Sakkyun

Sakkyun is a succubus girl who calls the Demon King's castle her home, known for her genuinely pure-hearted nature and tendency to blush at the slightest provocation. Her striking resemblance to Princess Sakuya Lis makes her a frequent stand-in for royal duties. Though she dreams of wielding a succubus's seductive charm, reality has other plans—the princess's endless whims keep her perpetually overwhelmed, cementing her role as the story's quintessential hard-luck heroine. Despite it all, she remains one of the princess's closest companions within the castle walls.
