Yes, this is the untold story of the past. 140 years ago, the era of war, the humans are divided into 4 factions. Scientist of some faction gathered to create a killing machine, Yes, it is the machina. It was successful at first, destroying the 2 faction but, 100 years ago, The machina, No... Ex-machina suddenly began pointing their weapons at their creator. They killed almost everyone in the faction, and dominate the whole terminal. Thus, dividing it to two faction, Human faction and Ex-machina's faction.
It is the time where everything is devastated and ravage by Ex-machina's. The survivor on the incident went to the faction that survived. Yes, this is the faction of Tomoya Kazuto. Their faction is only living in one big cave hoping to hide from Ex-machina's. Tomoya, Dae, and Mavy went to the mission to find the weakness of Ex-machina's. When night comes, they went and search for some weakness. They entered every building in the Ex-machina's faction.
[Tomoya]: Search everything here while we have chance. Don't make loud noises nor be detected by them. If we're lucky, we might find some clues on how to stop them.
[Dae]: Do you think we can stop them? I mean half of us got wiped out already because of this mission.
[Mavy]: Dae! Don't give up on hope. I'm sure that we can finished this with just us 1000 people.
[Dae]: Yes, you're right. Then i will gladly sacrifice my life for that.
[Tomoya]: Quit talking, just focus on completing our objective.
[Mavy and Dae]: Ok, Leader.
After hours of searching, Dae found some paper in the desk. in excitement, Dae shouts. "Oyy, Tomoya! Mavy! I found something!" Tomoya got startled. "Idiot! Don't shout!." Tomoya rushes to go to him. After seeing the paper, they tried to decrypt it but they can't.
"Humans, Sight confirmed, Initiating weapons, successful, Exterminate humans."
The Ex-Machina saw them, They run to the streets of the ruined buildings hoping to to get lose to that Ex-machina's sight. After losing it, Tomoya, Dae and Mavy hide in some ruined building. After a while, Other Ex-machina's also arrived. They searched to every building, While the three of them hoping that they will not be seen. Realizing that they are already trap and waiting to be seen, Tomoya orders Dae.
[Tomoya]: Dae.
[Dae]: What is it? Do you have a plan?
[Tomoya]: Die here.
[Mavy]: Eyy Tomoya!
[Dae]: It's okay Mavy, If my life can save the both of you then let it be. It's my fault after all. Tomoya, Leader, take care of my child. Please.
[Tomoya]: Yes.
Dae went out to their hiding spot. "Oyy, Machines! I'm here! Follow me." All Ex-Machina's are chasing him while Dae runs further and further away from where Tomoya and Mavy are. When the Ex-Machina's are out of sight, Tomoya and Mavy escapes thanks to Dae buying time for them.
They went back to their cave. His sibling, Rika Kazuto and everyone was waiting for them. Rika and everyone cheerfully greets them. "Welcome home." Rika noticed that they are missing one people and get what it means. The child of Dae, Hina, ask's Tomoya where is his father.
[Hina]: Where is Father?
[Tomoya]: He will not come back.
Hina was shocked to Tomoya while Tomoya glares at her with his cold, expressionless eyes.
[Hina]: Huh? What do you mean?
[Tomoya]: Because he's dead.
Hina's feelings bursted, She cried, yell, and accidentally slaps Tomoya.
[Hina]: That's not true! You liar! You liar! Father said he will come back to us, He even said that the humans will win at the end! You lia...
Rika hugs her
[Rika]: It's okay, we're still here. Tomoya, you stinked. How about you take a bath? I'll take care of her don't worry.
[Tomoya]: I will drop by to my room first.
Tomoya leaves and went to his room. Tomoya suddenly cried, and let his emotions out while wrecking everything in his room. Expressing his guilt and regret to himself. "Why don't you just admit that you killed him! You sacrifice your comrades so you can live longer! Admit it! It's your fault that Dae died that everyone died! 999 died for just one person to go back alive! You selfish! You murderer! You should be the one who died!"
Rika saw and heard everything so she didn't bother her brother. Rika gathered everyone to say not to bother Tomoya today. After expressing his guilt. Tomoya sleeps.
