FGO System in the Type-Moon World

How did this happen?

Originally, this body had been chosen by the Grail as a Master.

He had been granted a Command Spell—

But thanks to the system, that powerful magic transformed into Chaldea's Mystic Code Command Spell, essentially removing him from the Grail's roster.

Thus, the Holy Grail mistakenly assumed that Reiji—a worthy candidate—had no Command Spells.

And since Ryuunosuke's slot was now empty—

The Grail simply granted Reiji a second Command Spell.

The result?

The system now had control over another Master's slot.

And Reiji's maximum Command Spells increased to six.

Just as he was processing this, the system spoke once again.

[Congratulations, Host, on acquiring a Command Spell]

[Reward: One Free Standard Servant Summon]

[Note: A standard summon does not count as a system-linked Servant. If you wish to bind them to the system, spend 3 Saint Quartz to upgrade them.]

Reiji hesitated.

His mana recovery speed was ridiculously fast, but he still didn't know his total reserves.

Mystic Code: Chaldea had powerful abilities, but it directly drained mana for usage.

Adding another Servant to his roster might put him at a mana disadvantage.

As he was deep in thought, the door to his room swung open.

The one who entered—

Was Tamamo-no-Mae.

"Master, although I despise building workshops… I've created something close to one. Would you like to see it?"

Reiji met her gaze—

Then slowly nodded.

"Let's take a look."

The summon could wait.

Actually, he had another idea.

If he didn't want to personally handle another Servant's mana upkeep—

Couldn't he just transfer the Command Spell to Tamamo?

After all—

She was incredibly powerful, but her personality made her better suited for support rather than direct combat.

If she was participating in the Grail War, she would need another Servant to support her.

Berserker was powerful—but if he ever had to face an enemy like Iskandar, things might not be so simple.

Servant battles depended on compatibility.

Berserker could probably crush most Servants one-on-one.

But against Iskandar's Reality Marble, the outcome would be uncertain.

If he could summon one more Servant, their chances of victory would skyrocket.

Thinking this over, Reiji followed Tamamo outside.

Ryuudou Temple - Workshop Setup

Originally, the temple grounds had inhabitants.

But Tamamo cast a charm spell, temporarily sending them elsewhere.

For now, the temple belonged to them—

Just Reiji, Berserker, and Tamamo.

And in the temple courtyard, Tamamo had erected a stone altar.

On the platform, she placed a mirror adorned with blue edges and golden patterns.

Reiji recognized it immediately.

Tamamo's Noble Phantasm.

Sensing his confusion, Tamamo giggled and explained.

"Even though I hate making workshops, since it's Master's command, I did my best~!"

"This is my Noble Phantasm, already activated."

"Within the entire mountain's range, any ally I recognize—

—will have their mana upkeep reduced to zero."

"You can fight as much as you want without worry!"

Reiji froze.

Then—

A grin spread across his face.

"Now this… this is insane."

Without hesitation—

He activated the Attack Boost skill on himself.

As expected, Tamamo's Noble Phantasm worked differently from the system's mana recovery.

It seemed like something within this bounded space was substituting his mana consumption, allowing spells to be constructed as if they required no energy at all.

This discovery pleasantly surprised Reiji Souma.

"Tamamo, what if I wanted to summon another Servant? Could your Noble Phantasm sustain the mana cost?"

Tamamo-no-Mae's fox ears twitched, and she nodded seriously, before flashing a cheerful smile.

"Although little Tamamo dislikes fighting, if it's for you, my dear Master, then there's nothing I can't handle in terms of support!

After all… I am the all-capable, ever-loving wife! Tamamo, at your service!~"

Hearing this, Reiji's smile widened.

"Good. In that case, let's welcome a new member to the team."
