Izen understood that Rem made more sense. Since Gabriel was so determined to enter, they could only stop him by force which meant establishing a bad relationship with the Holy Church of Light which was already known to be arrogant.
However.still, deep inside, he had a feeling that he couldn't allow Gabriel to enter the first floor of the Tower. It was a very strong feeling as well.
He chased after Gabriel inside the Tower of Challenges.
Gabriel seemed completely ignorant to the others. It was as if he wasn't in any hurry. He was just observing the surroundings like it was his first time here.
"This place is so beautiful. Nothing less expected from an ancient structure!" He exclaimed, ensuring that everyone heard it.
"Holy Lord, as I said before, you can't enter!" Izen appeared before Gabriel. Without the crystal, Gabriel couldn't enter in any case, so he didn't worry. He just had to send Gabriel back first.
