A young girl with black pigtails and red bows, wearing a school uniform, performs a playful dance, winking, raising her hands, and forming a heart shape with her fingers while saying "Nico-Nico-Ni!" and "I'll Nico-Nico-Ni your heart!" in a bright indoor setting with large windows and orange curtains. The scene abruptly cuts to a man with a shaved head and a red band on his arm, crouching behind bamboo poles in a dark, jungle-like environment.
