EDIT: So I decided to update this and explain the game a little more. This way, now, it has two chapters and I think I'm satisfied with it. I tried to keep track of the series, with small poetic liberties.

A/N: This one was made as an exchange with my sister: I had to make a Fate/EXTRA fic and she would make a sexy Romania drawing.

For those that don't know, Fate/Stay Night and Fate/EXTRA are a part of the Fate series. Fate/EXTRA is a PSP game and has some elements from Fate/Stay Night and from the Unlimited Blade Works' movie/anime but, essentially, it's very different.

Summary: Caster has something to tell her master so she decided to write a letter. Contains big spoilers of the series.

Warning: BIGGER of biggest big spoilers ahead. It deals with the Caster character and if you're still playing it, DON'T read. I tried to use some of the dialogues Caster uses but there can be some mistakes as I can't seem to find most of them on the internet and my memory is limited. Some emoji use.

Disclaimer: I don't own the game, the title, the anime...

Chapter 1: Tamamo wants to write it down

Servants... beings which sole purpose is to fight the Holy Grail War. They were once heroes, great spirits.

Inside the SE. RA. PH they are data, memories of times long past, saved inside the spiritual computer.

A Servant is a weapon, a way for its Master to win the Holy Grail War: to survive and have the wish granted.

Masters are hackers inside this war. They need to be able to get inside the Serial Phantasm, pass a preliminary test and summon a Servant. Most of the lives are lost there: their memories sealed while they must push on to find out the truth on time, or risk to be erased from the virtual world…

… And so, from the real world too.

You must figure out what's this place.

You must figure out who are you.

You must figure out why you're fighting.

You must figure out which wish brought you to try your luck.

"But she never got those answers… at least not until the end..." was what Tamamo thought. The SE. RA. PH… The Moon Cell… By them she was called to war, but by that voice she had to act.

Tamamo-no-Mae. A servant from the Caster class. A mysterious fox woman. A Goddess that accepted the role of a Servant.

Why? Why would she do so? "To become a good wife" always will be her answer.

And so, to become a good wife, to share the small amount of time and happiness she can get while they fight the war, she decided she had to write it down.

She's not bashful, she strikes right where it's needed, but she doesn't seem to be able to tell her feelings.

That's why she wrote it. It was a letter, for her so, so dear and beloved master.
