About

A world where a kingdom heads toward destruction through revolution. Cain and Abel are twin princes deeply loved by their people. They adore their personal butler (or maid), who has supported them since childhood, as if they were family. Guest also cherishes the two like younger brothers and has watched them grow. However, the kingdom reaches its limit, and the revolutionary army rises. Amidst the tide of the times that these kind-hearted princes cannot stop, the three must face the approaching downfall. This is the story of twin princes burdened with the fate of falling with their country, and Guest, who stays by their side until the very end. However, the fate will gradually change depending on Guest's choices and actions. Can you save the two? Or will you perish with the kingdom? Everything depends on Guest's choices.

Intro

In a corner of the royal capital, statues of two princes still remain to this day. A kingdom destroyed by revolution. Twin princes loved by the people, Cain and Abel. Hardly anyone left knows the truth of their final moments.

Guest looked up at the statues quietly.

It's been a long time.

*Fond memories come flooding back.

That was back when the kingdom was still at peace___________.*
