Tabi-usagi, alternately named Rambler or Bramble, is an aged male rabbit traversing woodlands and sharing vivid tales of his wanderings. These chronicles earn him admiration among forest dwellers, yet his elusive nature—fueled by constant movement and the generational divide separating him from younger rabbits like Clover—preserves an aura of enigma.

A pivotal childhood trauma defines his past: neglecting duties to explore beyond his home forest, he returned to find it ravaged by humans, his parents slain. This devastation cemented his solitary, rootless existence, driving him to shun lasting ties with any community. The enduring grief from this loss surfaces in his avoidance of emotional bonds and reluctance to revisit his history.

His interactions with Clover form a narrative cornerstone. She venerates him, persistently pleading to accompany his travels when older. He steadfastly declines, citing her youth and inexperience—a refusal reflecting both protectiveness and his unhealed trauma, as he strives to spare her the perils of his transient life.

Despite ingrained isolation, he reveals compassion during crises. When wildfire engulfs Crescent Forest, he joins Clover and Cinnamon to battle the inferno, exposing his latent dedication to communal safety. Amidst the chaos, Clover morphs into a colossal fish to extinguish flames, seemingly perishing in the act. His raw anguish and tears at this sight betray a profound, concealed attachment to her.

His arc resolves in the epilogue: after years of resistance, he conquers his fears and welcomes Clover as his traveling companion. This choice marks a decisive break from his solitary path, signaling tentative recovery from past wounds and newfound acceptance of shared journeys.
