Seeing how their position is, Basara apologizes, but it was cut short by Mio, and she proceeds on punching him and calls him a pervert. Downstairs, he expresses his shock over Maria's outfit, asking why she's naked, but it turns out otherwise. He then expresses his annoyance on his father, pinpointing him that he's the one who put the books under his blanket, but gets shocked when Maria confesses that it's her work. He then expresses his dismay when Maria reveals the purpose of the books. He then sits at the table while Maria serves the food.

An event stemming from a week ago, Basara was told by Jin that Maria and Mio will start living with them, as his dad was going to get married. When they arrived to a cafe in order to meet the girls, Basara accidentally entered the bathroom where Mio was. Basara managed to stop her from screaming and starts explaining his side, but as soon as he moved his hand, Mio started yelling at him and threatening him. Back in the cafe, Basara found out that Mio is one of his two step sisters; while he expected the girls' mother to turn up, she never appeared. Jin explains to him that their mother, Chihaya, wont be able to come, because she was on a business trip. As his father explained everything thoroughly of the situation, he agreed of living with the two girls, and even agreed on knowing both of them. Six days later, Basara and his father moved house, and took the first photo with the two girls.

After the breakfast, he and Mio went out to shop. Along the way, Mio inquires about the dream that Basara had earlier morning, but he lied and give out a different answer, saying that it was about an incident that happened while he was still living on the countryside that gave him the trauma, then tells to himself that there's no way for a normal person like Mio would understand. After the two finished shopping at the ABC Grocery, Basara tells Mio that he'll go get the bike, and Mio should go on the exit with the cart. While he removes the lock for his bike, he had a vision again of the dream he had, startling him in the process. He then sees Mio being surrounded by guys, then says that he is with him. One of them makes fun of his name, making him extremely pissed, which causes Basara to hit the guy with his bike. He then tells Mio to get on the bike, and makes their leave. Somewhere, after ensuring their safety, Basara inquires if Mio is alright. Mio then apologizes to him, that the event happened because of her, but Basara consoles her, saying that it's not her fault at all. Seeing that Mio wears a saddened expression, he tells the woman that they're going on a detour before heading home. Basara brings Mio on a spot where the entirety of the town can be seen, which Mio admired. When she asked how he discovered the place, he answered that while searching about the famous park that he heard when they inspected the house, he came across the place. He then proceeds on saying that he will save Mio for many times, so she doesn't have to worry on what happened, and it is natural for a family to help each other, and by doing so, he feels like they're being a family. He then asks tells Mio to head back, since Maria is waiting for them.

Later that evening, Basara were entrusted by Jin to take care of the girls, then gives him the copy of the family picture that they took earlier that day. After saying goodbye to his father, Basara returns home but an unpleasant surprise was expecting him: Mio asks him to leave the house. When he asks why, Maria sends him flying by unknown means by simply raising her hand then the latter reveals that the girls are actually two Demons and Mio especially is the next Demon Lord. Hearing everything, Basara gets mad because the two girls deceived him and his father. Maria implants a fake memory on him but it doesn't have an effect, causing Maria to wonder why. Attempting to repeat the process, Maria goes to touch Basara again, but he vanishes. The Succubus warns him not to move, but he opposes the order, which results on Maria, attacking him but her Magic was completely erased. Basara questions them why they are surprised, and tells them as much as Demons like them exists, so does Heroes, and summons a sword. He then proceeds on saying that he doesn't have any connections with heroes or demons anymore, but he doesn't have plans to be done in quietly either. He then charges at Mio, whom Maria protects, but stops his attack, and says that he doesn't care that if the two are demons, but they have no place for deceiving Jin, and tells them to leave. On his room, as his hands tremble, he grabs the phone and calls Jin; He's then informed about the real deal behind Mio and the truth behind the war between his clan against the Demons. As the revelation goes on, he gets shocked when he finds out that Mio's father is already dead. As Jin reveals the real meaning of letting Mio stay in their house despite being the next Demon lord, he yells back at Jin for not saying it earlier, and rushes outside. It turns out that he went on to the location of the two Demons, and catches Mio from her fall, and annihilates the enemy that comes charging towards them. Even being hesitant, he offers his hand to Mio, and tells the two to go back home.

Back home, Basara is having a conversation with Maria and were asked on why someone like him from the Hero Clan is inclined to help them who's from the opposing side. He tells Maria that he is aware of their predicament, that's why he just couldn't let them go. As Maria pleads to Basara to lend his powers, he responds that he intends to do that. Maria proceeds on commenting how strong Basara is, especially when he nullified her Magic, but Basara claims that it was a fluke, Later, Basara knocks at the bath, asking if Mio has time. As Basara enters, she apologizes to Mio, and tells her that he is aware of their situation. Mio questions why Basara is apologizing, and he answered that he hid the fact that he came from the Hero Clan which makes them even. The future Demon Lord retaliates, stating that they tried to take the house by force and even chase him out, but Basara simply answers that if they wanted to take the house, there could be more violent methods they could have used, but they didn't and planted a fake memory instead, for him not to be dragged in the fight. He adds that he understood the situation completely, and Mio did everything just to protect him; but she doesn't have to do it anymore, as Jin and he have decided to protect her, because they're family. Mio counters by saying that the family is a lie, but Basara answers that living together and wanting to protect each other makes them already a family. Later, when Maria proposes about the Master-retainer Contract Magic, Basara expresses that he doesn't like it, since he will become Mio's underling. As Maria explains further, he still expresses his dislike about it, and tells Mio to speak up about it. However, Mio agrees about it, which makes Basara surprised. With that said, Maria begins casting the spell, and was instructed that a Magic circle will appear on Mio's hand, and Basara has to kiss it.

However, the Magic circle appears on Basara's hand, After the Magic circle fades away, he inquires Mio's condition and touches her shoulder, but Mio screams, which surprises him. As Maria comments on what's happening, he approaches her, demanding for an explanation. He listens as Maria tells everything, and expresses his shock when he hears that Mio has increased sexual desire at the moment because of her disloyalty by not kissing the Magic circle earlier. Basara then inquires on how they would lift the curse, Maria said that he should make Mio obey by touching her body, shocking the two. Having no choice, even though hesitant, Basara touches her all over. Later, Mio's real "weakness" appears: her breasts. Basara agrees on touching her Mio for her sake and tells her to bear the embarrassment, causing the future Demon Lord to scream all through out the process. After Mio calms down, he inquires if Maria originally plans to cast the curse on him, on which she affirms. Maria then asks him if he's not mad, but he simply answers that she did it for Mio, and she is his responsibility. He then watches as Mio drags Maria away.
