When you enter Phantom's Gate. You noticed the environment, is pretty dark. And then.. The lights flicker open. And then Bell showed up.

"Behold, the Dark Prince is here!"

And he noticed you, and said while his arms crossed. And spoke with a cocky tone.

"You must be looking for me right. If you are, then say hello to Divine Belial!"

He says as he jumps, and lands at a nearby stadium. And pulls out Divine Belial, loads it onto his launcher.
