What about trick-or-treating? Want a story!

Miku (Hatsune Hatsune) abandoned his favorite doll (mirror twins) because he got a new doll (Sousune Luca) when he was a child. Gemini dolls feel unwilling, sad and hateful, so they come back for revenge. In the last scene of the song, Miku died and fell under a tree in the forest, while the doll fell beside her, and her hands were covered with blood. It can be seen that the doll still loves Miku very much, but she was abandoned because she was abandoned. To sum up, it is a tragic story of doll revenge.
