Axel had just teleported to the prison dimension for Miguel to pick him up, and when he arrived, Miguel immediately said to him, "Axel, thank you for offering to help us. We don't usually accept outsiders on our team, but in this case, we're glad you're here."
Miguel then added, "There are a few rules you have to follow, though."
When Axel nodded, Miguel continued, "In reality, there is only one rule: you must obey my orders at all times, even if I order you all to retreat. Don't hesitate for a moment and teleport yourself back here with my men and wait for further orders. Is that understood?"
Axel nodded again, and Miguel then told him with a smile, "As for your powers, you can use them as you wish. The force field I placed around us is strong enough to completely mask our energy signatures. Even if a Knight of Darkness is on the other side of this impenetrable barrier, he won't be able to detect us."
