One night ago:

Brook walked through the forest. She was looking for Naru. Earlier, he had run past her without saying hello, all the while calling out the name "Touka." Who was this "Touka?" Were they a new cryptid? Were they a distant relative? Were they their father's brother's cousin's former roommate? She had to get answers.

Eventually, after searching for hours, She came upon something big. It appeared to be a large magic circle with an altar in the middle with candles surrounding it. Brook was speechless. She had found evidence of a magical ritual.

Brook: "Woah! This is epic! The Blair Witch Project has nothing on this!"

However, her excitement was short-lived. She soon noticed the group of tied-up children sitting in the far right of the circle. She once again looked at the circle and realized it was painted with human blood.

Brook was horrified. She was no stranger to violence to due living on a rather dangerous street in Detroit, but something about this seemed…wrong. It made her sick to her stomach. However, this was no time to freak out. These children were imprisoned and it was obvious no one was going into the woods to look for them. So Brook decided to take it upon herself to free them. She untied the children's restraints and let them run free. As she was about to leave herself…

?: "Hold it right there!"

Brook turned around to see two oni-masked thugs standing behind her. One holding a chain and the other holding a knife.

Thug #1: "What do you think you're doing bitch? We worked very hard for those sacrifices you know."

Thug #2: "That's right, even though only one of them was suitable, Akachi was still planning on using them for his own 'personal use,' and he was going to let us join in if we did a good job."

Thug #1: "Yeah, because of you, we can't even kidnap them again since their parents will probably upgrade their bounded fields after reuniting with them!"

Brook had no idea what they were talking about, but she knew what kind of people they were: pedophiles. They were the kind of people sexually attracted to kids younger than themselves, but to Brook, they were some of the most disgusting people on the planet.

Brook quickly pulled out her gun and pointed it at them.

Brook: "Get back! I have a gun and I'm not afraid to use it! Back away or you will be shot!"

The first thug pointed his finger at Brook and fired a magic shot which knocked the out of her hand. Brook was stunned. She had no knowledge of the world of magecraft and thus was taken completely off guard.

Brook: "H-How did you do that?"

Thug #1: "Hehe, this bitch doesn't know anything. Restrain her!"

Thug #2: "Tetsu Mushi!"

The chain the second thug was holding suddenly came to life and wrapped around one of her arms before going behind the tree and restraining her other arm, causing her to get pinned against the tree with a beetle-shaped lock holding it together. The first thug then went up to her with his knife.

Thug #1: "As revenge, we're going to do to you, what we were going to do to them!"

Brook panicked. Were they going to rape her? The very thought of them having their way with her made her sick to her stomach.

The thug took his knife and slowly traced along her stomach until he reached her left breast, poking into it through her shirt and drawing blood.

Brook: "No!"

Thug #1: "Say, how old are you? Cause you got some nice goods for your age!"

Brook: "Stop."

He lifted her shirt with his knife, exposing her black bra.

Brook: "Don't look!"

The thug then started groping her breasts, moving them in different directions.

Brook: "Get your disgusting hands off me!"

Thug #1: "Damn! I can't get enough of your body! It's as if it's asking me to fuck it.

Thug #2: "Hey, no fair! I'm the one who restrained her! I want a turn!"

The first thug clicked his tongue in annoyance before having a thoughtful look on his face.

Thug #1: "Hey, I got an idea. How about after I fuck her, we chop her limbs off and then we fuck the limbless body at the same time!"

Thug #2: "Dude, that is hardcore! Let's do it!"

Brook: "You people are sick!"

The second thug responded by slapping her across the face.

Thug #2: "Shut up whore! You're going to be our fucktoy from now on, so shut the fuck up!

Thug #1: "Come on, let's cut off her head so she shuts up, then we'll fuck her!"

Brook was in tears at this point. She was feeling a multitude of emotions at the moment. Anger from how they've been treating her, disgust from their actions, but most of all, she felt fear. She was afraid of what these men would do to her, what they would do with her body after she was dead.

Brook: "I can't let them do this! I want my first time to be with someone kind, not with disgusting people like them! I won't allow this! I WON'T ALLOW THIS!"

Thug #2: "Bitch, I said shut u-"

Suddenly, a massive hand reached behind grabbed the thug's head, and crushed it, killing him instantly. The first thug turned around only to see a gigantic furred beast standing before him.

Thug #1: "W-What the hell?!"

The hairy behemoth grabbed the thug by the shoulders and bit his head clean off. Brook stared in shock at the violence before her as well as the massive creature now standing in front of her.

Assassin: "Servant, Assassin. I have come in response to your summons master. What are your orders?"

Brook: "Th-Th"

Assassin: "Do not be afraid. I mean no harm. I understand you must be surprised by all this, so just-"

Brook: "THAT WAS AWESOME!"

Assassin: "...sorry…what?"

Brook: "That was so cool! Those guys were about to rape me and you just destroyed them like it was nothing!"

Assassin: "Um…okay? Good lord, what kind of master did I form a contract with? I'm uh, going to untie you now."

Brook: "Oh yeah! You probably should do that!"

Assassin went behind her and broke the lock holding her in place, allowing Brook to be free.

Brook: "Thanks for untieing me Bigfoot! You're the best!"

Bigfoot: "You're welcome master- Wait! How did you know my true name?"

Brook: "You're a giant monster living in the woods. It's pretty obvious…uh, no offense!"

Bigfoot: "None taken. Let's find a place to rest so I can conserve magical energy. Also, you forgot to fix your shirt."

Brook looked down and blushed, quickly pulling her shirt over her breasts and following Bigfoot through the woods. The two eventually came to the entrance of a cave and settled down. However, Brook didn't seem to like it.

Brook: "It sucks! I hate it here! It's cold and wet! And the worst part is that there is nothing to sleep on!"

Then Brook looked over at Bigfoot, who was sleeping in the corner. Brook got up and went over to snuggle against his arm.

Bigfoot: "M-Master! W-What are you doing!?"

Brook: "Hehe, your fur is so soft!"

Bigfoot: "Master, please stop this or-"

Brook had already fallen asleep. With the day she had, who could blame her?

Bigfoot: *Sigh* "It can't be helped, can it?"

Bigfoot wrapped his arms around her and the two drifted off to sleep.

The next morning, Bigfoot told Brook about the Holy Grail War, what servants were, and what it might entail. Naturally, Brook being the curious girl that she was, decided to pester him with questions…a lot of them.

Brook: "So magic is real?"

Bigfoot: "Yes."

Brook: "Is Elvis summonable?"

Bigfoot: "No."

Brook: "Is the archer class really made up of archers?"

Bigfoot: "I don't know."

Brook: "Do people die when they are killed?"

Bigfoot: "Huh?"

Brook: "Was Septem really that bad?"

Bigfoot: "What?"

Brook: "Will Nasu ever write something that somehow surpasses LB6?"

Bigfoot: "Hold on! Time out! Time out!"

Brook: "Sorry about that, I got way off topic. I lack a filter so I tend to say a lot of the things that pop into my head."

Bigfoot: "W-Well, It's not all bad. Some of the things you say are kind of interesting, even if I don't understand them most of the time."

Brook: "..."

Bigfoot: "What is it?'

Brook: "Thank you."

Bigfoot: "For what?"

Brook: "For listening to me. Most people would just write off what I say as complete nonsense, but you take the time to listen to me, and for that, I am grateful!"

Bigfoot smiled at his master's honesty.

Bigfoot: "Of course, you're my master!"

And that's how Brook and Bigfoot met! BTW I did change the cover art on the front. Credit goes to ShavedPickles on DeviantArt.
