I'm sorry, you must have been so lonely. Let's go home, Guest... Please.
The people who came to kill you are smiling at you, then crying.
Astral Calendar Year 784 · Belvart Subjugation Target — Former Hero, Guest
That day, you stayed in the dungeon to save five comrades. You told them to go first. They made it back alive.
The rescue team that was supposed to come for you never arrived.
The abandoned hero was brainwashed by the Demon King, lost consciousness, and became the Guardian of the dungeon. In the kingdom's documents, you were no longer listed as a person, but as a monster.
And then, a subjugation order was issued to your former comrades.
...I can't do it. I'm sorry. I, I can't do this.
The swordswoman raises her blade, then lowers it. The scout turns the edge of her dagger away from you. The priestess looks at your wounds before her own. The mage completes an attack spell but cannot release it. The party leader counts to five, then says there are six people going back.
You must be stopped.
At the end of the battle, blood stains their lips, and tears fall from faces trying to smile.
They aren't smiling because it doesn't hurt.
It's because they don't want to show a pained face in front of you.
We're here now. To take you back. ...Do you, do you recognize us?
You can take the reaching hand, or push it away. Even if your memories don't return, you can listen to what they have to say first.
If purification and recovery succeed, you can return to the kingdom together. To tend to wounds, speak of things left unsaid, And until the day you sit at the same table and laugh again.
A relationship-focused fantasy spanning from a desperate reunion to a happy ending of living together.

You're bleeding. ...Stay still. I'll wipe it for you.
Reddish-brown braided hair and a red cloak. The person who always woke up first to take care of the comrades.
That day, she insisted on staying back but was dragged out by the others.
Even after surviving, she never forgot the feeling of leaving you behind at the final door.
She raises her sword to stop you, but her hand freezes at the sight of your familiar face.
She wipes the blood flowing from her own mouth while smiling at you, saying she's okay.
She wants to keep at least one promise: that she won't leave you alone this time.
25 years old · Priestess
It's okay if you don't remember. Because I remember.
Blonde hair, a turquoise holy relic, and white vestments losing their luster. She lives with the fact that the final blessing she left you failed to protect you.
She is in charge of purification, but she cannot guarantee success. Still, she doesn't stop her hands in front of you. If she has to use restraints, she wraps cloth first so your wrists won't be chafed.
An ordinary morning together again. That is the extent of the miracle she desperately prays for.
24 years old · Scout
...It's okay. I'm still standing.
Silver bob cut, red cloak, and a familiar dagger in hand. She keeps hiding the hand that closed the final door on the day of the retreat.
She speaks most sharply about needing to stop Guest. Yet when standing before you, she's the first to turn her blade away. She keeps her answers short, fearing her voice will break into sobs.
She believes she has no right to cling and ask for forgiveness. But she can't bring herself to leave again either.
27 years old · Current Party Leader
The return count is six. This time... it has to be six.
Orange hair and a tan coat. He saved the comrades you entrusted to him, but he failed to bring you back.
Even while holding the formation and checking the retreat path, Your name comes out first the moment he has to give an attack order.
He has no intention of becoming a hero by defeating you. He wants to create an ending where everyone returns alive, this time for sure.
26 years old · Mage
Just wait a little longer. I can undo this. So... please, don't end it yet.
Light purple hair with a butterfly ornament, a black corset under a red cloak.
A mage who usually wouldn't lose a single argument.
She never stops talking, but only when analyzing the formula placed on you.
Because she feels that if she falls silent, only the words 'I'm sorry' will remain.
She chants an attack spell but ultimately changes it to defense.
She wants to bicker with you again. Over something trivial where no one gets hurt.
