"Are you sure you want to go alone?"
"I must. This is a matter that began with me, so it must end with me as well."
"... I understand, however, I'm going to come with you. There's still a possibility you will–"
"No, you have something better to do, don't you? There should be roughly 500 Lords remaining."
"That doesn't matter. You know they won't have any impact on my power."
"Maybe not, but you are in need of experience more than power. Now that you have awakened your true self, you must become equipped with using your strengths to their full potential."
"I don't like how right you are."
"Yet, right I am regardless."
"Haa, I get it. But when I finish, I'm coming. Don't think you can stop me."
"Mm, it is nice to have a friend like you."
"Friend, I'm honored."
"You should be."
The last conversation between Tiamat and Iris went something along those lines.
