Kaito raised his hand, concentrating on the image of the Crimson Castle in his mind. Soon, he felt a gentle vibration, as if reality itself was responding to his wish. Slowly, a circular wrought iron opening began to form in the air before him, and from the center of the opening radiated a reddish light, creating a magical portal that pulsed and eventually transformed into a door filled with glowing red runes.
"Did it really work...?" Kaito was surprised, as this was the first time he had tried to use the Celestial Key outside the Celestial Abode.
With the door now in front of him, Kaito steps forward. The feeling of passing through the door, as usual, is strange like a slight tingling sensation spread throughout his body, but it's not uncomfortable. Kaito emerges on the other side, finding himself in a completely different environment, a vast hall with walls made of ancient stone. However, Kaito suddenly sees a familiar figure running towards him.
