Ell advances in his magic class after his companions note his hard work and a conversation about magic types. He is now pursuing the creation of a sentient golem, requiring him to use dark magic to create an "ego". Meanwhile, he struggles to fully understand his own mana and is guided by Serena to finally recognize that mana has diverse traits and feels like a sea of stars. This newfound knowledge sparks a new strategy for his magic and golem-creation plans, while he also grapples with his future and Ellie's upcoming seventeenth birthday.
