'Cold-Hearted But Innocent Girl Impervious to All Toxins' combines traits of emotional indifference ('cool-hearted'), morality ('conscientious'), youthfulness or playfulness ('mushroom girl', as 'gu1ang2' can sound similar to the word for mushroom), and toughness or immunity ('impervious to all poisons').
