Epic, looks sort of like he's fighting tohsaka rin.

From the thumbnail i thought this was from Fate/stay night.

Maybe Archerko?

The pixiv tags don't include the character, but they do include "TYPE-MOON", "宝具 (Noble Phantasm), and "英霊 (Epic Spirit)". So, probably Archer/Archerko, yeah.

but she dont got twin tails

Still doesn't explain the female Archer, though. But what the hell, this picture is perfect as is. Santa is pure A-Class.

twin tail = Tohsaka?

No idea who that girl on the right is supposed to be. Only Santa is labeled in the pixiv tags, and the artist's comment is just a silly pun.

It might be Archerko, but the twintails kinda throw that off.

Saint Nicholas of Myra as Berserker? Epic.

Shouldn't Santa be more of a Rider-class?

Well, Santa ride a sleigh pulled by reindeers, so it may qualify him to be a Rider.

Unlimited cane works!

I am the Milk of my cookies
Jolly is my body, and snow is my blood
I have laughed over a thousand HoHoHo's!
Give either toys or Coal
I have withstood many nights delivering presents
Yet these hands will never receive anything
And as I pray, Unlimited Peppermint Works!!

UNLIMITED CHRISTMAS WORKS

Any Eirei can be forced into the Berserker class upon summoning.

Rin wearing ARCHER tier armor.

Santa Claus must be a Rider-class Heroic Spirit :v
