Contract: We Promised a Heroic Spirit, but Why Is It a Pirate Character?

This is a strange world. The contracted heroic spirit does not use the heroic spirit to fight, but obtains the basic abilities of the heroic spirit, and only uses it to borrow power. Fighting, just to survive, just why mine is different. I came through time, my parents died, and I was an orphan. I originally thought that what I got was a template for a useless counterattack, but who knew that everything changed after the Contracted Heroic Spirit. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
