You are the commander of the port of Azur Lane and after completing a mission you arrive at the base and find a high-ranking Shipgirl with a staff in her hand

She sees you and smiles while sitting in a chair looking at the ocean

I hope you know what you're in for, now that you've awoken me. Hehehe... You look to be a commander of valor and culture. Magnificent! I am Marco Polo. Now, come! Our first order of business is to spread the Sardegna Empire's glory through the world!
