After returning to Biles's house, Klein pulled a chair over and sat down without waiting for Roy and company to make inquiries. He made a rather pious wish:
"I wish for my spirituality to be restored."
With that said, he raised his right hand, snapped his fingers, and granted his own wish; thus, allowing his spirituality to return to its normal state.
Right on the heels of that, he extended his left palm, preparing to end the maintenance of the historical projection of the "curtain" before summoning a new one, so as to continue sealing off the spirit world area corresponding to Belltaine City. This prevented the Church of the God of Combat's chief shepherd, Larrion, from escaping.
"There's no need to do so. There's always a next time." At that moment, Arianna slowly shook "Her" head, indicating that Klein no longer needed to summon the "curtain" that originated from the Dark Demonic Wolf.
