Reincarnated as a Succubus, From the Start Leading the Fourth Disaster to Fight the Black Beasts

Congratulations! You've transmigrated!

You're now a little succubus princess!

All you have to do is deal with a little 'trouble from within and without,' and your adventure can begin!

Trouble from without!

A transmigrator named 'Xi'er' unified the demon race, started a world war, and destroyed your country!

Trouble from within!

You're being hunted and have no choice but to hide in a goblin lair, but they'll catch you any minute now!

All right, transmigrator!

Begin your journey in another world!!!
