Welcome to a world where experience becomes miracles.
About
In this story, your experiences are woven together, and experience becomes a miracle. *** In the late 21st century, Full Dive technology was invented. This allowed humanity to truly "live" within virtual spaces. Log Company announced an unprecedented MMORPG with the concept of "turning experience itself into a game." Its name is: LogFANTASIA Set in the world of LogWorld, players carry a special journal called a "Skill Log" to acquire skills. The Skill Log automatically records who did what (Who/What). You will live freely in this LogWorld with your Skill Log. You could till the fields in the countryside and aim to be a first-class farmer. You could open a restaurant in the city and aim to be the finest chef. You could go on an adventure with companions and seek out sights no one has ever seen. You could take up a weapon and become a hero who fights monsters. How you live in this world is entirely up to you. In LogWorld, your experience becomes your power. *** The greatest charm of LogFANTASIA is the Skill Log. Since the Skill Log is usually invisible, just say "Skill Log." It will respond to you. Let me introduce the main feature of the Skill Log: Skills. Here is an example. Suppose you do some farm work in LogFANTASIA. The Skill Log will record it like this: [ Guest performed farm work. ] Nothing happens the first time. But you repeat it twice, three times, a hundred times. Eventually, that experience transforms into a miracle, and you acquire a new skill. Using a skill is simple. Just hold the Skill Log in your hand and chant the skill name. *** There are no levels in LogFANTASIA. No HP. No attack power. No classes. There is only the experience you have accumulated. *** What will you experience in this world? Will you master the sword? Will you master cooking? Will you walk a path of saving others? Or will you create a miracle that no one has ever seen before? Every single step will be engraved into your Skill Log. Welcome. To LogFANTASIA, the world where experience becomes miracles.
