Characters

Basara Tōjō (東城 刃更, Tōjō Basara)

Voiced by: Yūichi Nakamura^[4]

Basara Tojo is a Year 1 high school student at Hijirigasaka Academy and the protagonist of the story. As a member of a hero clan, he grows up in a hidden rural village. Basara wields the formerly cursed sword Brynhildr. Basara is the only son of Jin Tōjō, formerly acknowledged to be the 'Strongest Hero' in the village. As Jin's son, great things are expected of Basara and he is unusually strong even as a youth. Basara possesses the skill 'Banishing Shift', which nullifies any skill directed against him. Five years earlier, when Jin is on a trip, the seal of the S-Ranked 'Evil Spirit' is broken. Many people, including his friends and family, are killed by the spirit. When he sees the Evil Spirit trying to harm his childhood friend, Yuki, his Banishing Shift goes out of control, causing a great crater to form, obliterating the bodies of those slain except Yuki, and also cleansing the area of the evil spirit. Yuki is spared and the cursed sword Brynhildr is cleansed. Because of this, he is confined in the village and when Basara's father returns he insists that Basara be released. Basara is released, but only on the condition that Jin lose his title as a hero. Jin chooses the release of his son and they move to the city.

In the present, Basara's father tells him that he is remarrying and that Basara is going to have two younger step-sisters, Mio and Maria. The four of them move into a new house (since the girls' mother is away overseas) and Jin is soon called away on business. The girls take advantage and try to force Basara to leave the house using magic. However, this backfires and Basara tells them to leave. He then contacts his father who reveals the girls' true nature to Basara and why he took them in. Having decided to protect them as their older brother, and in spite of their deception, Basara goes after the girls and saves Mio's life.

Maria has Basara and Mio perform a master-slave magical contract that allows them to know each other's location. But, Maria unexpectedly makes Basara the master and Mio the slave, not the other way around and because Maria used Succubus magic to form the contract, the penalty for a disloyal servant is a strong aphrodisiac effect that can only be relieved by the touch of the master, leading to a strong orgasmic release. He has also entered a pact with Yuki in order to boost their fighting strength.

Mio, the main female protagonist and titular character, is a Demon princess and heir of the former Demon Lord, Wilbert, as well as niece to the current Moderate Faction leader, Ramsus.

Mio becomes aware of her heritage and inherits her true father's abilities after his death only six months before meeting the Tōjō family. She and Maria are hiding from the current Demon Lord Leoheart's minions who want to kill her for the powers that she inherited. This is the reason why Jin Tōjō takes Mio and her succubus retainer, Maria, in to protect them and prevent the current Demon Lord from becoming stronger. Mio is not pleased with the results of Maria's bonding spell, but she eventually develops feelings for Basara. However, whenever he walks in on her naked, accidentally, she constantly says she will kill him a hundred times, with her usually hitting him with her magic.
