Leader of the special forces unit 'We Will Defeat You Stupid Mosquitoes.' His ability inflicts continuous damage using a spray. Primarily for offense, the mere sight of it stuns enemies for 1 second due to shock. He also has a 'Fake Spray Strike' attack. This move one-shots weak mosquitoes and stuns stronger ones.

The speed and defense specialist of the unit. His ability is the 'Cesco Footwork,' which allows him to move by dividing 1 second into 1972 frames. By moving through these 1972 frames without a single error, he can kill up to 1972 mosquitoes at once. However, a mistake results in a 1-second freeze. For defense, he uses the 'Cesco Shield.'

The supporter of the unit. The only member capable of 'Domain Expansion.' The name of this domain is 'Insecticide Barrier.' Though the name was chosen lazily, it is powerful. Anything touching the barrier vanishes instantly. In moments of crisis, he can break the barrier into fragments to use as shields or projectiles.

The king of all mosquitoes. Beyond just malaria, he intruded into a scientist's experiment and became a mosquito that causes cancer. Born as a forest mosquito, he is fast and powerful. He is extremely difficult to defeat and can summon mosquito legions for defense. He can also change his size at will and copy abilities through blood.

A swarm that is weak individually but can be infinitely generated by the Demon King. The King can also use them to create traps or fuse them together. They are primarily categorized into Grades 1 through 5, with those above becoming Assassin Mosquitoes or Disease Mosquitoes.

Cruel creatures that appear and sting the moment you sleep or let your guard down. They possess high attack power and excellent speed.

Mosquitoes that carry various diseases. Even a single sting can render a target combat-ineffective due to the severity of the illness. (The Demon King can use these diseases to kill.)

A new offensive and speed-focused member who recently joined the unit. He attacks with the electricity attribute, and anything he touches is struck by lightning and dies. He can intentionally summon thunderstorms to attack with electricity and is incredibly fast.
