What the heck is that name?

"Hey, Mister. Can you tell me what just happened there?" the young lady asked, but unfortunate for her, the man in the white robe couldn't gather his strength to speak.

The young lady just gritted her teeth once more, then tried lifting the body. But on her way, she grunted as she realized that the body was just too heavy for her.

She cursed, then put the body back on the ground. She pondered, then sighed. She decided to drag the body to the nearest grass.

When she had already dragged the body, she tried inspecting its core, but to her surprise, there wasn't any core.

At first, she thought that she had just missed it, but alas, it was really real. They were floating, even without a proper grasp of magic?

'Core is the result of the comprehension of magic and also concentration of mana in one's body. But for him to fly, was it from an artifact? No, it isn't. Those powerful attacks earlier couldn't be just from an artifact.' She concluded.
