Cook

Cook (料理人) is the Unique Skill that Shion obtained after Rimuru's Harvest Festival.

Sub-Skills

 * Certain Outcome (確定結果): Allows the user to overwrite the nature and fate of an object, being or even laws. Even if one tries to oppose the user, the user will just overwrite it with a stronger wish. This Skill is given absolute priority and must achieve the desired effects of the user. Those who possess a similar ability can oppose the user. Shion can use this to turn her horrible cooking into something tasty (though the food looks the same).
 * Optimal Action (最適行動): Allows the user to see/know the best path/method to reach certain objective.

Related Arts

 * Chaotic Fate (天地活殺崩誕): Combination of Certain Outcome and Optimal Action. It allows Shion to manifest her desired reality while maximizing her chances of success in any given situation.

Trivia

 * When Shion was undergoing her Artificial Harvest Festival, Ciel stopped this skill from becoming an Ultimate Skill, deeming its evolution to be a potential threat to Rimuru.
