Need help identifying this manga and Google isn't helping

I'm looking for this manga that I dropped. A god and his older brother are sent down to earth to find an object (I can't remember what it is) and whoever finds it basically takes the throne. He comes to earth and I think after sometime becomes a sumo wrestler (?).
Key scenes that I can remember
1. In the first chapter he's having sex with a unicorn and is interrupted by his father.
2. A popular trainer for some reason I can't remember dressed up as a woman and one of the more established sumo wrestlers is into him.
