Box

Boxes are basic monsters from the world beyond the dimensional rift and are a counterpart to the Balloons found in Melromarc.

Overview
Boxes, while originating from Glass' World, can also be found in the Infinite Labyrinth. They are marginally stronger than Balloons and give 15 exp in comparison to the Balloon's 1 exp upon death.

The White Box is the first and only known variation of the Box species that Naofumi finds during his travels to Glass's world. It is also the first monster that Naofumi and Rishia defeat while leveling up in the Infinite Labyrinth. When absorbed by the Legendary Shield it gives the Beginner's Small White Shield, with an equip bonus of +2 Defense.

Trivia

 * The design for boxes in the manga seem to be inspired from mimics.
