Isekai / RPG game like / Fantasy World fever 4

Transmigrated as Maou after he just won battle against human army. Asked to bring change to this chaotic world. Cruel? Massacrer? But he is just a pacifist, not an overlord?!

Harem, bearable (not found of the succubi but at least she's useful). Mc only has his human memory but fast learner. Og self was OP but lacking the knowledge toise his magic he is super weak (will get OP very late) and has to improvised. Strategist MC, kinda overwhelmed by events but trying his best. Average read.

Elite assassin for the King, but executed as scapegoat in the end. The noble lady swore revenge when she turned back in time.

Intriguing plot. Kuudere MC is a badass captain of a 3 elite assassins group. Act as frail sick noble lady during the day. Overbearing ML is the Crown Prince who executed her in previous life (bc she killed his brother) but got interested in her instead this time (not because of love). Classical but entertaining (hooray for strong FL).

Researcher became, novel princess who'll die at 12yo. Her mother the Queen had 4 men, 4 possible dads, all tyrants, all devoted to her. Now who will she choose to use in order to survive?

Funny. Unfortunately becoming repetitive (only c11). Plot not evolving. Strong survival instinct MC. Her dad candidates are a Bloody knight, a sexy spy dancer, a cute dragon mage and a muscle puppy knight, though all are devoted to her as they each though of her as their daughter.
