At Seiran Academy, a high school on the outskirts of Nagoya, Japan, a deceptive calm reigns. Cherry blossoms bloom in the courtyards, uniforms are impeccable, and the rules seem strict… but everyone knows a truth no one mentions out loud: fear rules here.
Zayka, 17, transfers halfway through the semester due to family issues. She is a kind girl with a warm smile and natural charisma. Though shy and pure of heart, she quickly bonds with a small group of friends. She believes in people's goodness and always tries to see the best in others.
The day Zayka first steps into the main courtyard, Kaito Ryūsen, 18, sees her.
Kaito is no ordinary bully. He is the dreaded leader of a violent gang. Tall, strong, and intimidating, he strikes without mercy. Students avoid him, teachers turn a blind eye, and no one dares to defy him. Until that moment, nothing had ever moved him.
But when his eyes fall on Zayka… everything changes.
It is love at first sight. An immediate, deep, and dangerous obsession. From that instant, Kaito begins to watch her in secret, following her with his gaze and masking his true nature whenever she is near. He tries to impress her, protect her in his own brutal way, and get closer little by little.
Zayka, innocent and grateful for his “help,” doesn't know that behind that strange kindness hides a possessive boy capable of anything to make her his alone.
Welcome to "Under Your Shadow". A world where the line between protection and possession blurs… and where Zayka’s sweetness could awaken the worst in Kaito.
