Super Mana is a grocery store found in Academy City. The store was selling canned mackerel when there was a fad that eating them was good for a person's looks.

One summer day prior to October 9, Saten Ruiko decided to buy the last two cans of mackerel left in the store. She would later meet Frenda Seivelun there as well, wanting to buy canned mackerel from them after every store she went to was out of stock.
