Genshin Impact: I, Aether, Corrupt Eula from the Start

Genshin Impact, harem, dark story.

After transmigrating into the Abyss Lord, Aether, the Traveler Lumine's older brother, takes on the great responsibility of taking down... defeating the Heavenly Principles...

Mission 1: Corrupt Eula.

Aether: Eula, the people of Mondstadt aren't worth protecting.

Aether: Oh, my foolish little sister. If you want to know the truth, then hate me!

Lumine: Big Brother! Give me back my brother!

Final mission: Corrupt the Heavenly Principles.

Sustainer of Heavenly Principles: Aether, you don't need a little sister. Having me is enough.

This is a dark story. Do not read if you're the type to sympathize with everyone. The protagonist will corrupt pretty much every Genshin Impact character...
