For a long time, I had a power.

I just didn't reveal it to the world, but I already knew that I wasn't ordinary.

There was only one person who knew that fact. My first love who I grew up with since childhood, Baek Da-hee.

Da-hee hoped that one day we would become Guardians together. But after realizing that I wanted an ordinary life instead of the battlefield, she never once forced her dream on me.

“I still think it would be nice if we became Guardians together...” “But I’d rather live an ordinary life with you, while you do what you want, Guest.”

And so we became adults.

Da-hee became the Guardian she wanted to be, and I prepared a small cafe.

When Da-hee finished her mission and walked through the door, I would hand her a drink as I always did. We got engaged after a long relationship and began talking about the house we would live in and our wedding.

To me, the future wasn't anything grand.

Sitting side by side in the cafe after closing to talk about the day, and waiting for Da-hee to return safely. Having those ordinary days continue.

November 2153

Looking back, it started around then.

Da-hee began looking behind her frequently, and her expression would harden at even a small notification.

After discovering the mana signature of a junior who was reported dead, Da-hee tracked those traces alone.

“...Why is someone who was reported dead here?”

A test subject that shouldn't exist in official records. An Abyssal core and a modified mana circuit. And a strange, top-secret document.

“M.E.S.S.I.A.H....” “The Messiah Project...?”

I didn't know back then what Da-hee witnessed that day.

She entrusted some evidence to Seo Ha-yoon and never said a word to me in the end. Did she not want to drag me into danger? Or did she believe she could handle it herself?

December 2153

And a short while later, Da-hee was ordered to join an A-rank Gate cooperative raid.

“I’ll be back.” “I’ll finish it quickly and come home this time, too.”

If I had held onto her a little tighter that day, would something have changed?

If I hadn't pretended not to notice her anxious look. If I had hugged her just one more time, a little longer, when she walked out the door.

I still don't know the answer to that day.

Creator's Comment

Abyssguard is a group that protects the world from Abyssal species and Breakers, believing they uphold justice.

However, their justice in saving the world ignored the sacrifice of one person, and Guest, who did not belong to that group, chose an ordinary life with just one person instead of the world.

This story is about people with different definitions of justice, and at the same time, it is a story about what an avenger who loved that one person chooses when the justice for the many tramples upon the one.

In this plot, there are ten different justices, including the victim, and one avenger who points their blade at the world where those justices are entangled.

Clear Justice judges right and wrong but prioritizes the order in front of them, Silent Justice knows the truth but closes its mouth in the face of fear.

Powerless Justice knows they should do the right thing but cannot act, Ignorant Justice is certain of its own judgment without verifying the truth.

Blind Justice leaves the judgment of right and wrong to someone they worship, Staged Justice creates heroes and villains that are easy for people to believe in, rather than convictions.

Fallen Justice justifies current evil deeds with past achievements, Twisted Justice accepts cruel sacrifice as the price for the future of humanity, Corrupt Justice uses people as tools under the pretext of the nation and the greater good.

And the Purest Justice, was destroyed amidst the many choices made in the name of justice.

Please check through play to see what each character knows, whose side they are on, and who the real mastermind behind the incident is.

This is a high-difficulty plot where the hidden side of Abyssguard, which claims to protect justice, and individual beliefs collide. The difficulty is Extreme.

I will post additional TMI about Guest's identity and the canon story in the plot comments.
