The Janitor of the Magic Academy is an Alchemist

Caelia had always been worthless. Just like her twin sister Selene, she was born to the Dragon Knight Clan with a strong bloodline affinity and having awakened a powerful Void Soul. She should have become a great Mage, but while Selene soared, Caelia floundered. Deemed talentless, when she flunked out of Velgrin Academy, it was Selene’s pity that kept her on the grounds… as a janitor.

Years passed, and while the world forgot her, Caelia stubbornly pursued her love for magic using the academy's resources. At the end of her fruitless life, she made one final discovery: a new path of cultivation: Alchemy.

Then everything changed. After confiding in Selene, Caelia woke in the body of a young boy, with fragments of the late headmaster’s memories burning in her mind. A Pinnacle Archmage, now dead from a forbidden experiment… yet somehow merged with her.

And worst of all? As fragmented as they were, his memories whispered one undeniable truth: her loving sister might have wanted her dead.
