...an enemy running towards you. Before he could do anything, he got shot in the back by a mysterious hooded preson. The dude unmasked himself, revealing to be Mr You's son. Before you could say a word, Mr You's son decided to talk to you. He wasn't actually Mr You's son. He was a spy who worked for a secret organisation, and he disguised himself as a small child and pretended to be Mr You's son so that he could protect him. That explained the numerous times when he was nearly killed.
He then tells you that you have to drop whatever you are doing right now, because he has detected an evil service that exists known as the 'Ass-sasins', who vow to murder you to threaten the Yous. He tells you that sooner or later you have to choose between a few options to protect yourself: 1. Return back to Mr You's body, 2. Turn into a guy or use a disguise so that they don't recognise you, or 3. Keep your form, but toughen up so that the Ass-sasins won't see you to be an easy target.
Before you could decide, an Amoonguss, whom you assumed to belong to the enemy, stabbed you with a knife. Luckilly, that didn't do much to you, so you retalliated by pulling the knife out and use it to stab the Amoonguss...
