Okay okay this is an interesting scenario, so I`ll split into two parts for the CG and the DL
For the Chief God:
1.)Cease the conscription of Child Soldiers into the Order and make the minimum age to join 16. However becoming a knight must be consensual.
2.)Eliminate corruption both within the Priesthood and Nobility entirely, individuals who fail to comply will be arrested and have all of their assets seized by the state and redistributed amongst the peasants.
3.)If a King or Queen fails to enforce these laws and/or actively engages in corruption they shall be arrested and stripped of their royal assets, titles and lands.
For the Demon Lord
1.) Reorganize the Sabbath, eliminate all pedophilic aspects of the organization and make the production and distribution of all pedomorphosis spells and potions a criminal offence.
2.) Lilims may only hold the position as mediators and/or diplomats, and under no circumstance shall they forcefully convert a human town/city that is not hostile to monsters. Failure to comply will result in the guilty Lililm being relieved of her duties as a mediator/diplomat and may never be eligible for the position again.
3.) Monstering human girls too young to understand sex to become a criminal offence, and those found guilty of doing so to be sentenced to a maximum of 2 years in prison.
4.) Parasitic mamono (Ropers, Matango and Parasite Slimes) shall only reproduce via impregnation from their husband.
5.) Remove the Queen of Hearts as ruler of Wonderland and replace her with an individual more fit to be a ruler.
6.) Forbid the plants of the tentacle Forest from violating unmarried human women, unmarried mamono and children, both human and mamono.
