Heaven Spider's Butterfly-Capturing Web - False Moon

The Last Word of Eirin Yagokoro from the world of eternal night (a Touhou LW original). This attack differs from the original because it was merged with her spell, which creates a sealed room. She uses multiple surveillance networks to observe the moon and the Earth. They are said to be set up somewhere between the moon and the Earth, somewhere that can never be identified since the boundary between them has been erased. This place could be in the Dream World or another dimension. The only thing that is certain is that this is the Net of Eternal Wisdom that Eirin created to protect the princess and Eientei for eternity.
