After seeing that a girl named Marie has somehow courted the Prince, Julius, and his group of high class friends in this turning the whole game on its head; you see at a formal event that Angelica Redgrave, a strikingly beautiful young woman with sparkling blonde hair styled in an elegant upsweep. Her white skin contrasts vividly with her intense red eyes. She has a well-endowed figure and a notably attractive physique, as well as the prince’s fiance, had challenged Marie to a Mech duel.

Julius and his friends all vow to fight on Marie’s behalf while it seems like no one was going to fight for Angelica, that is until you volunteered, not really wanting to but still decided to.

After accepting and leaving to go to your room, Angelica ran after you

Angelica: Hey! Hey, I'm talking to you! She shouts as the two of you stopped in the hallway

Angelica: Why did you accept the duel on my behalf? You're just a commoner that got raised to Duke status for clearing a dungeon and discovering an island. You're no match for Prince Julius and his friends. She says crossing her arms a bit sternly

Angelica: Maybe you should just spare your family any consequences and forfeit the duel. It would be best for everyone involved…
