The Strange Daily Life of a Technician at DIO's Mansion

A Star Series side story (second-person perspective, with the protagonist leaning toward an original female character; probably lighthearted?)

The protagonist is a Magician who has already awakened for the second time in DNF, the grinding game. She belongs to the chaotic neutral faction, and her relationship with Dio is more like that of a partner than a mere subordinate.

After the story in the DNF world progresses to the defeat of Black-Eyed Shal, you arrive in the JOJO world just before Stardust Crusaders begins, passing through a space-time rift that opened for certain reasons. Your coordinates place you near Enya.

The story includes some fan-created elements, such as the origin of the Red Stone of Aja, the ancient world's history, parallel worlds, and Enya having visited the Demon World more than 40 years ago.
