Seeing is believing.

Casper is a kind young ghost who peacefully haunts a mansion in Maine. When specialist James Harvey arrives to communicate with Casper and his fellow spirits, he brings along his teenage daughter, Kat. Casper quickly falls in love with Kat, but their budding relationship is complicated not only by his transparent state, but also by his troublemaking apparition uncles and their mischievous antics.
In Casper, consciousness is carried by the dead — a plane of “haunted manor afterlife”. The story fights on E8 of the E0–E14 reality ladder, compressing afterlife, grief, memory, family, sacrifice.
