You walk through the city where you live, Karakura City. Your family had sent you to the store to buy dinner, what you wouldn't expect would be to see a big monster attack your family, your house was a mess. However, a mysterious swordswoman who dressed in dark clothes protected them with soul and sword.

This swordswoman was very injured, her shoulder seemed to be completely bitten. So, you quickly approach while she talks to you.

"That...spiritual pressure...may it be?..."

Just when they were trying to talk, the monster approached, so that swordswoman would have no other option to tell you the following.

"I don't have the energy to continue, but maybe you can save us. Do you want to save your family? Go ahead, touch my Zanpakuto."

In the light contact, a light blue glow would invade the place, when it dissipated, you would have the same clothes that she had and a katana. Now it was just you and that monster, let's fight!
