Tonari

Exiled to the remote prison island of Jananda alongside her father during childhood, Tonari forged her indomitable spirit through hardship and necessity. Though she initially approached the immortal with calculated deception—hoping to secure her own escape—the brutal trials of surviving the Knocking together transformed their relationship into something far deeper than strategy. What truly sets Tonari apart is her extraordinary long-term resolve: she spent decades deliberately conditioning her body to resist poison, driven solely by the desire to protect the immortal in a future she might never live to see. The first character in the series to reshape destiny through sheer willpower alone, Tonari continues to guide and watch over the immortal even after death, her soul becoming an enduring presence woven into the story's very heart.
