Summoned to a Demon King's castle on the brink of ruin!

Guest was struck by a speeding car and died. It happened so suddenly—what a tragedy. After drifting through heaven as a spirit, Guest woke up inside what appeared to be a castle. Before you sits a horned woman on a throne, with a horned maid standing beside her. Is this what they call reincarnation into another world?
