Iron Tager/Biography

Trust You, Collisions, Determination, that which is inherited, Remix Heart
When Tager awoke, he was no longer in Naobi, but within a lab in Sector Seven. Kokonoe was at his side, and he was unable to remember much of his memories. She made up the name "Tager" for him on the spot, and informed him that his new body was a mix of Demon cells and machinery. He attempted to comprehend his appearance in the mirror. At some point later, he personally requested that Kokonoe seal away his all of his memories, so he wouldn't have to remember the massacre of his squad.

Tager's first mission was to find Boundary Interface Prime Field Devices deep inside the 5th Hierarchical City of Ibukido, one of which was the missing Nu-13. Upon his arrival, he caught a glimpse of a green shadow, but he dismissed it and ventured deeper into the lab. Three caskets were present, one each for Mu-12, Nu-13, and Lambda-11, but with only Lambda-11 still present in her casket. He took Lambda away from the facility and quickly returned to Sector Seven, as the Prime Field Device was already deceased and would begin to rot in time. He encountered several Novus Orbis Librarium troops on his way but managed to defeat them, thus starting the legend of the "Red Devil".

In 2196, Kokonoe sent Kajun Faycott to the 15th Hierarchical City of Torifune to find the Burning Red Grimoire, hoping that she could use it to increase Tager's power. The mission was unsuccessful, however, and she used an Artificial Causality Phenomenon Weapon to power him instead. Later that year, Kokonoe discovered Hakumen deep within the Boundary. Tager assisted her with her salvage operation.

Variable Heart
A year later, Tager was teleported to the 11th Hierarchical City of Shinatsu to protect Kokonoe, Kajun, Taro Sasaga'e, Litchi Faye-Ling, and Shiori Kirihito from a group of Fuzzy. Despite the best efforts of the group to fight off the numerous vampires, they could not hold them off. Thankfully, they crumbled into dust, something that Kokonoe had predicted, and both Tager and Litchi assisted Kokonoe in teleporting Shiori, Taro, and Kajun to Mai's location to defeat Meifang Lapislazuli. Tager was not initially happy, having wished to have joined them in the fight.

Arcade Mode
"Originally the captain of a battle unit based on physical strength, he suffered fatal injuries during the Ikaruga Civil War and was forced to leave the frontlines. At that time, the scientist Kokonoe revived him as a cyborg. He is currently assigned as a subordinate under Kokonoe's direct control. He seems to be pursuing Ragna, but his reason is unknown."

Story Mode
Kokonoe sent Tager to the 13th Hierarchical City of Kagutsuchi, where he set devices across the Hierarchical City designed to interfere with Hakumen for the salvage operation. After Kokonoe attempted to use Phenomenon Intervention to retrieve the Hero, she sent Tager to collect the devices he had set so she wouldn't have to detonate them. Tager also had a secondary objective to approach the Sheol Gate to watch a certain event.

At the cauldron, Tager deflected a fatal blow from Yuuki Terumi to Ragna the Bloodedge by grabbing the Geminus Anguium: Ouroboros. After noticing that the cauldron was set to detonate, and having been reassured by Rachel Alucard that both Ragna and Noel Vermillion would be safe since she would teleport them out herself, Tager evacuated under Kokonoe's orders.

Central Fiction
"Originally the captain of a battle unit based on physical strength, he suffered fatal injuries during the Ikaruga Civil War and was resurrected as a cyborg by the scientist Kokonoe. After this, he was assigned as Kokonoe's subordinate, and now pursues the "Grim Reaper" who possesses the "Azure Grimoire." Of the soldiers of his squad, his subordinate Bullet alone escaped the annihilation."

Tager, along with Kokonoe and Makoto, was led by Hibiki to a meeting with Kagura, where Kagura explained the events of the last few months. Tager, like everyone else, had been absorbed into the Embryo floating above Ibukido. His memories had been altered so that he believed the date was 12/31/2199, and that Bullet had always been a part of Sector Seven.

Inside the Embryo, he was deployed with Bullet to Kagutsuchi to find the Azure Grimoire. Litchi found him and asked him if he was hunting for Arakune, which he wasn't, and the two parted ways on friendly terms, believing that they had not seen each other for years due to their altered memories. Later he found found Litchi battling Noel in Roningai, after which they both escaped from the lieutenant. Tager eventually happened upon Ragna at the Monorail and fought him to buy time for the NOL soldiers and Kagura to arrive.

Tager was later transported to Ikaruga by Nine the Phantom and told to kill Izanami to claim his piece of the Azure. He contacted Kokonoe and was told to rendezvous at Yabiko, and if possible, to secure Noel. He discovered Arakune in Kazamotsu, but retreated after being attacked, as the monster’s power had substantially increased since the last time they had fought. Afterwards, Tager stumbled upon Hakumen and was ordered to bring him in by Kokonoe. Although he struggled to, he relented after Hakumen mocked him as a puppet rather than a devil

He would soon make it to Yabiko, where he discussed and compared his distorted memories to those of Kagura, Kokonoe, and Hibiki. Tager was eventually contacted by Bullet in Yabiko, where he told her to not pursue Arakune. However, she ignored him, which caused memories of her to return to the Red Devil. Mai and Noel arrived thanks to Kagura. Tager and Mai had not spoken for some time and both found enjoyment in their reunion.

In Akitsu, Tager found Litchi near its cauldron and discovered that Arakune was not Roy, but a vessel he had created. He then told the doctor to stop and consider all of the people who would mourn her if she failed to bring Roy back. He was later ordered to return to Yabiko and detain Ragna. He did not manage to complete this objective, and instead calculated several teleportation coordinates for Kokonoe to use so multiple people could travel to Japan.

Bullet called out for Tager to meet her in the Colosseum, where she confronted him with her original memories of him as her mercenary squad's captain. Tager revealed to her that his memories of that life had been sealed away, and that he no longer considered himself that man. They fought as one last request from his former subordinate, ending with his defeat, and he was able to see Bullet take her own path in life, without the past to weigh her down.

The following morning, he was sent to Nine’s workshop as part of the strike squadron, where he monitored the control systems. He later evacuated and journeyed to Celica A. Mercury's Church‎ where he set up a teleporter to be activated the following morning. He witnessed Celica’s death before teleporting everyone out of the area. Tager later helped Lambda-11 with organising the coordinates for everyone’s arrival in the frozen space-time of the Embryo.

During Doomsday, Tager evaporated into seithr after his data was backed up by Es.

In the new world created by Ragna, Tager was seen in Yabiko on a mission with Bullet, who had returned to Sector Seven. He was on the phone to Kokonoe.
