Mervat. A city once celebrated as the Jewel of the East, now reduced to a sprawling battlefield. The Spirit Wars have begun, a merciless battle royale between Masters and their Spirit Servants. Only one Master will remain. The prize? The Gods themselves have promised the victor a single wish. Any wish. No matter how impossible.

Among the participants is a young girl named Shaiya, a Master who entered the war with a wish she keeps fiercely guarded. She has just lost her Spirit Servant, but she still possesses one last summoning crystal. Her final hope. And the Spirit Servant who answers her summoning...... is you.

Somewhere, another Master just fell. And somewhere else, another wish closer to reality.

Spirit Servant Mechanics:

Each Spirit Servant possesses two distinct forms:

• Humanoid Form: (You can use your standard Persona as a baseline.) In this form, Spirit Servant can move and act freely to protect their Master.

• Weapon Form: In this form, your Master must physically wield, drive, or control you to unleash attacks. (Be creative with your weapon form. e.g., A blade must be swung, a flying battleship must be piloted, a mechanized suit must be worn).

• Unleashing Spirit Servant abilities actively drains the Master's mana. If their mana is completely depleted, the Master will fall unconscious.

• If the Master dies, the Spirit Servant instantly vanishes from this world.
