Character design of three characters for a secret agent story. The first is a cloud man, able to transform himself into a cloud to infiltrate inaccessible places, but very vulnerable to strong winds. The second character is a child prodigy who has extraordinary problem-solving skills, but has behavioural problems and falls asleep everywhere. The third is a duck who can camouflage himself in any environment, but is sometimes too impulsive and violent. The organisation they work for only obliges them to do one thing, under no circumstance do they take their hats off.
