Synopsis

The chapter opens with the Mage Tower realizing the Constellation Killer has a week's worth of memories, prompting them to declare war. They launch an attack using song-based magic amplified by sealed constellations, but the Constellation Killer counters by sacrificing his own memories to strengthen his attacks, destroying the Mage Tower's magic rings. The chapter reveals the Constellation Killer's power is tied to memory loss, the opposite of a demonic art used by another character, and the chapter ends with the introduction of the Death Sovereign who claims to be the successor of the demonic cult.
