She was surprised to see Anos raising his hand to be a candidate to lead a team. After Anos found a flaw in the  magic circle and double the magical effect, Sasha was interested in recruiting Anos. After the lesson, Sasha goes to meet with Anos. Sasha then went to Anos, the other team leader, and mocked him for having only one other person on his team and that being the defective doll Misha who was neither human nor demon. Anos tells her so what if she is? Anos tells her that her grasp of magical concepts is too tenuous also tells her to strain her eye more and peer into the abyss.

Anos used his Demon Eyes of Destruction and she was surprised to see someone else other than her self using the demon of destruction. Anos tells her that her magic level isn't half bad and asks her to join his team so she can get closer to Misha. She tells him that she never considered Misha as her sister, not one. After school, Sasha meets up with Anos and asked for a duel and tells him that the losses had to do whatever the winner says. She also tells him if he wins, she will gladly join his team as he requested. He asked what if she wins.

Anos says that the castle is pretty lightweight and also says if they are only guarding against is magic that means they have no clue about the battle. Anos displays his overwhelming power to Sasha by lifting up her entire castle. She was shocked to see how much power he had. After that Anos spines the castle and threw it away. Sasha and others cast . Anos mumble to him it's a shame that she's the enemy. Anos used the  to stop  and he defeated her on the dual.

She was shocked lowest level of fire element spell, stop , and did believe it. He tells her that he is much stronger than her. He tells her that she has potential and comes to serve under him. Anos tells her to take his hand. She tells him that she will never forget this humiliation and also tells him one day she will get stronger then she will kill him for sure. He tells Sasha if kill him were enough to make him die, he would’ve already perished two thousand years ago and tells her that her little sister wanted to be on the same team as her. She was surprised. She tells him that she stands no chance against him and can’t go against her <Zect> to him. She asked him did he recruited her for his friend’s sake. Anos tells her that’s not the only reason. She asked what else. He tells her that her eyes were so beautiful. Sasha was blushing after hearing that. Anos tells her that she harbors immense magic power and tells her, he has never seen such beautiful demonic eyes before. Later Anos invites her to his house. She comes to his house and has a great time. Sasha asked Misha do you like Anos. Misha tells her that she does. Sasha was pleased to hear that. Misha asked Sasha does she like Anos. She replays by saying never in a million years but Anos can look straight into her eyes.

Anos was glad to see Sasha and Misha holding hands. Anos take Sasha and Misha home. Sasha, thank him and tells him that because of him she was able to make up with Misha. He tells he didn’t really do much. She tells him that’s not true, no one but you will ever be reckless enough to say something like, “come serve under me.” She asked him what would you do if your fate was already sealed. He tells her he will not stress about it if it wasn't a big deal but if he doesn’t like it he will change it. She asked him do you think you can change fate. He tells her sure it’s simple and all he had to do is destroy it. She tells him to come over here for a second. He tells her he doesn’t like to be ordered around. She tells here really childish and tells him would you mind coming over here, please. He tells her no problem. He walks up to her. She grabbed his hand and kissed him and tells him that was a kiss between friends and tells him it was her first kiss. Anos tells her that she has given him something quite valuable. He thanks her. Then he went home.

At the dungeon exam, Sasha stabbed Misha but Anos noticed that she was faking it. Anos tells her method of her betrayal is just too tame and tells her if she was really was going to do it, she would have killed Misha. Anos tells her that all she did as playfully stroke her chest with the knife and tells her he is not buying it at all. Sasha revoked they <Zect>. Sasha says shouldn’t you be more alarmed because Misha was about to die if you don’t do something about it. Anos tells her, it sounds as if she wants him to save her. Sasha laughed out loud. Sasha tells him that Misha was born to be used by her. Anos tells her she has such honest eyes and tells her she will not get away with this. She cast the spell rent. She assumed it will take him at least ten seconds to smash through the magical barrier and heal Misha’s wound. She tries to get away but Anos easily stops. Anos tells her the reason why he didn’t believe what Sasha told. Anos asked her how you really feel about Misha. She used her Demon Eyes of Destruction but it had no effect on Anos. Anos used his demon eyes to freeze her on one spot. Since Misha asked him to let her go, he stopped using his demon eyes and she fell to the ground.
