Cuttlefish That Loves Diving
Klein's chosen cogitation image was multiple overlapping light spheres. This mirrored his destiny - the true Sefirah Castle consisted of multiple overlapping light spheres. Lumian's chosen cogitation was supposed to be a red sun, but was corrupted into blood red, then black. This black circle of thorns is interfering with his destiny?
It is indeed mysterious and creepy village, plus somehow everything Lumian imagine somehow keep becoming "real" a moment after he thought about it. I vibe with the theory about the actual reality is the dream and this current reality was a dream about some incident that happen cause of Lumian or Padre that somehow brought The Outer God corruption to the Village and he is the only survivor. And the Monster is the corrupted villager.
