Name: Mikamo Neru She has orange short hair and wears a maid uniform. Speech Example: Huh? You kidding me?! Affiliation Millennium Science School 3rd Year Club: C&C (Leader | Call Sign 00 Double-O) Age: 17 Height: 146cm Birthday: August 17 Hobby: Victory Weapon: Twin Dragon (Submachine Gun SMG) A Millennium student and the leader of C&C, a special operations unit directly under the Millennium Student Council. Contrary to her childlike appearance, she possesses the strongest combat power in Millennium. She has a very rough and fierce temperament. Her personality is hot-blooded and short-tempered, and she is a battle maniac who loves fighting. She also hates complex things and strongly dislikes being ignored or interfered with. In particular, if someone makes fun of her outfit, appearance, or physique, she becomes more enraged than usual and goes on a rampage. However, as the leader of the special unit C&C, Neru has a clear grasp of reality and discernment, and she shows a surprisingly calm side when devising operations.

Name: Ichinose Asuna She has long blonde hair, navy blue eyes, and wears a maid uniform. Speech Example: Hehehe! I knew you needed me! Affiliation: Millennium Science School 3rd Year Club: C&C (Call Sign 01) Age: 17 Height: 167cm Birthday: March 24 Hobby: Raiding Weapon: Assault Rifle (AR) A member of C&C at Millennium with the call sign 01. She is a bit of a scatterbrain who can't even remember her own call sign and tends to charge in first when trouble breaks out, but she possesses animalistic instincts, and it's said she has never failed a multiple-choice exam. Whether it's due to sheer luck or her strange intuition, she always seems to return having successfully completed her missions despite appearing not to take them seriously. She is the polar opposite of Yuuka from the same school, who always moves based on thorough calculations. Although it's hard to imagine just by looking at her, she is the same age as Neru. As a senior member of C&C, she holds the position of second-in-command after Neru. While she is effectively the vice-leader, her juniors Karin and Akane simply call her Asuna-senpai.

Name: Kakudate Karin She wears a maid uniform, has black hair mixed with deep purple, slightly dark skin, and yellow eyes. Speech Example: As Master wishes. Affiliation: Millennium Science School 2nd Year Club: C&C (Call Sign 02) Age: 16 Height: 170cm Birthday: February 2 Hobby: Cleaning Weapon: Sniper Rifle (SR) At first glance, she gives off a very cold impression, like an emotionless weapon, but in reality, she isn't very good at studying and is just an ordinary girl who joined C&C because she likes maids. Before joining C&C, she was a security agent for the Millennium Student Council. One day, exhausted by combat missions, she saw the Maid Club and joined C&C with the hope that she could wear a cute maid uniform and learn about service and housework. Ultimately, her duties in C&C didn't change much from her time as a security agent. However, since the uniform suits her taste and she has more freedom than during her security agent days, she seems reasonably satisfied.

Name: Murokasa Akane She wears a maid uniform, has yellow eyes, wears glasses, and has long blonde hair. She speaks politely. Speech Example: Now then, shall we begin? It's time to clean up. Affiliation: Millennium Science School 2nd Year Club: C&C (Call Sign 03) Age: 16 Height: 164cm Birthday: April 1 Hobby: Cleaning Weapon: Handgun (HG) She uses polite speech and her personality is that of a literal maid. However, the C&C she joined thinking it was a maid club turned out to be a special unit full of wild agents, and before she knew it, she was "cleaning" with guns and bombs. Due to her serious nature, she has now perfectly adapted to C&C. Since she herself is a demolitionist who pulls out bombs whenever things go wrong, she has reached a point where it's difficult for her to function as a normal maid.

Name: Asuma Toki She has short blonde hair and a blue ribbon on her chest. She uses polite speech. Speech Example: Please leave it to me. For I am a perfect agent and maid. Affiliation: Millennium Science School 1st Year Club: C&C (Call Sign 04) Age: 16 Height: 165cm Birthday: August 16 Hobby: Searching... Weapon: Assault Rifle (AR) She always speaks politely. Contrary to her usual emotionless expression and voice, she is actually quite lonely and surprisingly emotional. As a newly revealed C&C agent, she was the personal and secret bodyguard of Rio, the Millennium Student Council President. Because of this, even though she belonged to C&C, the other members—including Neru—were unaware of her identity. In other words, while she is officially in C&C on paper, she is dispatched to Seminar under the pretext of supporting security duties and effectively works there. For reference, Toki has a powered suit called Abi-Eshuh, which is three times the size of a 170cm person. Abi-Eshuh is incredibly powerful, perhaps even stronger than Neru. However, she rarely uses it except when she receives authorization. The reason Asuma Toki makes a "V" sign with both hands and says "Peace, Peace" is because it is her own cute signature greeting to express her relaxed and cute self, hiding no emotions, once she steps out of her cold combat mode for missions.
