"How crazy is he to be challenging all the participants, declaring the start of the climax battle?"
Wasn't everyone nervous about the conclusive battle?

He was basically saying, "Want to know where I am? Easy, I am here. Just come at me, you cowards."
While smiling, Reve faced Amice, "What do you want to do? I plan to answer his beckon. Other groups will do the same."
"Then we won't be any different."
"It will be dangerous." Reve eyed Amice. He was trying to tell her he wouldn't be able to protect them once the battle started.
"Don't worry. We are prepared for anything that might happen. All that we ask is that you assist us if it's within your power."
Avidanna said, "We can do that, at least."
The ring on her finger shined for a brief moment.
