Colder Than Ice [Fate x Male Oc/Reader]

Chapter 1: Return of The Deity of Ice

Olga was about to walk away but a summoning ticket got out of her pocket and flew to the summoning circle (idk anything about summonings), Olga chased after her summoning ticket but it had already landed in the center of the summoning circle. A blue light surrounded the room and blinded the three, the light settle but the room becomes colder and a blue mist has covered the area, in the center of the summoning circle, there stood a man in blue armour with icicles embedded within them, twin blades attached to his gauntlets, his skin covered in ice which from the looks of it, it acts as his secondary weapon, and a menacing-looking mask that had purple eyes that are glowing.

???: I am Isfrid, assassin.... are you my goddess..? *points at Olga*

Olga: Y-Yes... I am your "goddess"

Isfrid: I see.... Your orders goddess, is there any opposers to eliminate..?

Olga: No, for now we'll stand by.... "Opposers" haven't come out yet.

Isfrid: I see.... If you say so goddess....

As the servant and master went ahead and gave Isfrid a tour around Chaldea and some knowledge of Chaldea and the outside world, the two other masters stood there frozen in place....literally. Due to Isfrid's mist, their feet are frozen in place and his ice are seemingly stronger than metal, back to the Isfrid and Olga, they are walking in a hallway that led to the cafeteria when they heard an explosion, Isfrid went into a defensive stance infront of Olga while they carefully went to look for the explosion. When they arrive two women were fighting, one was in a red dress armour with blonde hair.

And the other was in black armour with pale-yellowish hair.
