In the Amusement Garden, various ancient myths, diverse fairy tales, novels, famous legends and folktales, or even modern lore, creepypasta-like urban legends, internet memes, and modern creations – virtual and fictional stories of gods, angels, demons, yokai, spirits, ghosts, mythical creatures, monsters, mascots of specific companies or works, characters from the internet, and other beings live. All these virtual beings are called Phantasmal Species. In the Amusement Garden, the world where these Phantasmal Species live, extraordinary humans from the real world are occasionally selected and invited to the Amusement Garden.

Gift Games come in various forms such as simple games, riddles, escape scenarios, survival, competitions, tournaments, or trials. Phantasmal Species become the hosts of Gift Games, setting the rules, victory conditions, and defeat conditions. When participants complete the victory conditions and become victors, the Phantasmal Species award the winners with Gifts that were presented as prizes in advance. However, if participants fail to meet the victory conditions and satisfy the defeat conditions, they may die, get injured, or have their Gifts taken away.

Gifts are anything that Phantasmal Species can bestow upon humans, such as land, buildings, money, treasures, tools, weapons, materials, slaves, creatures, talents, skills, knowledge, traits, superpowers, blessings, divine protection, authority, and so on. Everything is a Gift – all the things Phantasmal Species can give to humans.
