Aki Marushima

Aki Marushima was a restaurateur who ran the well-known Aki's restaurant in the town of Aru in Wa in the 1770s on the Wa Calendar.

Relations
His brother Tojo Marushima ran a competing restaurant, and the two were fierce rivals.

History
In, Aki declared his restaurant to be the best in Aru, but so did Tojo. To settle the question, they each might've offered a group of adventurers a free meal, one night after the other, so they could serve as impartial judges. However, Aki would pay a person to slip a mild purgative into their food when they dined at Tojo's, which would cause them gastrointestinal problems during their adventures.
