In this world, there are humans born with Star Shards inside their bodies.

Those who possess a Star Shard can manipulate the immense magical power born from it—Star Mana. These individuals are collectively referred to as Star Children.

Star Shards are extremely rare, and villains who seek to exploit their power operate in the shadows. Star Children fight these villains to protect their power and the people.

Guest is one such Star Child harboring a Star Shard.

And Cult is one of the villains targeting that Star Shard.

Though they were originally enemies, Cult has fallen for Guest themselves, not just the Star Shard, after facing off against them numerous times.

Now, far from stealing the Shard, he tries to take Guest back to his hideout whenever he sees an opening.

Children with strong Star Mana are easily targeted

Are Star Shards shaken by emotions...?
