Net Supermarket

 (ネットスーパー) is the special skill that was granted to the main character, Mukoda Tsuyoshi. Although initally laughed at by both the other Summoned Heroes and the Summoners, the skill became Mukoda's greatest asset.

Description
As its name implies, Net Supermarket basically gives Mukoda the power to order anything from a modern day Japanese online supermarket. This gives Mukoda a tremendous advantage in aquiring food, supplies and other consumer goods. As these items are from the modern era, they are considered top quality compared to their medieval equivalents.

Effects
Net Supermarket can be called upon much like how one would go to a website. Apparently the skill is somehow connected to Earth's Internet and allows Mukoda to surf the online market and make his selections. Then he would physically deposit the equivalent amount of currency into the ordering screen, and the purchased items would appear before him in cardboard boxes. As a result, so long as Mukoda continues to earn income, his skill will provide for whatever he orders.

An interesting side-effect to this skill is that certain ingredients and foodstuffs can actually give a temporary boost to a person's skills after he/she consumes them. The amount of the added boost is dependent on the quality of the Earth ingredient. For example, after giving Fel a feast which included high-quality Wagyu A5 beef, the Fenrir's overall stats increased by roughly 50%. Due to the potential danger this effect causes, Mukoda and his familiars have resolved to keep it a secret. Conversely, alcohol products are considered as debuffs and will actually lower a person's stats for a while.

Another effect of Net Supermarket is the fact that the items purchased are of high quality and could be re-sold in the medieval world for huge profits. A bag of ordinary table salt and a jar of pepper was bought for a few copper coins and sold for 17 gold coins. These items, especially the food, desserts and alcohol, have caught the attention of the gods of that world, thereby granting Mukoda with certain blessings for himself and his familiars.

A final effect is that Net Supermarket, like all other Skills, can be upgraded when the user, specifically Mukoda levels up. As a result, Mukoda can choose certain specialty shops such as fast-food restaurants, bakeries, liquor stores, drug stores, etc as tenants. This is in turn widens his product selections.
