The awakening of Kirito in Sword Art Online: Alicization – War of Underworld is one of the most pivotal moments in the entire franchise. After spending a large portion of the arc in a near-comatose state, Kirito’s return is not just emotional but completely changes the direction of the war. The Human Empire forces are on the brink of collapse, overwhelmed by the Dark Territory army and powerful invaders from the real world.
Up until this point, characters like Asuna, Alice, and others struggle to hold the line without Kirito’s presence. His absence creates a noticeable gap in both strength and morale. When Kirito finally awakens, it marks a dramatic turning point where the tide of battle begins to shift. Understanding how and why this moment happens reveals its deeper importance in the story and why it stands as one of the most iconic scenes in Sword Art Online.
Why Kirito Was Unable to Fight
Before his awakening, Kirito is mentally incapacitated due to damage to his fluctlight during the events in the Underworld. This leaves him unable to respond, act, or even communicate properly. Despite being physically present, he cannot contribute to the battle, forcing others to fight in his place.
This state is significant because it highlights Kirito’s usual role as a protector. Without him, the burden falls on other characters, who must step up in his absence. It also builds anticipation for his eventual return, making the moment of awakening far more impactful.

Kirito’s awakening is not caused by a simple recovery but by a powerful emotional trigger. The combined efforts of his friends, including Asuna, help reconnect him to his sense of purpose. Memories, bonds, and the desire to protect others play a crucial role in bringing him back.
This moment emphasizes one of the core themes of Sword Art Online, which is the power of human connection. Kirito’s strength does not come solely from his abilities but from the relationships he has built. His awakening represents the culmination of these bonds, turning emotional energy into action.
Kirito’s New Power After Awakening
When Kirito returns, he is significantly stronger than before, wielding enhanced abilities tied to the Underworld’s system. His connection to the environment allows him to manipulate objects and energy in ways that surpass previous limitations. This includes using the Night Sky Sword and other abilities at a much higher level.
Kirito’s control over the Underworld reflects his deep understanding of its mechanics. He is no longer just a player but someone who can influence the world itself. This transformation makes him a decisive force in the ongoing war.
Kirito’s return immediately alters the flow of the battle. Enemies that once seemed unstoppable are quickly overwhelmed by his power. His presence boosts the morale of the Human Empire forces, giving them renewed hope and determination.
At the same time, his actions disrupt the strategies of the opposing forces. By taking direct control of key moments in the fight, Kirito prevents further losses and stabilizes the situation. This shift demonstrates how crucial he is to the outcome of the war.
Kirito’s awakening also has a significant impact on the characters around him. Asuna, who has been fighting tirelessly, gains renewed confidence and support. Alice, who carries a heavy burden, is no longer alone in facing the enemy.
For other allies, Kirito’s return serves as a symbol of hope. It reinforces the idea that the fight is not lost and that victory is still possible. This emotional impact is just as important as the physical changes on the battlefield.
