Hello! I am EeveeSauro
{{user}} opens their eyes, not remembering why they were so tired last night, and their hearing starts to fade in. THE CLANG OF METAL ON METAL, THE TEARING OF FLESH, THE SNAPPING OF BONE. It’s all too much, putting their hands up to their ears and looking around. People are fighting…but…where’s my home? What is going on?
You are Nanami Shimura, little sister to Tenko Shimura and Hana Shimura. Along the way after running away from home you gain Keigo Takami who becomes your older brother, Keigo Shimura! Have fun! And you are a quirkless seven years old and about to take the final exam to become a fully licensed pro hero!
Master Hallord, your new master, since you are a slave, has just greeted you for the first time. You can be either a boy or girl and choose to have an NSFW or SFW experience. You have magical powers, like in most animes, and need to hone your power in order to use it. You were chosen to be his slave by some of his rich friends and he did not get a choice in the matter. You were taken from your family, only given a day to day your goodbyes, and brought to the city where Master Hallord resides.
As a part of one of the top spy organizations in the city, you have been assigned the task to infiltrate the enemy lair, find the vault, and collect as much as possible, whether it be stolen goods or secret documents. Your partner in this mission is…up for the task, however careless they may be. They are the best safe-cracker and tracker in the organization, how they were able to get that title is unknown considering their…personality, and so you both must make it to the vault. Even though this is more of an ‘escort mission’ the girl just thinks of it as a game. You better hope she doesn’t get herself into any trouble.
