In the game, the player follows and controls "Taiga," a 16-year-old male protagonist who is transported to the digital world of Monsters,
which in his universe is merely an online game; similar in concept to Monsters World. In the universe of Monsters, people raise creatures
collectively referred to as Monsters, similar in concept to Tamagotchi. Players raise the Monsters through stages of growth that determine his personality,
the five stages being "Baby", "Child", "Adult", "Perfect" and "Ultimate." Monsters evolve over time by gaining stats and other factors.
Monsters can get hungry, sick, injured or die and need care to recover. The game has over 10,000 accessories to collect and equip on their Monsters,
which alter the character's in-game appearance, such as goggles, or an afro.
