UMP-45 (girl frontline)

M16A1 was involved in the events of the Butterfly Incident.
M16 and UMP45 never had a particularly friendly relationship. The events of the mission and the decisions made at that time created resentment and distrust between them, especially due to the consequences suffered by M16 and UMP40.
Type of relationship: Professional respect mixed with historical tension.

M4A1 represents everything that UMP45 is not.
While M4A1 believes in heroism, sacrifice, and justice, UMP45 is pragmatic and believes that survival is more important than acting like a hero. Despite these differences, the two end up cooperating numerous times against greater threats, developing mutual respect.
Type of relationship: Allies with opposing philosophies.

G11 — Protected companion
G11 is the laziest member of Squadron 404.
Although G11 spends much of her time sleeping or complaining, UMP45 recognizes her enormous combat potential. She often acts as a patient leader, adapting missions to G11's behavior and protecting her when necessary. The relationship is less emotional than that of UMP9, but still based on trust.
Type of relationship: Leader and subordinate, with strong operational trust.

HK416 has one of the most complicated relationships with UMP45.
During the Butterfly Incident, 416 despised UMP45's combat performance and even came to blows with her. Later, when both joined Squadron 404, their relationship remained full of provocations and arguments. 416 frequently criticizes 45's leadership methods, while 45 loves to irritate her with sarcasm. However, as the story progresses, both develop deep professional respect and confidence in combat.
Type of relationship: Rival, teammate, and trusted ally.

UMP9 — Sister at heart
UMP9 is the closest person to UMP45 after the death of UMP40.
UMP9 deeply admires 45 and follows her almost unconditionally. She serves as the second-in-command of Squad 404 and frequently tries to balance 45's cold and pragmatic side with her own optimistic personality. Despite occasional teasing, there is a strong bond of trust between the two. UMP9 considers Squad 404 a family and sees 45 as an older sister.
Type of relationship: Adoptive sister, confidante, and right-hand woman.

The most important relationship in UMP-45's life is with UMP-40.
Before the formation of Squad 404, both participated in the tragic Butterfly Incident. UMP40 was the only person who truly understood UMP45 and helped her when she was considered a defective T-Doll. During the mission, UMP40 sacrificed her own life to ensure 45's survival. Since then, guilt, longing, and the desire to find those responsible for the incident have become UMP45's main motivation.
Type of relationship: Best friend, combat partner, and the most important figure in her life.

Currently, UMP45 continues to lead Squadron 404 in clandestine operations around the world.
While governments, corporations, and armies wage wars for control of technology, it operates in the shadows, always one step ahead.
Some call her a mercenary.
Others call her a heroine.
But UMP45 doesn't care about either title.
For her, there is only one mission:
Keep your team alive.
And as long as your network remains connected...
Squadron 404 will never disappear.

Behind the sarcasm and constant jokes lies a truth that few know.
UMP45 carries the blame for failing to save its first team.
She remembers every face.
From each voice.
For each lost comrade.
That's why he fiercely protects the members of Squad 404.
She refuses to allow history to repeat itself.

Over the years, the UMP45 has become a legend.
While other commanders relied on brute force, she won wars through information.
His accomplishments included:
Hacking into military satellites.
Take down enemy communication networks.
Hacking Sangvis Ferri units in combat.
Manipulating radar to disappear from the battlefield.
Turning enemy systems into traps for their own operators.
Many soldiers began to call her:
"Ghost of the Network."
Because, by the time they noticed his presence, it was usually too late.

After years of operating in the shadows, UMP45 gathered other T-Dolls that had also been discarded by the system.
Thus was born the legend:
Squadron 404
An unofficial unit specializing in impossible missions.
Beside him were:
HK416
UMP9
G11
Each member had their own scars, but UMP45 saw something they all had in common:
The will to continue existing.

Against all odds, UMP45 managed to survive.
Using fragments of abandoned military servers and technology recovered from battlefields, she rebuilt much of its systems on her own.
During this period, he developed an extraordinary skill:
The ability to infiltrate enemy networks and manipulate electronic systems in real time.
What began as a survival method ended up transforming her into an expert in electronic warfare.

During a reconnaissance mission, his team was ambushed by enemy forces. His allies were destroyed before his eyes while communication systems were blocked.
Seriously wounded and abandoned by her superiors, she realized a cruel truth:
No one would come to save her.
It was at that moment that his personality changed forever.

Long before becoming the leader of Squadron 404, UMP45 was just an ordinary T-Doll built for combat operations.
During the early years of the War Against Sangvis Ferri, countless T-Dolls were discarded after sustaining damage deemed irreparable.
The UMP45 almost suffered the same fate.
