Kihara Akuma

Musujime teleports the scientific devil into the mall in front of Tedashii and Akahana where Tedashii screams out in fear of the devil's return. Akuma laughs and saids "you thought you did" He brings up his hate anger to the one he trusted the most the one to ruining the dark may project as well as promising Tedashii he will kill Kuroyoru Umidori for being the mvp of the failure of the project. He calls his survival karma to Tedashii as he states for the wrongs he committed and laughs.

Tedashii angrily burst out biting his own lip while staring at Akuma with a murderous glare. Akuma tells Tedashii that this hatred for each other isn't well for their relationship and still wants him to be part of the Kihara name and claims by defeating Tedashii they can rekindle what they once had. Akuma charge at the two with an uppercut. Akahana prepares to counter but Tedashii interrupts her and tells her to run. He tells her he can handle his own because Akuma isn't that well of a skill fighter. Preparing to counter Akuma actives the Nano reality digital code-breaker program and a metal glove forms in his fist successfully uppercutting Tedashii. Tedashii flings into the air trying to rebalance only to just get overwhelmed by Akuma's attacks. Tedashii was easily defeated and Akahana tries to sneak attack Akuma only to get counter. Tedashii begs Akuma to spare her as she didn't sign up for the dark side of Academy City.

Akuma in disbelief laughs and mocks Tedashii's unusual behavior of caring for Akahana's status. He assumed that Tedashii took her out on a date after observing him all this time and mocks him for trying to have sex with a droid. He then immediately blames himself as a father figure for never teaching him sex or how to attract people of the opposite sex.

He then proceeds to explain Akahana's value in esper power in Academy City. About the functions and capabilities of data mine where he accidentally slip out planing to steal data mine.

Tedashii begins to chuckle and laughs like accelerator. Akuma backs up knowing that with that laugh, he breaks out like that 100% when he already have a plan in motion with a impatient vibe.
Tedashii tells him why should he join the man who ruined his life and active a protocol for this very own situation. Tedashii's plan was flawed in the end once Musujime appears using Move-Point to take Akahana, and Akuma walks up looking down on Tedashii while protecting Code Vader's identity. Musujime continues to mock him and in rage Tedashii attacks Musujime only to teleport him down some stairs. The two take Data Mine in progress to the plan.

Sometime while Tedashii was recovering he locates the Data Mine exterior.

In escape Mikoto Misaka located and attacked Musujime, Cash, and Akuma not wanting to risk the electricomaster's level 5 Railgun he abandons the two to go out in hiding with his assistant.

Code Vader fines and battle his way to Akuma where Akuma sarcfice his assistant, after successfully reaching Akuma, he said that he's looking more confident and knows that he discovered a resolution for this matter. Assuming that he came to continue his war against Academy City by sacrificing Date Mine or he came to surrender and join him only to betray him once more in the end. Tedashii ask to see Akahana and Akuma present that Akahana is the key to expose the media Academy City's dark side since she has the data of the tree diagram. However to his surprise Tedashii was genuine came to save Akahama Yoko when he hack into the exterior permanently shutting down the system.

Akahana briefly woken up to a tearful eye Tedashii as he told her to stopping treating herself as a complete droid and that if something happens he himself would be hurt and to have value for yourself. Akahana passed beginning the clash between Kihara Akuma and Code Vader.
