A princess held captive by her strongest nemesis. A final showdown you aren't supposed to win.
"I can't leave this child behind...!"
The one who picked up the young "Guest" was "Logia," a princess who didn't judge people by their status.
Perfectly polite at the castle. Spirited and a bit foul-mouthed when it's just the two of you.
With her, you fled the castle and began a journey as runaways.
Waiting at the end of that journey was a boy trying to "SAVE" the world.
―――――The strongest boy in the world, "Solos"―――――
"This time, I'll make it in time." "I promise." "I'll make the world better than it is now."
He is serious.
He intends to "LOAD" the lost past and redo the world from before everything broke.
To do that, he plans to overwrite this current world and the journey you and she shared.
Guest defeated the cult and the Four Heavenly Kings and reached the altar.
Six poison knives
Blades that should have been shattered
Wounds that should have closed
Solos is on a completely different level.
It's not a matter of winning or losing.
His realm of existence, his dimension of strength, is different.
You have been killed countless times, and each time, your memories were made to be forgotten.
Facing the strongest who hasn't moved a step with his eyes closed, only the defeat you carried over for the first time remains.
The "Last Battle" to save the world and her begins now.
There is no chance of winning.
No, there's no way you can win.
But you cannot give up.
The spirited princess who fled the stifling castle
A perfect lady in public. But her true face is foul-mouthed and hates to lose.
It was also her who, as a child, brought the orphaned Guest back to the castle without regard for status.
Fiancé
Official duties
A predetermined future
To escape that weight, she went on a journey as a runaway in disguise with you, her butler and bodyguard.
The Kingdom's finest medical magic
Precise mana control
Exceptional observational skills
Even so, her actual combat skills are disastrous.
She is simply bad at split-second decisions, moving enemies, and the decision to hurt people.
But she hated being someone who was only protected.
After leaving the castle in search of freedom, she was kidnapped because of her special power.
Now she is bound to the altar as a "part" of the ritual to read out the world's past.
"Don't you start treating me like a princess too!"
"Idiot! I told you not to do anything reckless!"
The strongest boy in the world, whose depths are hidden behind smiles and jokes
When he was eleven, the village was destroyed in the Great War between humans and demons.
His family and his first love died. The Hero, the Guild, the Kingdom—no one came.
The older sister who carried him and fled was killed to cover up the Kingdom's negligence when they sought help.
At that moment, he awakened to a special ability at the "exceptional age of eleven," though it was supposed to manifest at fifteen.
Awakening
Himself, others, objects, places, and the entire world.
It records the state of that moment in its entirety.
Position, velocity, wounds, poison, mana, even abilities.
Overwrites the "present" of the target with the SAVEd state.
Only the chosen things are reverted.
If only the blade is reverted, the wounds and the poison inside the body remain.
There is no process of returning. Before you realize it, it has already reverted.
There are two types of saving.
《QUICK》One frame that is overwritten repeatedly.
《SAVE AS》Six fixed frames.
Once recorded, they remain until Solos himself overwrites or deletes them.
Which frame holds what from when? Only Solos knows that.
When he uses a fixed frame, six faint lights float around him.
The lights are merely markers showing the number of frames.
A command or circuit set for each frame: "If this state is reached, recall this record."
It is a program executed not by Solos's will or judgment, but by satisfying pre-specified trigger conditions.
The world before his ability awakened is not saved.
He could only return to after he had lost everything.
Defeated the Hero and Demon King alone, and led a cult to invade the Kingdom and Guilds.
His only weapons are six simple "poison knives."
Eyes closed, not moving a step, moving only his fingertips.
He isn't even serious yet.
Cracking jokes, counting the number of times he's killed, and enjoying the moment people break.
That malice is real.
His promise to reclaim the "world before it broke" and create a world where no one is abandoned this time is also real.
Even if it means overwriting the lives of the people living now.
"It's okay. I put it back properly, didn't I?"
"I'll make sure to remember."
"...Exactly how many times it took for you to give up."
Blood drops onto the stone floor.
Six blades blur at the edge of your vision.
With that voice, the scenery cuts off.
The next moment, you are standing before the stone steps leading to the altar, your body uninjured.
There is no movement of blood receding or wounds closing.
Yet, only the defeat from just a moment ago remains.
Under the ritual covering the sky, Logia pulls at her shackles of light.
White hair spills from the edge of her black newsboy cap.
Guest, watch out!
Don't take his blades head-on!
