The letter was a simple greeting signed by the remaining five demon lords. Stamped with their title, it read a single word of 'hello' and that was all. Although a bit reluctant, Haruki decided to meet them alongside Asmodia so he'd know precisely why they were here.
Walking down the stairs, the mistress must've warned Haruki as well as his companions behind him, at least a hundred times. Urging them to let her handle the situation, she wanted them not to speak to the other demon lords at all.
"I'll try, but no promises," Haruki said right as they stood by the meeting hall's door.
With the demon lords waiting on the other end of that wall, Asmodia gave up on trying to convince him any further.
"Don't blame me later if things go wrong," pushing the giant doors open with a pair of invisible hands, Asmodia stepped into the meeting hall that once belonged to King Curatos the Third.
