Trivia

 * For a time, Ciel stops Shion from evolving Cook into an Ultimate Skill, deeming its evolution a potential threat to Rimuru. However, in the events of Dungeon Erosion, Rimuru's forced absence and the severing of their Soul Corridors removed all the limiters Ciel placed on the skill. Combined with Shion's despair at the fate her master met, she acquired Susanoo at last.
