Miku Katana

Miku Katana (real name Miku Ha) is a human female warrior, currently serving in the Undercover Defence Force (her grandfathers organisation). Before that, she was a member of the Agents of A.C.E. 
Born in England from Japanese heritage, Katana inherited her fathers criminal empire in New Chinatown at just 17.  There, she built up a moderate organisation from the ruins her father had left her. Unfortunately for her, all of her progress in the organisation was laid to waste when Richmond Clay and the Agents of A.C.E shut it down. She duelled with Clay and scarred him, but she respected him as a warrior. She was arrested and her empire was quickly disbanded shortly thereafter.  
Katana’s respect was later shown when she donated her property for temporary use from prison for the agents after they had lost her base. This was primarily under the condition that they were successful in shutting the Mob Dogs down, as she had a grudge against Sweety and Hunny. 
When Richmond Clay was severely injured, she worked with Clive Clayton to find a crime boss she had ties to, in exchange for a few years off of her sentence. Together, the pair stopped the crime boss and ended on good terms, despite Katana very briefly betraying Clive.
Katana’s fate with the Agents was solidified when Gentleman Beast engaged a mass breakout of criminals, some of which to work in league with him, including Katana, to join his Leauge of Adversaries. She shortly after leads an attack on the agents, however this fails and she is forced into A.C.E custody. 
During her time in A.C.E custody, Clive and Katana bond, due to Clive wanting better training in melee weapons. 
Eventually, despite the bonds she was making with Clive, and, to a further extent, the other agents, Katana betrayed A.C.E to rejoin the League. When she did this, she captured Clive. However, during her time back with the Leauge, she decided that she would rather fight alongside the agents and betray Gentleman Beast. 
Katana was present with the Agents when the Murder of Crows gathered the artefacts to resurrect the Chairman. The katana of her families namesake was one such artefact. This forced her to reconcile with her brother, Hayo. This was in order to temporarily take the blade and have it secure in the A.C.E vaults. This attempt, however, fails and Katana loses her right hand to the Murder. This is replaced by a mechanical one, however she temporarily operated a mech before mastering her new hand. 
When the Chairman was resurrected, Katana helped fight the Concord in Richmond’s absence. She also went on to go on the run with Richmond in 2020, after he was framed by Mr Eams. She accompanied Richmond in the Unknown, where her right hand was regrown by Zengu. She also realised that she had feelings for Clive, which she was going to disclose to him after they had defeated Eams. She was also shown the full extent of his plan in the Unknown. She fought alongside the rest of the Agents on ‘Judgment Day’, where they defeated the electronaughts. 
Clive and Katana were in a relationship 11 years later. She was heartbroken and distraught when the revived Devine killed Clive, which meant that she fought with a passion and a fury in the Battle of the Unknown. 
Six months after the merger, Katana had resigned from the Agents of A.C.E and was living with the Hawk family. When the Vorpal Syndicate kidnapped Kieron and Alex Hawk, she looked after their 14 year old daughter, Keira. She joined up with her grandfather (James Hill)’s organisation, the UDF, to have assistance in fighting the Vorpal Syndicate. There, she befriended White Eyes and fought other threats, including an assassination attempt on Oojah Bjorn. She was also by Alice’s side at the birth of her son, Clive. In the end, with the help of Keira and the UDF, they were able to put an end to the syndicate and rescue Kieron and Alex.
