Chapter 139: Here It Comes

**Heroic Spirit Summoning** is a type of summoning ritual.

A summoning ritual doesn't require a grand ceremony; as long as the steps are correct, the summoning of a Heroic Spirit can begin.

Medea had long prepared the magic circle. She planned to use her role as **Caster** to perform an irregular summoning. Caster, the magus. Although she hadn't been chosen by the Holy Grail as a participant in the Holy Grail War, her current status as a **Servant** was deeply connected to the Greater Grail. She could exploit this connection to "trick" the Greater Grail into believing she was one of the participants.

A fundamental principle of magecraft is "deception," or rather, "disguise" and "alteration."

Conceptually, Medea was originally just a "Servant," but now she had added the attribute of "Master" to herself. Thus, Medea possessed both the attributes of "Servant" and "Master."

As a "Servant," Medea had her own "Master." But as a "Master," she lacked a "Servant" of her own. This created the possibility for an irregular summoning.

Medea explained it in the simplest terms, and after receiving this information, Li Mo pondered it.

"Miss Medea, I understand what you mean. In other words, at this moment, the Greater Grail sees the two of us as three people," Li Mo said.

"That's not entirely accurate, Master, but it's close enough," Medea replied.

She didn't elaborate further. The process involved too much **mystery**, and explaining it would be troublesome given her Master's current level of knowledge in mysticism.

While the concept seemed simple, the actual act of "deceiving" the Greater Grail into recognizing Medea as a "Master" was extremely difficult. Even for Medea, a renowned magus from the Age of Gods, it required significant effort.

In the depths of the cave, dim lights fueled by magical energy flickered. A magic circle drawn with chicken blood as pigment lay before them. Medea waited for the optimal moment to begin.

Li Mo stood beside Medea. The "Master" attribute Medea was borrowing came from him, so he couldn't leave during the summoning ritual.

Medea's operations were beyond Li Mo's comprehension. His earlier understanding was already the limit of his knowledge. The actual process was far more complex.

The **mystery** of concealment was difficult to learn. From a certain perspective, the talent of **Lord El-Melloi II** was truly terrifying—he could unravel the mysteries of others just by "seeing" them.

The time had come!

Medea began her incantation. For a magus from the Age of Gods, most spells could be executed with a simple command, without the need for incantations. However, the complexity of a Heroic Spirit summoning far exceeded that of ordinary magecraft.

Yet, Li Mo couldn't make out a single syllable of Medea's chant. It was blurred and rapid.

**「High-Speed Divine Words」**

When Li Mo had formed his contract with Medea, he had learned about her various attributes, including her skill, **High-Speed Divine Words**.

In games, this skill was represented as a charge, allowing the use of a Noble Phantasm in a single turn. In reality, **High-Speed Divine Words** compressed the time required for incantations to an extreme degree.

But…

The chant for summoning a Heroic Spirit was already brief. Did Miss Medea really need to use **High-Speed Divine Words**?

In an instant, the magic circle on the ground began to glow. The flow of air became chaotic, and the Mana from the greater source was affected.

A portion of the data from the **Throne of Heroes** manifested in this place, and magical energy formed a physical body. The spiritual foundation of **Assassin** slowly took shape.

Li Mo raised an eyebrow. Even though he couldn't yet see the full appearance of this Servant, he sensed something unusual.

The **Authority of the Beast** within him was stirring, as if it recognized the presence before him as a kindred spirit… No, that wasn't quite right. It was more like the Servant before him was a more suitable vessel for the **Authority of the Beast**. Like water flowing downhill, the **Authority of the Beast** wanted to transfer itself.

The origin of this skill was **Beast**, the Evils of Humanity. Could it be…?

Li Mo's mind raced with possibilities. He wondered if this irregular summoning had not brought forth **Sasaki Kojirou**, but rather… a Heroic Spirit who had once been a **Beast**?

There were quite a few such Heroic Spirits: **Kiara Sessyoin**, **Kama**, and others… all of whom had appeared in Chaldea's summoning chamber.

Before Li Mo could think further, the chaotic flow of magical energy stabilized, and the figure of the Servant appeared at the center of the magic circle.

A sleek black bodysuit accentuated her perfect curves, with glimpses of pale skin visible on her thighs. Contrasting with the black and white was a touch of pink—a fluffy pink tail, short pink hair, and pink ears.

Her golden eyes peered through glasses, and a faint, alluring smile played on her lips.

"Thank you very much for summoning me this time♡ Infiltration, production, negotiation, sales—I am **Tamamo-no-Mae·Koyanskaya·Light**, the representative of NFF Services, here to fulfill all your human needs!"

**Assassin**, **Koyanskaya of Light**.

Medea's face was filled with confusion. In her knowledge of historical heroes, there was no record of this Servant. Had she been uninformed?

Then, she noticed the amused expression on her Master's face.

"**Beast IV: Lost**, Koyanskaya?"

The Evil of Humanity, **Koyanskaya**.

A being born from the concept of the suffering and death of creatures during the **Tunguska Event**.

"Oh? Master's Master? I am indeed an Evil of Humanity, and you're absolutely right about that. But that doesn't stop me, the all-purpose beauty secretary-type bunny from the future, from serving you as Assassin!"

**Koyanskaya**.

No, **Koyanskaya of Light**.

Even with Li Mo's limited knowledge of mysticism, he could sense that she was merely a Servant, a manifestation of the **Throne of Heroes** in this world.

"Master?" Medea asked.

Li Mo said, "It's fine. I think I know what the catalyst was. My **Authority of the Beast**, right?"

A catalyst is used to summon a Heroic Spirit through a vague connection. Medea's "Master" attribute was borrowed from Li Mo, meaning she carried some of his essence.

But that alone wasn't enough. Koyanskaya's situation was special. She wasn't human but a amalgamation of the damage humans inflicted on nature and the loss of animal life. Her original self wasn't dead, so she couldn't normally be summoned as a Heroic Spirit.

However, Li Mo and Medea were exploiting a bug in the Greater Grail's system. This act bypassed the Grail's restrictions, expanding the "range" of the summoning ritual.

"That's exactly right, Master's Master. You and I share the same potential—the potential to become a **Beast**," the beauty secretary-type bunny said with a smile.
