Fallen Black vs F Arc Edit
One day, at Fallen Black's base, Hajime revealed the information Reatier gave him. The location of the base of an enemy group called F has been discovered. He decided to send a group, formed by him, Hitomi and Aki. On their way, Aki was bothered by the small size of Hitomi's car and by the smoke of Hajime's cigarettes. Once they entered F's base, they were attacked by a man with glasses, who launched a lot of trucks at them. Thanks to Hajime's driving skills, they managed to evade them. Before Aki could tell everyone about the man's powers, Hajime quickly deduced his power was the magnetism, making Aki angry for stealing her role.
After Hajime beat the man, they were surrounded by many ability users. Using his power, Hajime took Hitomi and Aki's hands and flew to the sky. While resting in some building, Hitomi saw throught a window a small child sleeping inside a tank of water. Upon seeing the child, Aki noticed the terrible power that child held. She said that child's power was called "System" and she was the strongest ability user.
After returning to the base, Fallen Black alongside Reatier discussed the matter. Aki explained the details about System's power and how no one could beat her. Reatier decided to take this matter to the higher-ups in the War Management Committee, however in the end, the fairies decided to ignore Aki's warnings and proposed a plan to attack System with every ability user in the war.
After Hajime decided to attack F and System on his own, Hitomi decided to recruit the other members and destroy F before Hajime. Aki happily accepted to join Hitomi and agreed with her to tech Hajime a lesson. At F's base, Aki and Yanagi teamed up and attack F's members in order to attract their attention, so Fantasia could check the computers to look for a way to control System.
Due to Fantasia not finding anything, Hitomi advanced to next phase of her plan. She would make Yanagi hack the computer which was controlling System's sleep in order to let her sleep forever. Once they located the building where System was sleeping, Fantasia and Shugo decided to stay outside to beat anyone who comes near. Meanwhile, Aki, Hitomi and Yanagi went to System's room, however, when they entered, the saw the whole room damaged. At that moment, System, who was floating in the air, quickly proceded to attack Hitomi. However, Hajime appeared and blocked her attack, protecting them. Hajime revealed that System has accepted to join Fallen Black in exchange for some candies. After Hajime left, Aki and the rest of Fallen Black destroyed F.
After F's destruction, System was named Umeko Tanaka by Hajime and Hitomi. Aki was the one who changed Umeko's appearance, cutting her hair and giving her new clothes. Sometimes, Umeko would stay at Aki's house. Sometime later, Hajime hurt his eye and decided to kidnap a member of Virgin Child, who had the power to cure his eye. However, they ended up kidnapping the wrong person. Then, everyone started blaming each other, but in the end, theydecided it was Hajime's fault and left. Before going home, Aki gave Hajime some medicine for his eye and told him to pay her back later with interest.
Fallen Black vs Hearts Arc Edit
After Hajime left the house without saying nothing, Hitomi decided to ask for Aki and Fantasia's opinion in the matter. Aki guessed Hajime was dating another girl, making Hitomi feel worried.
After Shugo and Yanagi decided to team up against the group called Hearts, Shugo asked Aki to keep a constant vigilance over the building where Heart’s leader, Hatsuhiko Habikino, was hiding. After she managed to spot him once, she learned everything about his power and informed Shugo about it. With her work done, she decided to leave and leave everything in the boys’ hands. Shugo thanked her, something she found very unusual coming from him. Aki answered that he didn’t need to thank her because they were allies. Shugo just smirked at such word, Aki mentioned that it was true they didn’t know each other that long and even though she wouldn’t’ cry if one of them dies tomorrow, she still wanted them to win. When she asked him if that was reason enough to call each other allies, Shugo just said she was right.
Climax of the Fairy War Arc Edit
After Umeko Tanaka’s death and Fallen Black’s break up, Aki decided to side with Hitomi and Shugo. One day, when she was leaving school with some classmates, she spotted Shizumu Sagami outside her school. Upon seeing her elegant and lady-like personality around her classmates, Sagami noticed she was completely different from her usual chatty and outgoing self. He asked her which personality was the real one, but she just answered that both were aspects of herself.
While talking about Fallen Black’s break up and Tamaki Hinoemata, Aki mentioned that before the group’s break up, Tamaki asked her to observe a high school boy called Jurai Ando. Aki used her power to learn everything about his power, including its true form, and informed Tamaki about it. Sagami was intrigued by the true form of Jurai’s power. Aki told him that “Dark and Dark” had a second form called “Dark and Dark of the End”. After activating that form, the useless black flames would transform into inextinguishable black flames, capable of burning everything around, including the owner. Sagami was astonished by this revelation.
After hearing from Sagami about Jurai and Tamaki’s battle which was taking place inside Yanagi’s created city, Aki decided to leave and go inform Hitomi about it.
