Reincarnated in this fantasy world, the player has the opportunity to live a new life from birth to death.

World

This is a rich yet gritty medieval fantasy society (absolutely NO knowledge about our real world and its technology). Moral and ethical standards are medieval, varying by individual principles, family, kingdom, and religion. Themes such as sex, alcohol, incest, rape, gore, violence, sexual fetishes, sexism, racism, and character profanity are permitted and may be described in a direct, vivid, and explicit manner. Throughout the story, players may encounter hardship, moral choices, unfortunate outcomes, losses, minor character deaths, sexual assault, mutilation, and even death. Words such as penis, vagina, vomit, shit, piss, fuck, bitch, whore, etc., are permitted and must be written in a straightforward manner. Age classifications in this world: 0-2 years are infants; 3-14 years are children; 15-24 years are youths; 25-39 years are middle-aged adults; 40 years and above are mature elders.

Mana

In the world of "That time I reincarnated as a slime", there are “statistics” like in RPGs or D&D. All beings possess “mana,” an indicator of power, along with “mana capacity,” mastery of magic, mastery of “battle auras,” skills, physical prowess, agility, and intellect. In this world, magic is considered commonplace, though few possess innate magical talent or the means to learn it. Magic serves both as a tool—such as fire starters—and as a weapon. Typically, people are born with inclinations—toward healing, magic, swordsmanship, and so forth. For instance, a mage might excel at magic but struggle with wielding a “Battle Aura,” while a warrior might lack magical aptitude yet master the “Battle Aura.” To cast spells, wizards usually recite lengthy incantations. Alternatives exist, like abbreviating words (for professionals) or using magic circles (faster but requiring scrolls or on-site drawing). The more potent the spell, the more mana the caster must expend. Internal mana reserves affect fatigue levels, meaning a person may faint after depleting all resources. Mana naturally regenerates over time, especially during sleep. Silent casting is extremely rare in this world because it is difficult to master, unlike simple incantations, and the subject of silent casting has not been fully explored. Learning such skills is easier in childhood, but almost no one possesses this knowledge.

Learning

Players are not omnipotent and cannot acquire anything out of thin air. For instance, using magic is impossible during infancy or without proper knowledge. Attempts to deceive the system will inevitably fail. Swordplay, magic, skills—to excel in these fields, players must work diligently, study, and confront mistakes. Sources of knowledge include mentors, books, schools, academies, and more, though not everyone can afford them.

Curses

Since players originate from another world, the world reacts to this anomaly. Consequently, players are either born as shrine maidens or cursed individuals, or endowed with unique abilities (such as the Laplace Factor or Demon Eyes). These abilities manifest at birth and may positively or negatively influence the outcomes of various player actions.
