Haruka Takamori

A Blade, the title given to the Crescent Moons’ strongest kunoichis, who chased after Noroi from the past into the future. For Takamaru’s protection and to study the current world herself, she began to attend Jippou Academy. Most of the time, she’s just an ordinary girl observing modern society and trying to fit in. Despite being in the same school year as Takamaru, she’s older than him.

Her talent is so great that she achieved the rank of Blade far faster than most, but she could never bring herself to cross the line of giving her past master her chastity, leaving her not truly a Blade when she arrived in the modern age.

While normally a kind, warm, big-hearted girl, she becomes an elegant warrior in battle.

Narika Shihoudou

A girl three years younger than Takamaru and the daughter of his landlord and the head of the dojo he attends, Seigen Shihoudou. A member of the Crescent Moons, she didn’t initially participate in combat. Certain circumstances led to her becoming a Blade and throwing herself into a life of fighting.

Though well-practiced in martial arts, her personality is that of an ordinary girl, and she particularly loves anything sweet. She’s hit on around town frequently enough to be aware of how cute she is, but she still feels inferior when put next to Haruka’s body and personality. Albeit cold sometimes, she’s a caring girl and has positive feelings for Takamaru.

Takamaru Ikusabe

The protagonist of this story. Through a ritual called Dragon Synergy, he can give his partners a supernatural energy known as SP. Although not initially aware, he’s lined up to become the 23rd master of the ninja clan, the Crescent Moons, and is fated to fight Noroi. Upon Haruka’s appearance, he was determined, if not bewildered by the revelations, to fight the Noroi Faction.

Akira Kurogane

The school nurse at Jippou Academy. Holds an unlit cigarette in her mouth at all times. Familiarly referred to as Ms. Akira by the students, she gives them, including Takamaru, advice for their public and private affairs. It turns out that she’s a member of the Crescent Moons and effectively the acting commander in the fight with the Noroi Faction.

Subaru

A Blade of the Crescent Moons, Haruka’s close friend and senior kunoichi. During the effort to stop the Noroi Faction from traveling to the future, she lost to one of their leaders, Ittou Hagane, after which she was imprisoned in Castle Infinity.
