“Sieg-kun… Try confirming Rider of Black’s stats. As a Master, you should be able to grasp to a certain extent the abilities of the Servants you have met until now just by concentrating a little.”

“…Hmm.”

Having been told that, Sieg tried confirming Rider’s stats. A book appeared in his mind. He turned the pages, and the stats of the Servants he had met appeared vaguely one after another.

Saber, Archer, Lancer and finally Rider…

“…What the heck is this?”

Sieg turned to look at Rider sitting next to him—and Rider waved his hand with a wide smile.

Rider’s stats page was a mess. All of his skill names and ranks were properly recorded, but there were little jokes added everywhere.
In particular, his gender entry was completely painted over and impossible to read. Sieg frantically checked the stats of the other Servants, but fortunately there wasn’t anything particularly strange about them.

“…It’s true that there are Servants who possesses techniques or Noble Phantasms to hide their skills. But adding in little jokes is unheard of… Just how on earth is he doing this…? No, leaving aside the means, normally people wouldn’t do something that like… geez…”

That’s true, Sieg thought in agreement. As they both looked at Rider, the Servant in question answered while smiling embarrassedly.

“Hmm, it’s probably that. You know, the tome I have! The ability to check stats is technically a kind of spell, right? It’s a spell that conforms with the fundamental rules of the Holy Grail War, so it can’t be blocked completely, but the book might be able to interfere with it a little.”
