Urged on by her friend, Kaede Honjō begins playing the VRMMORPG NewWorld Online under the name Maple. Not wanting to get hurt, Maple opts to be a shield user with maxed out defense stats, and continues putting every status point she earns in the game into increasing only her defense level. As a result, she is left with slow foot speed and no magic, but her high defense allows her to endure most hits without taking any damage. This, along with her basic-level creative thinking, allows for her to make unexpected accomplishments in the game, its quests and events.
