As soon as Zephyr finished opening the portal door to the vampire realm, Zephyr turned to the four Elementalist Knights who were standing behind him.
"There are no humans or elementalists in the vampire realm. It would be better if only me and the black knight go there. You guys wait here and prevent the lowly vampires from coming out of their world."
Zephyr decided not to close the portal as it would be a hassle to reopen it again. Besides, there was no way the Elementalist knight could survive once they stepped into the vampire realm. Therefore he advised the three to stay to guard the portal in case some rogue vampires would invade the mortal realm.
The three Elementalist Knights nodded in understanding while Kazuto walked over to Zephyr to get ready to pass through the connecting circle between the mortal realm and the vampire realm.
