The Supreme Sorcerer of Hogwarts

HP + Supreme Sanctuary Sorcerer, single heroine Hermione, with a system.

In 1991, while the new students at Hogwarts struggled with the Levitation Charm, Ravenclaw's Silas Kirill could casually open portals. This outwardly "Muggle-born" freshman had actually awakened as a transmigrator at the age of seven, bringing a mind full of original plot knowledge and a "system" to live in the magical castle four years in advance.

He disdained the constraints of wands on his nature, conjuring shields of light and lightning with his bare hands. While others dodged trolls, he casually unleashed an Avada Kedavra, forcing Dumbledore to "have a chat" with him.

With dual-element magic and maximum snark, Silas became the biggest bug in the world of Harry Potter. His Hogwarts life is a collision of tradition and subversion, and a legendary journey for a "Supreme Sorcerer Reserve."
