Later on in the episode the train they take home is hacked by members of the Port Mafia. Atsushi runs into Kyoka again only to find out she is a member of the Port Mafia, and has orders to detonate a bomb. During this encounter Atsushi is able to get through to her, and gets her to reveal the bomb which is strapped around her. Consumed in her self hatred she pushes herself out of the train just as the bomb is about to detonate not wishing to kill anymore people. people however Atsushi leaps after her and rips off the detonator effectively saving her life. Later on they are found sitting ashore Atsushi eventually collapses in her lap from exhaustion. Afterwards they are both taken back to the agency to be treated. Kyoka is then questioned, but insists she will only release intel on the port Mafia if they take her to eat steamed tofu which Atsushi agrees to, but later comes to regret. After this in private Kunikida strongly advises Atsushi to turn her in to the Military Police however Atsushi is very reluctant and decides instead to take her out on a "date". He visibly blushes and stutters after he realizes what he had proposed, but she agrees anyways. The two are seen enjoying themselves all over the city, and Kyoka seems to lose her formerly aloof manner, and even drags Atsushi to go to a Crepe stand. However their date is ended as Kyoka takes them to the final stop on their date. The military Police Station where she intends to turn herself in. Just as she is about to turn herself in. Members of the Port Mafia kidnap her and Atsushi. On the ship they are held captive Akutagawa aims to kill Atsushi, but Kyoka unsuccessfully tries to save him but she ends up in a choke hold. Instead of giving in however Kyoka says how she enjoyed their time together how "the crepes were good" and Atsushi is shocked. Kunikida eventually shows up and Atsushi is given the chance to escape on his own, but he decides to go back and save Kyoka, the two escape together.

Afterwards as Atsushi goes back to the office he worries if the others will accept her only to walk to find she is dressed up in a maid costume with the rest all around her fawning over her. Kyoka soon plees to join the Agency so she could "prove to herself that she could do more than kill", after hearing this Atsushi backs up her claim, and the president allows it. After Kyoka joins the agency Dazai decides to jokingly set her up as Atsushi's new roomate to "protect her". Later Kyoka has her first assignment and fails miserably, Atsushi attempts to cheer her up and buys her a crepe. He also mentions how she might use her supernatural gift in the future which she is very startled by. The two are interrupted by a Port Mafia Member who wishes to bring Kyoka back, but she puts up a fight. Eventually other reinforcements arrive and Kyoka ends up fleeing.

She isn't seen again for a few episodes until she shows up to save Atsushi who is attacked by the guild leader, she tries to protect Atsushi; who is injured, but both end up taken hostage by the Guild. Kyoka feeling as though she can't save anything only kill, does little to escape or help save the city from destruction until eventually Dazai convinces her to help. Unable to stop the ship from crashing into the city Atsushi grows desperate, then he hears Kyoka's voice. She tells him she is able to set up a drone to destroy the ship before it crashes into the city, and that she will not be able to escape with them as she is chained up. Atsushi tries to come up with a different plan but time is up and the survivors are all hurled out of the ship on parachutes. Believing her dead Atsushi is very distressed, only later does he find out from Dazai and the President that Kyoka was able to escape. She arrives on land and Atsushi runs, and embraces her. In the Movie Bad Apple the two are featured largely throughout the fim sharing many funny and badass moments.
