Shapeshifting and Healing

"I choose shapeshifting and healing!" you say.

"How unique" the kawaii anime waifu goddess says. Suddenly, she leans in for a kiss, her lips become enormous. You can see every detail as they become closer and more massive. You're sucked into the gravity of this kiss, and it pulls you into this cloudy mist. You emerge, fully clothed in fancy silk robes. As the mist fades, you see that you're in some kind of room with a shrine. Around you are many blue and purple skinned people. Directly in front of you is an old bearded man, wearing a very ornate hat and covered in jewelry.

"Divine spirit. I hereby bind you to first Prince Jun." he speaks, in a powerful, booming voice.

You see that a young man is behind him. He is a sickly pale, but wears the finest robes in the room.

Suddenly you feel a connection to him. You stumble and kneel to the ground.

"If he is harmed, you will face the same damage sevenfold. Your duty now is to protect the first Prince, and serve as his shield against this world."

"Very well" you say.

Jun, nervously approaches you. Behind him is a very well dressed woman, with similiar features. Her hairstyle is ornately fixed with gold pieces, and her robes feature elegant designs of peacocks.

"I am First Prince Jun of the Sentral Empire. My domain is all under heaven, from the Western wastes to the Northern seas. From the great Eastern Fortress and the Southern Vassals. It is an honour to meet you, divine spirit." He says.

You think of how you should respond. What are the manners in this world? Could you be beheaded if you respond the same way.

"Does the spirit speak?" A bearded, scarred man, clad in black armour shouts.
