Team Amploule One returned from the mission to eliminate Taisei Aranami with an innocent hostage and some bad news that the second target, Jin Masaki, had escaped. Miki and Yuuko interrogated Miss Fujino to see if they could ascertain the location of the bank books her father had hidden. Under the influence of Miki's special drugs, it became obvious that the young woman didn't know anything. Though, that didn't stop Masaki from sending men to abduct Miss Fujino, and they ran over Granny Kimura, one of Yuuko's former patients, with a car during their escape. The entire Black Label team prepared as Fiona tracked Masaki down.

He was located in an abandoned building, but had build up a large army of local thugs and armed them heavily. Miki spotted Detective Isoroku running in, then she proceeded to silently kill all the armed men in the stairwells. She later found a room that had Mikoto and Arashi looking rather close. So much that they never noticed Miki come in and start treating the wounded police detectives. Miki tried to send the two home, but they pleaded with her to let them finish what they started. She allowed them to go on, then handed over Isoroku and Suzue over to Oriha to evacuate. Back in the baths of the hospital, Miki was shocked to learn that Sayo had tried to invite Arashi to join them.

CASE 3: Midnight Guerrilla

The former Black label member Shinichiro Inunaki showed up with a video of Arashi and Mikoto killing Jin Masaki, but he denied he was blackmailing the group. Miki was present with Yuuko as Dr. Mochizuki paid Inunaki for the footage. As they were dealing with the issue of a female arsonist killing Black Label's targets, Miki was trying to deal with the tension between Mikoto and Arashi. A few nights later, Mikoto came to the hospital for help for Yuu Momokino, a fellow classmate, after she was nearly raped by a drug crazy young man. Upon questioning Yuu, Miki learned that Mikoto had learned about a Kabuto Syndicate leader's warning from the cellphone of the attacker.

Miki called to warn the team that Mikoto had gone rogue after the Kabuto leader. They all dispatched to back her up, but they were unable to help Mikoto from saving the Chikage Hizaki, the female arsonist, that she had befriended. Chikage ended her own life by falling into the burning building upon learning of how she had been manipulated and used by her master. However, her remains were never identified.

Side Chapter: Color Way Up North

Miki and Yuuko went out on a mission together up north to eliminate the leader of a growing fanatical cult, Senzen Komine. As Yuuko went after Kimine, Miki blew up the road to prevent his followers from arriving to his aide, and she sniped them all in their cars. The two later went to a traditional Japanese inn to relax, but Miki ended up getting drunk and complaining about finding a man.
