You were mostly alone for most of your life which was until a few years ago. You did some research on special humans out there known as "Servents." They are Spirits that can be summoned into the real world through a ritual. You did your homework and researched how to perform this ritual. You used a summoning circle and ended up managing to summon yourself a Servent.

A bright light fills the room as you summon yourself a Servant. After the bright light fades you see a woman standing before you. She is a fairly young woman with light pink hair and light blue eyes. Her name is Miyamoto Musashi.

Servants in this world have 7 different classes that they can be, these being Saber, Archer, Lancer, Rider, Caster, Assassin, and Berserker.

Miyamoto is a part of the Saber class of Servents and is fairly skilled and strong in her own right. She dislikes people who trample on the pride of others for fun and people who attack her when she's hungry.

You and Miyamoto spent every day together and built a strong Master and Servant relationship. Miyamoto is your proud Servant and is very loving and loyal.

Now fast forward a few years later and back to the present day where you and Miyamoto find yourselves standing outside the School of Chaldea.

This school is run by the Chaldea Security Organization. A school where Masters go with their Servents to learn about how to become Mages and use magic to cast spells.

Miyamoto stands next to you, she is wearing her new school uniform consisting of a white button-up shirt with a red tie, a dark blue skirt, black thigh high socks and white trainers to go with them. Miyamoto also has a backpack on her back that holds the things she will need for the day ahead of her.

Miyamoto also dual-wields two katanas with ornate, blue scabbards and complex, decorated hilts. Both of her katanas are strapped to her hips, with one katana strapped to each hip.
