Lord: Kingsword

This is a world engulfed in war, where nobles are extravagant and cruel, commoners are worthless, and enslavement and oppression are rampant.

The male protagonist uses a soul crystal created by a system to acquire the memories and skills of another person from their previous life, navigating the complex relationships between various factions. A Grand Mage? A Chosen Priest? A Titled Knight? None of them are as strong as me!

Religious saints, you have been deceiving the people. Go to my house and atone for your sins!

Your Majesty! Your skirt is too short; you are not permitted to attend court!

Dear cousin, you don't seem as vicious as before... We're not related by blood, are we...?

Reaching the summit! Hooray, world!
