I am Archer, a COSER who loves Berserkers. My Command Spells are written in red ink, and my Noble Phantasm is a plastic replica bought online, with a "buy three, get one free" deal, including shipping.

The ones who summoned me are the self-proclaimed strongest duo.

Wearing a set of Berserker armor, the COSER says:

"Master, I will serve you wholeheartedly, but don't lie to me, or I'll eat you alive, hahaha..."

"Oh, Saber, how can you be so rude? Mother, mother is doing this for your own good!"

"For the sake of treatment, for the sake of humanity, even if I become a demon, I will eliminate all pain!!"

"Power is surging forth... Realize it! Air conditioning!!"

"Aaaarrrttthhhuuurrr—!!!"

Everyone: ...

So, what exactly did those two strongest masters summon?
