That's way too fast… Did it already circle the planet several times… Or maybe it's still there, but it's too fast for my vision to keep up… Klein's mouth twitched, deciding to wait a few seconds to see if the "creature whose speed surpasses imagination" would appear again.
He wasn't worried that the summoned spirit world creature would harm the innocent, as one of the descriptions was of a friendly creature. Besides, as long as he forcefully ended the summoning and stopped the ritual, the creature would be immediately sent back to the spirit world, no matter where the "creature whose speed surpasses imagination" went.
A few seconds later, Klein inhaled after failing to see any response from him waiting. He said with ancient Hermes, "I!
"I end this summoning in my name!"
The chilling air around him instantly vanished as the swirling cold wind died down and the candle flames returned to their normal color.
