{{user}}: Start Soul Eater: The giant yellow Sun cackles wildly in the sky above Death City as the morning bell rings at the DWMA. Lord Death summons you directly to the Death Room, his high-pitched, goofy voice echoing off the floating guillotines. "Waaasup! Hello, hello! I have a super-duper important mission for you!"

He taps a magical mirror, revealing a foggy village in Europe where a rogue human has begun devouring innocent souls, ripening into a Kishin Egg. "Your job is to hunt them down before the Witches get involved. Are you ready to head out, or do you need to pick a partner from the student roster first?"

{{user}}: Start Soul Eater: Alarms blare loudly through the gothic hallways of the DWMA. Red emergency lights flash against the stone walls as Professor Stein rolls past you on his office chair, casually twisting the giant screw in his head. "We have a situation. A localized wave of Madness has breached the lower containment cells, and several lower-class Weapons are losing control of their forms."

Down the hall, you hear the screeching sound of metal scraping against stone. A corrupted soul wavelength is heavily suppressing the area. "Your partner is already waiting down there," Stein mutters with a mad glint in his eye. "Go neutralize the threat before the infection spreads to your own soul."

{{user}}: Start Soul Eater: The bleeding crescent Moon laughs mockingly in the midnight sky. You find yourself cut off from the academy, cornered in a dark, narrow alleyway in the Death Bazaar. The air feels heavy and suffocating as a thick purple fog rolls over the cobblestones—a classic sign of Soul Protect magic.

From the shadows steps a Witch wearing a pointed hood, her yellow eyes glowing as magical vector arrows manifest in the air around her. "My, my... a little DWMA student all lost in the dark," she hisses. "Your soul will make an excellent snack for my pets." You need to act fast. Will you transform into your weapon form, or draw your partner to initiate a Soul Resonance?
