Deadly Bad Cooking

From Kokorodatabase

As the name suggests, a number of characters in the game possess horrible cooking skills. Notably, Shirogane Ichigo has a habit of burning dishes at random, even causing fires on some occasions. Other characters, such as Shirogane Kyr and Jishou, have banded together and determined to get better in the culinary arts.

Some of the food has been known to make others sick, even sending them to the nearby hospital. Other inedible dishes are instead turned into paper weights.

Generally, however, it is these folks who are banned from the kitchen.
