As the quartet returns from the Cosmic Archive, Kaito finds himself haunted by a void, an echoing emptiness left by Yuki's absence.
Takeshi tries to cheer him up, "Kaito, we'll always be here for you!"
Hana nods, "You don't have to face this pain alone."
Yet, the pain gnaws at Kaito's heart, and he isolates himself, losing touch with the group's laughter and joy.
Takeshi observes, "Kaito's laughter has dimmed..."
Hana is concerned, "We must help him overcome this darkness."
Meanwhile, the voice of Takashi within Kaito's head grows stronger, offering him power to mask the pain.
Takashi's voice taunts, "With my strength, you'll never feel empty again."
Kaito struggles with his inner demons, torn between seeking solace and embracing the darkness.
Takeshi worries, "Kaito's losing himself..."
Hana resolves, "We must bring him back."
In a desperate attempt to fill the void, Kaito lets the voice of Takashi take over, seeking temporary refuge in his newfound power.
Takashi's voice is intoxicating, "Together, we are invincible."
The quartet confronts him, trying to break through the darkness.
Hana pleads, "Kaito, you're not alone. We'll face this together."
Takeshi adds, "Don't let darkness consume you."
But Kaito, consumed by his pain, lashes out.
Kaito's voice trembles, "You don't understand! Yuki's gone!"
Hana embraces him, "We understand your pain, but we can't lose you too."
Takeshi adds gently, "Yuki would want you to find light in the darkness."
In a moment of realization, Kaito breaks free from Takashi's control, accepting his pain and loss.
Kaito's voice is determined, "I won't let darkness define me."
Hana smiles, "Your strength lies in your vulnerability."
Takeshi adds, "We'll face the pain together."
Kaito, with newfound resolve, faces the emptiness head-on, embracing the quartet's love and support.
Kaito smiles, "Yuki's light will guide us all."
With Yuki's memory as their beacon, they face the trials ahead, knowing that love and unity will light their way through the darkest of times.
