I'm not entirely sure about the specific plot of this visual novel as it may not be a widely known mainstream one. But generally, in a visual novel, the plot could involve the relationships between the characters, their adventures, and how they interact with the tentacle and witch elements in the story.
Well, without having experienced it directly, it's difficult to say precisely. However, if it follows the common trends in visual novels, it might revolve around the witches' powers and how the tentacle element plays into their world. Maybe the witches have to face challenges related to these tentacles, or perhaps there's a mystery surrounding them that drives the story forward.
