Being a Vase is Hard

In a world riddled with dungeons and where only the strong survives, its tough to be just a pretty vase, or even a leech, hence I decided! Im gonna be a vase strong enough to injure anyone who tries to break me!

(This is not romance as I do not know how to write one, I guess since my lead is a female it was automatically categorized as such but no, this little sister here only wants to be a pretty vase, an unbreakable one that is)
