-42- A familiar that protect it's master

"Boom... boom boom..."

The sound of falling debris echoed continuously in the collapsing pit.

Olga Marie stared blankly at the scene, watching Mash fall into it, and then watched the collapsing pit bury her, her face turning pale.

"Mash!"

After a long time, Olga Marie finally reacted and frantically ran out of the building towards the collapsed pit.

"Fou! Fou!"

Fou also seemed to be relentless, running to the edge of the collapsed pit, calling for its master.

"Mash! Mash!"

Standing in front of the smoke-filled pit, Olga Marie kept shouting.

Naturally, there was no one to respond to her calls.

"Mash..."

At that moment, Olga Marie sat down on the ground, her expression showing a sense of numbness.

Her heart was completely enveloped in despair.

"Fou!"

Fou seemed as if it hadn't given up hope yet. Unable to find Mash after seeing the pit filled, it turned around and ran in another direction.

That direction was where the thrown-off Rozen was.

However, Olga Marie didn't follow Fou's lead to search for Rozen.

Because Olga Marie knew that with Rozen's physique, which was even weaker than an average person, there was no way he could survive after taking Berserker's direct blow.

"What do I do... what do I do..."

Faced with this situation, the director of Chaldea completely lost her composure, revealing her vulnerable side.

At this moment, Olga Marie was just an ordinary girl.

However, just then...

"Yo, were you looking for this little girl?"

Under a somewhat unrestrained laughter, Olga Marie jumped in surprise, like a startled rabbit.

But in the next second, she let out a joyful cry.

"Mash!"

Mash, who should have fallen into the ground with Berserker, was actually held up by a wise looking magician and brought down from the air.

"You really made me worried. If I hadn't come in time, you would have been done for, little girl."

Saying this, the Caster let out a hearty laugh.

"Who are you!?"

Olga Marie immediately questioned the stranger.

The Caster didn't hide anything.

"I am Servant of the Cater class. Well, as long as I'm not your enemy, you don't need to be too guarded against me."

With that said, Caster put Mash down.

But Mash's condition wasn't very good; covered in mud, she looked quite disheveled, with tear stains on her face, looking pitiful.

Upon landing on the ground, Mash immediately ran in the direction where Fou had just gone.

"Senpai! Senpai!"

"Wait! Mash!"

Olga Marie called out to Mash, then glared at Caster, being cautious of this sudden Servant, while approaching the direction Mash had run off to.

"It seems like I'm not well-liked, huh?"

Caster shrugged, showing no signs of being bothered by the situation, and with a relaxed and comfortable expression, he followed the others' footsteps.

Not long after, they arrived at the ruins where Mash was.

"Fou! Fouu!"

Fou called towards the ruins.

This scene was very similar to the one where Chaldea's control room exploded and Rozen found Mash, except this time, Fou was calling towards the buried Rozen.

But unlike the near-death Mash from before, this time when everyone arrived, they found something that made them all stunned.

The reason was simple.

In the ruins, it wasn't a mangled human body as they imagined; instead, there was a giant seashell buried there.

"Crack... crack, crack..."

There was a very obvious fierce mark on the shell, causing it to slowly crack, turning into pieces.

Inside the cracked shell, a pale-faced Rozen was lying.

"Senpai!"

Mash was both shocked and delighted.

"You... you're not dead?"

Olga Marie was also pleasantly surprised.

"Hoho..."

Even Caster was impressed by this.

"So that's how it is. You summoned a defensive Familiar in advance, just in case, didn't you?"

That is correct.

Before the battle began, as a precaution, Rozen had already summoned this familiar to protect himself.

--- "Giant Shell Summoning."

This was the last type of intermediate familiar magic that Rozen had learned.

It could summon a highly defensive shell to swallow the summoner and protect them when under attack.

Before the battle started, as a precaution, Rozen summoned it and hid it underground for any unexpected situations.

This action ultimately saved Rozen's life.

When faced with Berserker's fatal blow, the massive shell that was ready under his feet emerged, swallowing Rozen and providing protection.

In other words, Berserker's attack hit this sturdy shell instead of Rozen.

However, even witnessing the shell being slowly crushed, Rozen couldn't shake off the fear.

"Just a single strike, and it shattered the shell. Truly an undeniable monster..."

You see, the shell summoned by Rozen, although not as strong as Mash's shield, was enough to surpass the majority of higher-level familiars in terms of defense.

Having no combat abilities nor any other capabilities, this familiar solely existed to protect its master, and its high defense gave Rozen some confidence.

But now, witnessing the shell barely enduring a single attack, Rozen could only force a bitter smile.

"Can such a monster really be defeated?"

That question wasn't answered by anyone else but Caster.

"Don't worry, you did indeed defeat Berserker. The girl's final blow shattered his core."

Caster grinned, speaking confidently.

"Of course, you only killed him once. If it wasn't for Saber defeating him earlier, depleting his Noble Phantasms, you wouldn't have had a chance of winning against him."

These words carried a deeper meaning, catching the attention of many present.

"Killed him once?"

Olga Marie was puzzled.

"Saber defeated him earlier?"

Mash, who helped Rozen out of the shell, was also taken aback.

"Depleted his Noble Phantasms?"

Rozen furrowed his brows.

Seeing this, Caster gazed at the group.

"This is not the place to talk. Let's move to a safer location."

With that statement, the group left the battlefield and walked towards a hidden shelter where they could rest and discuss.
