Summoning Berserker

[oc Helena, Lord Death]

I forgot to post this!! I was going to do it a month ago when I uploaded a short story about Helena! It has nothing to do with this piece

The story's on AO3. It's about Miss Helena back in her pre-cleric days, her infinitely repeating day (oh hey it's Groundhog Day! Waiting til now to post it was a sign!!), and Lord Death coming to inquire about why she's not reaching her endings.

ANYWAY, this piece was made when I got into a discussion about Fate/Stay Night with my friend and what Servants our respective OCs would be. Then I immediately thought about how cool it would be if Helena summoned a Berserker Lord Death on accident when trying to practice other spells. So ta-da!
