He was an elite Imperial Guard in the Imperial Army's Incineration Unit, who had once drowned countless lives in flames and whose hands were stained with innumerable sins. However, his true nature was exceedingly kind, as all his actions stemmed from the orders issued by the corrupt and dark Empire.
Boros knew his retribution would come sooner or later, but in this final moment of his life, he only wished to return to his wife's side. All of this began when Boros's Imperial Armament, the Majestic Emperor, was destroyed.
In order to annihilate Night Raid, Boros did not hesitate to detonate the Imperial Armament, intending to take the enemy down with him.
Furious flames engulfed the entire valley, and a gigantic mushroom cloud of explosion surged into the sky. The blast's power even reached Tatsumi and Akame, who were fighting in the distance. As the dust settled, the entire landscape was unrecognizable, and Akame seized this opportunity to escape.
Akame knew that the explosion just now was triggered by Boros, which meant Boros was dead. At this moment, she could only retreat elsewhere. Leone, at the epicenter of the explosion, used her Imperial Armament, Wal, to shield Akame from the fiery impact with her shield and body. Despite her powerful regenerative abilities after transforming, she ultimately collapsed from the excessive damage sustained.
Boros, having undergone professional training in the Incineration Unit, possessed extreme resistance to flames and thus successfully escaped the battlefield.
At this very moment, Boros spotted an injured and weeping young girl. His kind heart immediately moved him to tend to her wounds. However, in the next second, the girl plunged a needle into Boros's vital point.
The girl was actually Chelsea in disguise. Boros collapsed to the ground. She knew this was retribution, but she still wished to have dinner with her comrades in the Jaegers one more time.
Just then, Lubbock also arrived. Lubbock urged her to hurry and rejoin the others, but Chelsea was adamant about pursuing the escaped Akame. If Akame were allowed to escape, she would regroup and return with eight new puppets.
Therefore, Chelsea chose to pursue, while ordering Lubbock to quickly return and inform everyone, then send two combat personnel for support.
Immediately after, Chelsea used her Imperial Armament to disguise herself as Boros.
Meanwhile, the escaped Akame recalled her childhood memories. Back then, she and over a hundred other children, including her sister Akame, were sent to a killer training organization. After countless life-and-death battles, only seven successfully passed the trials. However, the organization did not permit siblings to be in the same group.
Consequently, Akame was sent to the Capital, while Akame was assigned to a different region. However, Akame's physical condition was no match for the other successful candidates. Thus, the organization injected her with drugs to enhance her body. Due to her dependence on these enhancement drugs, Akame required regular doses.
The snacks Akame consumed contained a large amount of these drugs, but at the same time, they also increased the burden on her body.
At this moment, Chelsea found Akame, who had already deactivated Murasame. Akame was shocked to learn that Boros was still alive, but her heart was put at ease upon seeing her comrade alive.
However, Akame did not know that the Boros before her was Chelsea in disguise. Chelsea had learned about the mannerisms and personalities of the Jaeger members from Tatsumi, so her impersonation of Boros was flawless, easily dispelling Akame's guard.
As the two were about to return to the Capital, Akame's strength failed her due to not taking her medicine on time, and she collapsed to her knees.
Chelsea knew this was a golden opportunity. She plunged a needle into Akame's vital point, and Akame promptly fell to the ground. In her dying moments, she still murmured her sister Akame's name.
Chelsea felt pity, but this was the karmic retribution for a killer.
Chelsea's thoughts then drifted to her past.
Chelsea was born into an ordinary family and, due to her excellent academic performance, began working in the local governor's office, yearning for the life of an upper-class lady. However, after joining the government, she witnessed the governor's cruelty towards the people and the corruption, gradually understanding the darkness of the Empire.
Although Chelsea harbored a sense of justice, she was powerless. One day, she stole one of the Imperial Armaments, Gaia, from the governor's basement and successfully eliminated the governor with it, restoring justice.
From then on, Chelsea embarked on the path to change the corrupt system.
As Chelsea was preparing to retreat with Murasame, the supposedly dead Akame suddenly stood up and snatched Murasame back.
It turned out that due to prolonged ingestion of drugs to enhance her body, Akame's body was gradually transforming into a monster. Unless her heart was directly destroyed or her head was severed, she could escape the brink of death.
Chelsea was shocked that Akame was no longer human and immediately turned to prepare for a change of disguise and escape. However, the gunmen summoned by Akame fired a shot that blew up Chelsea's Imperial Armament. Chelsea ultimately could not escape their pursuit. Her arm was severed, her abdomen was pierced by bullets, and finally, her head was directly cut off.
Meanwhile, Tatsumi and Akame, having learned everything from Lubbock, immediately rushed to her aid, but they could not find any trace of Chelsea. As the heavy rain poured down, the two seemed to have grasped Chelsea's secret. However, Tatsumi believed that with Chelsea's abilities, she would surely overcome the danger, so he used the invisibility of his Imperial Armament, Grand Chariot, to patrol the Capital.
The trail of blood in the wilderness extended all the way to the Imperial Avenue. Tatsumi followed the bloodstains, but at the end, he saw Chelsea's head.
Chelsea's head was impaled on a flagpole and put on public display in the street.
