budding flower. Despite her loli-like stature, her unique charm was intoxicating. Like Artoria alter, she possessed a different kind of "sensual" appeal.
"Ah..." Melusine awkwardly opened her cherry-like mouth, exploring a world she had never known.
"AAAHHH!!!" Haruka Kasugano shouted. This mouth... it's so small!
------
"Dearest, my brother sent me to deliver your catalyst~!" Sola entered the room excitedly, clutching a relic.
As she pushed the door open, a decadent atmosphere hit her. She saw Artoria alter in nothing but a camisole, her slender waist and long legs on full display. Melusine, meanwhile, was like a little kitten, clumsily licking the "lollipop" under Haruka Kasugano's guidance.
"Just like that... don't swallow too deep yet... use the tip first... like this... let me adapt first, your mouth is too tiny."
"Mmm~!" Melusine let out a soft sound, kneeling by Haruka Kasugano's lap and tilting her head, her big eyes full of focus as if she were trying to memorize every detail.
Sola stood there, stunned. "Dearest... how can you let the little sister do such a thing..."
"Little sister? She's a Heroic Spirit; she's hundreds of years older than your father. She's just petite," Haruka Kasugano laughed.
"Ah... she's so cute I keep forgetting that..." Sola said, half-laughing, half-sighing.
Sola carefully placed the fragment of the Round Table on the nightstand. Then, she began to slowly shed her own clothes, showcasing her perfect figure. Among the women present, she was the most curvaceous and had the longest legs.
She crawled onto the bed like an elegant cat, approaching the shimmering Melusine. She wrapped her arms around Melusine's soft frame from behind, feeling her warmth.
"Sister... no, I'll call you little sister," Sola smiled tenderly. "You're doing it wrong. Let me teach you. You need to focus more on the coordination between the lips and the 'spirit snake.'"
"Let me demonstrate first."
