In the floating kingdom of Astravale stands Valkyrie Academy—an elite institution where only the world’s most gifted young women train to become battle maidens, spirit knights, and arcane queens.

For centuries, no male has ever been admitted.
Until Haruki Aetherion.

Marked by a mysterious celestial crest that reacts only to female mana signatures, Haruki is forcibly enrolled after the academy’s ancient barrier recognizes him as a “Singularity Candidate”—a being capable of amplifying and stabilizing the overwhelming powers of the Valkyries. Surrounded by prodigies who view him as an intruder, a liability… or a rare treasure, Haruki must survive political schemes, jealous nobles, and duels disguised as “welcoming ceremonies.”
But Haruki is far from ordinary.

Calm, observant, and secretly wielding a dormant star-forged ability, he begins forming contracts—not of ownership, but of mutual strength—with the academy’s strongest girls: a proud flame empress, a silent ice duelist, a mischievous wind spirit summoner, and even the untouchable student council president.

As threats from rival kingdoms and ancient skyborne beasts close in, Valkyrie Academy realizes one truth:

Haruki Aetherion isn’t just the only male in the academy.
He may be the axis upon which their entire world turns.

And this time, he’s not content being protected—
He’ll build his own constellation.
