The Nullification Alice. She can cancel out the Alices of others. While its activation is inconsistent, it seems to be constantly active against Pheromone-type Alices. Originally from Kyoto, she speaks with a regional drawl. Part of the Special Ability Class. Her Alice Stone is mandarin orange. Her Star Rank went from No Star to Single Star. She has a cheerful, innocent personality and lives by the mottoes "Never give up" and "Never give in," while faithfully following her grandfather's teachings. She can be a bit of a crybaby and a klutz, and often pushes herself too hard by putting others before herself.

Mikan's best friend. Part of the Technical Class. Her Alice Stones are light blue and purple. Her Star Rank changed from Double to Triple (as class rep), then to Single (as punishment for protecting Mikan), and is currently Triple. Her Alice is Invention, allowing her to imbue machines with her ideas regardless of their actual structure. Because it is a very rare and highly practical Alice, she is sought after by corporations and billionaires worldwide, having many fans and sponsors. However, since she hasn't fully mastered the ability, the performance of her machines varies based on her mood and preferences. Though she is a great beauty, she is sharp-tongued, greedy for money, lazy, and a glutton. She is merciless with her tongue even toward Mikan. On the other hand, she cares deeply for her friends and family, often helping Mikan out of tight spots while complaining the whole time.

Mikan's partner. Latent Ability Class → Dangerous Ability Class. His Alice Stone is red. He is the only elementary student with Executive status. His Alice is Fire, allowing him to create and manipulate flames at will even without a source. His entire family has Alices; his father and sister (who became a non-Alice after a certain incident) share his fire ability, while his mother had Memory Manipulation. His Alice is the type that shortens his life with every use, and due to his high power, he was forced to become a "shadow operative" for dangerous missions. He is usually calm and rarely shows emotion, but he is terrifying when angered. He used to be closed off to everyone except his best friend Ruka. However, after meeting Mikan, he gradually opens up to her and her friends. Before meeting Mikan, he was bullied by upperclassmen who envied his Executive status. When working, he wears a cat-themed "Alice Control Mask," leading him to be feared in the underworld as "Black Cat." For the past year, using his Alice has sometimes caused him to cough up blood or become severely weakened.

Somatic Class. His Alice Stone is cream-colored. His Star Rank is Triple, though he usually hides this as it was granted for being Natsume's best friend rather than for his own merit.

He is not good with women, but is highly popular among the female students.

Special Ability Class → Dangerous Ability Class. Alice Stone color unknown. Star Rank is Double. His Alice is Shadow Manipulation, which allows him to not only control shadows but also manipulate others through their shadows. While his current rank is Double, he originally had the skill of a Triple or higher. In the past, he lashed out at teachers for exploiting his best friend Kaname; as punishment, his stars were taken away and he was given a "Punishment Mark" (the star under his eye) that can cause intense pain. Because of this, he is called the "biggest failure in the middle school division" by his peers, but he doesn't mind at all.

One of the three principals who manage Alice Academy. The most mysterious figure. Height is 145cm (he was 175cm thirteen years ago). Possessor of the Clone Alice. He looks like a handsome boy around Mikan's age, but he was in an adult form until twelve years ago. He is often seen conspiring with Persona and seems to have his eye on Natsume, while Narumi is apparently his "favorite." He treats the academy as his personal property through his Alice power and, to solidify his position, uses students from the Dangerous Ability Class for dirty work under the guise of "national service."

Dangerous Ability Class teacher. His Alice Stone is the color of darkness. His Alice is Corrosion. As his name suggests, he always wears a mask (covering the upper half of his face), which is one of his control items and possesses the strongest restrictive power among them.

The stone in the earring on his left ear is a special Alice Stone for sealing Alices, which Mikan later destroyed. He is a man shrouded in mystery, with a cross-shaped mark resembling a Punishment Mark under his left eye. In the Flower Princess Palace, he is called the "Masked Lord," and he appears to be hated by the Middle School Principal.
