Arguable. The characters are reincarnated and meet again during a short epilogue, but most of the cast is ignored and what happened to them is unknown.
All of the characters are already dead, and all are high school age. One of the character's younger siblings (around elementary age) are shot and killed, and another character's brother (around the same age) dies after falling out of a tree
The main cast is dead people in purgatory, not ghosts. They are, for all intents and purposes, the same as living people in terms of how they function. If ghosts are triggering to you, this show is fine.
