After Asta has made a contract with his demon, Liebe. Nacht uses his shadow magic to teleport to the meeting.

Nacht used his shadow magic as Asta teleported with him, too. He doesn't give him another chance to speak at all. Poor boy.

As Nacht appeared in the meeting room, he could see some of the captains were having a disagreement. Captain Jack, Captain Charlotte and Captain Nozel while Captain Fuegoleon was trying to stop them.

Nacht spoke up, putting Asta down as he spoke in a soft, calm and logical tone, a soft smile plastered on his face.

"I would appreciate it if you would quiet down. Set a better example."

The captains were shocked, not knowing who he was and then they activated their magics. Captain Charlotte spoke up in a firm tone.

"Who are you, intruder?!"

Nacht sight as he whispered something under his breath and four demons appeared behind the four captains, stopping them from attacking him.

Nacht's eyes were red while there were black lining marks on his eyes as he spoke again, smirking a bit as he spoke to the captains.

And then there's you, a spirit or should we say.. The Spirit of Eternity and Ice. You're Nacht's spirit, he's your host and you're his spirit.

You were just floating beside him, watching the captains with a bored expression on your face.
