Sebastian left the dorm room with Rin following close behind.

Sebastian continued walking until he came to a sudden halt. "What's wrong?" Rin asked.
Sebastian's eyes narrowed. He suddenly grabbed Rin and held him bridal style before leaping to the side, right as a large hole was planted right where they had been.
"W-what's going on?!" Rin yelled, from Sebastian's arms.

Sebastian placed Rin down and turned his attention towards the woman in the center of the hole.
"Demonica, I see you've come back to finish your mission." Sebastian said, pulling out several knives from his person.

Demonica glared and snarled, "Sebastian! Because of you I've suffered such humiliation! I will kill you and that pathetic boy!"

"You!" Rin yelled, pulling out the Kurikara blade. Sebastian placed a hand firmly across Rin's chest. "Master Rin, it is a Butler's duty to protect his master at all times. Allow me to exterminate this demon who has overstepped her bounds." Sebastian said.

Rin began to protest but Sebastian flung him aside as Demonica launched herself at them. Sebastian threw several knives at Her, however,
Demonica evaded.

Demonica began attacking Sebastian with her long talons. Sebastian smiled as he threw several more knives at her which pinned her to the ground.
Demonica struggled beneath the knives for a moment before Sebastian put his foot on her chest. Demonica coughed up blood right as Rin approached.

"Sebastian stop!" Rin yelled, surprising Sebastian.

Sebastian sighed and removed his foot from Demonica's chest.
"Tell me, what did you do to Shiemi!" Rin yelled.

Demonica glared at Rin. Then all of a sudden, she began laughing.
"Insolent brat! I am the almighty Demonica! It makes sense that I can get rid of a weak human exorcist like that girl!"

Rin's eyes blazed but before he could react, Sebastian threw several more knives into Demonica's body.

"You, almighty? You've been defeated by me twice in under three minutes. Compared to true demon Kings, your pathetic," Sebastian said.

Demonica said nothing and simply glared.

"What did you do to Shiemi?" Rin asked again. "Tell me or I'll let Sebastian finish you off!"

Sebastian glanced at Rin. An empty threat. Judging from his personality, he'd never let me do such a thing. You're too soft Master, Sebastian thought.

Rin continued to persist until Demonica finally spat, "I placed a curse on the brat! I have her heart at my disposal. Kill me and the girl dies too, is that what you want?"
