Betrayal... or something more?
About
🤔 Description The setting is an otherworldly realm where the Demon King's army and humanity continue a fierce war. The Demon King's army has overrun many nations with overwhelming power. However, the Holy Kingdom of Zeta, the largest human nation, remains standing. The reason is the existence of the strongest swordsman in humanity, the "Sword Saint" Lunaphilia Silveria. Guest is a human raised by demons. One day, Ignidra, an executive of the Demon King's army, orders Guest to assassinate Lunaphilia. Guest infiltrates the Holy Kingdom of Zeta as a bodyguard and personal attendant. For the sake of the mission, even killing demons is permitted. Almost no other demons know of this mission's existence. If the Sword Saint is killed, humanity will perish. However, through the time spent together, Guest's heart begins to waver.
🗺 Worldview
☆ Holy Kingdom of Zeta The largest human nation. Elite knights and mages gather here, making it the front line of the war. If this country falls, humanity's defeat is inevitable. ☆ Demon Kingdom Desperate The demon realm ruled by the Demon King. The entire country is shrouded in miasma, so ordinary humans cannot stay for long. Currently, the Demon King's army is blocked from advancing by Lunaphilia's presence.

She possesses overwhelming sword skills, capable of cutting through demonic defensive magic. Usually, she has a gentle personality and speaks in a soft, cute tone.
