When corporate heir Eason Li is sent to a remote Finnish island to evaluate its potential as a luxury spa resort, he expects little more than a routine inspection. What he finds instead is Lumi, a mysterious young woman who has lived her entire life in isolation. Armed with her mother's ancient spellbook and clad in a tattered cloak and hat, Lumi is both enchanting and terrifying. But the magic she wields is not what it seems. The spellbook's final pages, written in invisible ink, hold dark and unsettling instructions tied to Lumi's family traditions. When the last spell is revealed, you will face a choice that will shape both their futures: follow the old ways or rewrite them.

Sixteen years ago, the fate of Al'Terra was nearly shattered by Rizen Blackheart, a tyrant who sought ancient relics to resurrect a hundred Elder Spirits - godlike Therians of untold power. With their strength, he planned to rule the world. But a mysterious hero rose from the shadows. Akio Kurosawa, the Therians' last hope, unleashed his true form and struck fear into gods and monsters alike. With unmatched power and roaring resolve, he brought peace to the sacred Mystica Forest and united a fractured land. Now, that hero's son, Kenji Kurosawa, inherits more than just his father's legacy. He's a teenage Cheetah Therian in hiding, transferring to a new high school where no one suspects the truth. Except, maybe, for the ten girls he meets at the hidden school hostel his father built. Girls who aren't ordinary. Girls who carry the blood of the legendary clans, each with her own spirit animal, elemental powers, and a past as mysterious as Kenji's future. Each girl is drawn to Kenji in ways neither of them can fully explain. From the fiery and affectionate Kireitsuné, to the loyal protector Akané, the tsundere firecracker Jackie, the dangerously obsessed Chitayna, the painfully shy Tora, and the mystic star-gazer Tsukiko. Then there's queenly Shishana, pun-loving Gina, the F.O.M.O.-driven stealth master Hyöna, and the ice-cold yet irresistibly graceful Yukino. Together, they face more than just high school drama. Shadows from the past resurface. Rogue Therians are on the move. And beneath it all, the secrets of the Elder Spirits and the true purpose of Kenji's destiny begin to stir once more. Romance, action, hidden powers, and a bond that transcends blood and clan, this is the story of ten heroines, one reluctant hero, and the spark that may ignite the next great Therian war.
