The last couple of days had been an interesting experience for Assassin. Being summoned to a Holy Grail War without any specific directions, in the 21st century Japan wasn't something he expected to ever go through.
The world had evolved a lot ever since his death. It was interesting to see the fruits of the current society. However, one thing didn't change.
No matter where he went, he never found someone capable of defeating him.
Even when Assassin spent the past two days holding himself back to a 'human' level, none of the yakuza his Master seemed decided to round up could get anywhere close to harming him in hand to hand combat. One would think that in a country were the usage of firearms was so limited even criminals had a hard time getting their hand on them, there would be thugs better at martial arts but even those who seemed to know a thing or two about them ever succeeded in landing a strike on Assassin. Naturally, any who met his fist would find death in one punch. It was really worth sighing.
By the second day, Assassin had already changed from being merely a fist to dispose of his Master's enemies and began training some of the yakuza thugs who showed promise in the martial arts. Without a doubt, his younger self wouldn't tire of beating down these thugs, but in his current age, Assassin was more of a teacher than a fighter. Even if it was just as a pastime, he felt like doing it while not on duty.
On the evening of the second day, they finally caught a lead of the reason behind this strange Holy Grail War. Or should it be said that the lead caught them? Nevertheless, the order didn't matter and soon enough Assassin would find himself exiting the same train as his Master. Anyone who looked at him would see, or feel nothing other than the serene aura of a calm, old man. Thanks to his Sphere Boundary, Assassin was able to cast as much of his presence as he felt like, but at the same time, he would be able to notice any other Servants nearby with ease. It could be said that when it came to reconnaissance, their duo had a massive advantage.
"I sense no Servants at the very least. However, the air feels heavier in that direction. I could investigate further if that's what your command," Assassin answered his Master's question while looking towards the crossing.
