Demon Scabbard KitN sprite
The Demon Scabbard (魔剣の鞘 Maken no saya, lit. Sheath for Magic Blade, Sheath for Demonic Blade?) is the Key Item of Leonil, a boss character from Knights in the Nightmare. It is an elusive item that appears in Scene 16 in the right-hand knight statue, but only after the original one has been destroyed, and the statue has respawned.
