Hyoka was a fair-skinned girl, with short blueish black hair, when she was a Magical Girl the tips of her hair changes to a white hue, her eyes are color gold and she bled from her genitals. So far she has been seen wearing different clothing, the most being a school uniform and the tennis club uniform.
Her emblem when using Tsurara Takahashi's stick is the sign of the zodiac Libra and her hair changes to a light yellow in the ends.
Hyoka was a cheerful, athletic and humorous girl who was shown to be emotionally strong.
Hyoka was shown concern towards Tsurara Takahashi, meaning she cares a lot for her, when she learns that Tsurara is pregnant, she gives Tsurara emotional support to calm her and to make her feel better about her case, she promised Tsurara that she'd care for her and the fetus by trying to get them money in order to have the abortion operation, showing a strong sense of friendship and loyalty to her friend.
When Tsurara committed suicide, Hyoka soon became vengeful where she killed Reiko Maguchi (Hyoka's teacher), who was the one that caused Tsurara's death.
Hyouka's father died and she experienced severe depression causing her to become a shut in refusing to go out and staying in her room for days but came out of it with Tsurara Takahashi's help. This misfortune was not enough to qualify Hyouka for a stick. However, she did take Tsurara's stick to commit robberies and injure others in order to obtain money. In spite of all these acts that can be considered "bad", she does them because she trusts her feelings and believes that she is doing the right thing to achieve the happiness of her friend and hers.
Originally Hyouka did not possess a stick of her own but instead shared Tsurara Takahashi Stick, an electric drill that had the power to twist and destroy something via pointing at the desired object with the laser then twisting the drill to then twist the target to death.
With her admin form, she can now shoot invisible bullets from her index finger, which was shown when she shot two people:
- The name Hyoka means "hail" (雹) (hyo) and "flower, blossom" (花) (ka).
- Hyoka's surname Nagatsuki means "long" (長) (naga) and "moon" (月) (tsuki).
- It can also mean "September".
- It is revealed that Hyoka was reborn as the site admin named Nana.
- In Site Episode 12, it was revealed that the mysterious "Giant Eyeball" was Hyoka.
- From the point where Ichi acts as Admin in Chapter 137, it seems that girls such as Hyoka and Shizuka Ochi did not become Admin and she was able to avoid the destiny of becoming a magical girl with Tsurara Takahashi.
- In the Chapter 139, Hyoka is the only admin left on Earth with Ichi.
