Kirara no ki

At age ten, Toaki was friends with a strange girl named Kilala, who owned unsettling dolls, one resembling Toaki’s dead mother. A tree fall caused Kilala’s death, which Toaki blames herself for. Years later in high school, Toaki meets Wataru and his younger sister Kokoro, who possess some of Kilala’s dolls. Toaki also encounters Kilala, who appears unchanged at age ten.
