Heating Box

Heating Box (熱する箱) is an item co-invented by Shalltear Bloodfallen, Yuri Alpha and Aura Bella Fiora.

Description
At the time when Momonga intiated the "Daily Household Magic Item Improvement Plan", Shalltear upon seeing the example of the refrigerator, came up with the idea to create an item that rather than cools food, warms it up instead. Yuri and Aura also came up with a similar item after studying the Warm Bottle.

Both proposals were sent to the dwarf, Tsuibayaya, who after considering that both proposals were similar combined the details to craft the product. Later it was presented at the "Sorcerer Kingdom's Household Goods Magic Item Fair" where when it was tested was found to required some prior instruction for use as the food within the box exploded. Though it seemed to fail, Momonga believed that the heating box still had promised and required some more fine-tuning.

Appearance
A metal box with a window in front.

Abilities
