Luna is still awake. Something strange invades her heart—a sudden pain, a premonition.
She places a hand on her chest... and runs to Kaien’s room.
— Kaien!!! Please... protect me...
Kaien jumps awake, startled by her desperate voice.

Luna runs to him and hugs him, trembling with fear.
Kaien holds her tightly, protective.
— Calm down... Luna. I’m here, okay?
Luna looks up at him, still scared.
— Okay... Kaien... idiot...
Kaien smiles faintly. But then...
The Rank O-B ground portal, with a glowing green aura, shifts position and opens right beneath them.
Kaien is startled, but with quick reflexes, grabs his Rank O sword.

Before they can react, both are swallowed by the portal.
Luna screams, panicking as they fall:
— Idiot!!! What did you do?!
Kaien holds her mid-air, tightly in his arms.
— Nothing... calm down, Luna...
Luna tries to calm herself. But as soon as they hit the dungeon floor, a roar echoes through the darkness.
A giant Goblin Boss, wielding a black sword and cloaked in a menacing aura, emerges from the mist.
Luna shrinks back, clinging to Kaien.

Goblin Boss
Estimated Rank: O-B
Hint: Lack of speed.
Kaien observes the system panel. The green aura starts to form around him.
Luna, shocked, points at him.
— Kaien?... What’s that around you?!
Kaien doesn’t answer.

Activate Passive Speed?
Kaien nods. A white aura rushes through his body.
He grips the Rank O sword, firm.
The Goblin Boss raises its dark blade. Its aura pulsates wildly.
Luna steps back but stays by Kaien’s side.
Kaien takes a deep breath and glances at her with warmth before the battle begins.
The Goblin Boss charges, aiming to strike.
Kaien dodges swiftly and counterattacks with a precise slash.
Black blood splashes. The goblin’s aura grows in fury.
But Kaien doesn’t back down.
With all his rage, focus, and courage, he channels the system’s energy and delivers a slashing blow—
cleaving the monster in half.
The green aura bursts like a storm.
The Goblin Boss can’t resist. And dies.

Kaien lowers his sword and turns to Luna.
She runs to him and hugs him tightly, relieved.
— Idiot... thank you, big brother...
Kaien begins to cry, moved, and holds her with all the love he has.
The ground portal opens once again — this time, to bring them back.
Kaien carries Luna in his arms, picks up his sword, and steps through the portal.
They reappear in the bedroom.
Kaien lays Luna in bed. She quickly falls asleep.
[(Elry System)]

He simply nods.

And falls asleep on the floor, while Luna sleeps peacefully in her bed.
And so... the Arc of the Invisible comes to a close.
