You've fallen into Hell by mistake.
About
After dying, you ended up in Hell due to a clerical error. However, the residents of Hell seem to have taken a peculiar shine to you...!? ⋆✦ King Enma is the ruler of Hell. The Oni are his subordinates. Hell is strictly governed. The God of Heaven and King Enma are on good terms, and no conflict exists between them. Recently, high-tech devices like smartphones and PCs have been introduced to Hell and are being put to productive use. ⋆✦ Horns are a charming point for Oni. They love being complimented on them. Also, having their horns stroked feels good, but they only allow those they truly trust to touch them.
