From Tsundere Child Star to Fated Star: A Complete Analysis of Aqua and Kana Arima's Relationship in "Oshi no Ko", Who is the Winner in the End?

In the phenomenal work "Oshi no Ko," aside from the suspenseful revenge plot, the emotional entanglements between Hoshino Aqua and the two female leads—Arima Kana and Kurokawa Akane—have always been a hot topic of discussion among fans. Among them, the pairing of "Aqua and Arima," from their initial confrontational meeting to their later complex bond of mutual support, with its nuanced and tugging emotions, runs throughout the entire work. This article will delve into the evolution of the relationship between Aqua and Arima Kana, exploring why this emotional connection stands out as so special within the entertainment industry filled with lies.

First Meeting and Reunion: The Intersecting Paths of Geniuses

The connection between Aqua and Arima began during their child actor days. At that time, Arima Kana was the highly popular "genius child actor who could cry in ten seconds," full of arrogance, while Aqua, with his mature acting skills, completely shattered her confidence on set. This encounter planted a complex seed in Arima's heart—a mix of awe and slight resentment towards Aqua.

Years later, they reunited in high school. Arima Kana's halo had long faded; to survive in the entertainment industry, she had smoothed her edges and learned to perform with "oily acting" that catered to others. It was Aqua's appearance, with his statement, "The you I like is the unruly one," that reignited her nearly extinguished passion and original intent for acting. It can be said that Aqua was the key figure who pulled Arima out of the quagmire of being lost.

"I'll Be Your Oshi": A Complex Relationship of Salvation and Exploitation

To push Arima Kana back to the top and for his own revenge plan, Aqua orchestrated Arima's entry into B-Komachi and clearly told her: "I'll be your oshi (推し)." This statement became a turning point in their relationship. For Arima, it was the salvation of her acting career and the beginning of her youthful affection; but for Aqua, this "support" was mixed with clear calculation and exploitation.

The complexity of this relationship lies in:

• Aqua's Dual Motives: He genuinely appreciates Arima's talent and wants her to shine. But at the same time, he also sees Arima as an important pawn on his revenge chessboard, using her fame and B-Komachi's activities to get closer to his target.
• Arima's One-Sided Devotion: Arima Kana quickly fell in love with Aqua. She was attracted by his mystery, gentleness, and strength, becoming a typical "troublesome woman," tsundere in speech but deeply caring in her heart. This "girl chasing boy" dynamic added much lighthearted and humorous color to the heavy plot.

The Choice Between Light and Shadow: Why Did Aqua Choose to Push Arima Away?

In his "contract girlfriend" relationship with Kurokawa Akane, Aqua chose Akane, who could understand the darkness within him, as his "accomplice." In contrast, Arima Kana always represented the "world of sunlight" without lies that Aqua yearned for. He was acutely aware that his path of revenge was fraught with danger, so he subconsciously pushed Arima away, unwilling to let her pure world be tainted by his darkness.

When Arima mustered the courage to confess, Aqua's rejection was the ultimate manifestation of this protective mindset. He was not unmoved; rather, to prevent her from being dragged into his revenge tragedy, he chose to sever this potential romance. This act of pushing her away precisely proved Arima's special place in his heart.

Hints in the Ending: Becoming Her Only Star

In the manga's final outcome, Aqua chooses to perish together with his biological father to protect his sister Ruby. However, the story does not end there. In the final scene, the timeline jumps forward several years. Arima Kana, now a top actress, is shining brightly on stage, and in the audience, a figure resembling Aqua holds up a glow stick in her representative color, cheering her on.

This scene is widely interpreted by readers as a hopeful hint: Aqua might have survived in some way, completely abandoned his revenge, and fulfilled his initial promise—to become Arima Kana's one and only "oshi." Although they did not have a traditional romantic ending, Aqua ultimately chose to protect this light in his heart. In terms of emotional belonging, Arima Kana is undoubtedly the "star" who accompanied him to the end and became the寄托 of his life's conclusion.
