The atmosphere inside the venue changed abruptly.
It was as if mentioning the Old Man of the Mountain was a taboo for the female assassin.
Grim—this word best described the scene.
However, no words were needed between the two sides.
Knowing that they were both Servants in this Holy Grail War, their only relationship would be as enemies.
The murderous female assassin moved around the stage at high speed.
The man stood still, but his eyes moved just as quickly, encompassing the mysterious woman's movements.
In passing, he glanced at Kayneth.
With a mythical hellhound protecting his Master, the assassin had no way to attack.
He could fight the assassin to his heart's content here.
However, having just awakened and smelling the scent of his homeland, the man was filled with nostalgia and excitement.
Suddenly, as if stirring up a bloody storm!
An unusually long arm emerged from a dark corner, stabbing towards the center of the man's back.
Just like how she slaughtered many mages in the city.
This was the hand of Satan seeking a heart.
Its prototype was her imitation of Hassan of the Cursed Arm from the successive generations of Hassan, a unique skill belonging only to the female assassin.
Now, this ability has evolved into her Noble Phantasm.
Unfortunately, the arm failed to touch the man's body.
An arrow released from somewhere deflected the woman's arm.
"…!"
The female assassin's eyes widened slightly in surprise.
This attack came completely from her blind spot.
Moreover, judging from the man's composed appearance, it seemed he had experience fighting assassins of this kind.
"Hahaha, don't be surprised. But, I must say, your cult's assassins are truly extraordinary. I haven't seen many with such beautiful skills as yours. Even Hassan, who has obtained the title of Old Man of the Mountain, is very different from you."
The man, resembling a nobleman, drew the sword from his waist.
It was an extravagantly designed sword.
"…"
The man's words made the female assassin pause.
The topic was brought up again about the Old Man of the Mountain.
This time, a brief moment of sadness flashed in her eyes, before turning resolute and firm.
Comparing her to the revered leader.
Undoubtedly, this was impure.
As the man said, she was not qualified to be compared to the successive Old Men of the Mountain.
At the same time, the man still wore a smile.
His act of drawing his sword seemed to acknowledge the female assassin's skills, intending to use his full strength here.
Accompanied by that powerful shout.
A light like the breath of a star dispelled all darkness.
"[Excalibur]——!!"
The light headed towards the female assassin's location.
Which was towards the ceiling.
The man's magical-infused sword shot out a stream of lightning-like light, rushing straight towards the target.
Their battle had lasted less than a minute.
Kayneth, who was watching, didn't even have a chance to recover.
He only heard the rumbling sound.
Even the Moon Spirit Altar could not maintain its magical stability in the face of that raging breath.
He fell to the ground, looking up at the vanished ceiling.
And the starry night sky.
That breath of a star stirred up Kayneth's distant memories, he remembered being impressed by this.
However, the memory was somewhat vague.
He was certain that he knew the identity of the Servant before him.
Moreover, this Servant was someone he was familiar with.
"I ask, are you my Master—?"
Before Kayneth could come up with an answer.
The words reached his ears along with the biting cold wind.
It was as if time had frozen.
Under the shimmering moonlight and starry sky, the man holding the holy sword gazed at Kayneth, who was lying on the ground.
It was like a solemn historical painting.
Of course, Kayneth was an extremely mature and excellent Master, so he would naturally not say anything other than acceptance.
Unsurprisingly, the man and Kayneth formed a contract.
Kayneth became his Master.
"Rest assured, Master. It seems no civilians were caught up in this, but it also seems the thief has escaped… Hmm, to be able to escape from me, quite the remarkable fellow."
The man glanced at the remains of the mages on the ground.
He shrugged without being particularly affected.
It seemed that neither the female assassin nor the mages were truly worthy of his attention…
"Speaking of which, what's with that hellhound! It feels so powerful! Has my Britan become so strong in later generations?! Ah… how wonderful, very wonderful! Hmm, hmm!"
The man nodded repeatedly, very satisfied.
Although he looked young and handsome like a noble young master, he was also strangely like an old elder looking at his descendants.
The joy and elation in his eyes were not concealed.
The hellhound had disappeared.
Kayneth didn't know where it had gone, nor did he know if the hellhound could only manifest once.
But, he didn't feel any regret.
If this Holy Grail War required him to rely on the King in every situation, then Kayneth might as well kill himself.
He must not let the King expend effort to take care of him.
He must not hold back that King.
What he wanted to offer Britan was supreme glory, not the shame of constantly needing to be protected!
"Oh dear, look at me being so anxious, I haven't asked the most important question yet, let's start with this… Master, are you British?"
The man laughed rashly.
His smile was very sincere, eager to get an answer.
"This…"
Just as Kayneth was about to answer, a man's roar came from one of the entrances of the theater.
"Don't move! Put your hands behind your head and lie on the ground! Slowly!"
Unlike the mages participating in the Holy Grail War.
The identity of the newcomers could be identified at a glance.
More than one person, they were wearing uniform clothing—that is, police uniforms, and aiming stun guns used to suppress rioters at the two of them.
That's right, the police regarded this as a crime scene.
The blurred mass of scarlet flesh on the ground, the magical circle stained with blood, and the opera house suspected of being a bomb terrorist attack.
Kayneth and the man in armor in the center of the scene were obviously not normal people.
"I am arresting you on suspicion of illegal intrusion and carrying out a terrorist attack that damaged the building. Listen carefully, you have the right to remain silent…"
There were more than a dozen policemen who came.
A policeman came to the two of them with handcuffs. Kayneth couldn't use suggestion here.
