BANG! BANG! Otto could hear the sound of guns firing from behind him as he ran desperately away from his unknown enemy. Suddenly he stopped. For there stood a great, grey wall in front of him. His keen eyes searched for an escape route. But the wall was a dead end. He searched frantically for his gun but it was not be found.

"Looking for this?" said a voice behind him. A voice he knew too well, a voice that seemed very familiar. Otto swerved round to face his enemy and his jaw dropped for he realised why that voice was familiar. There, towering in front of him and holding his gun, stood Raven.

"R-R-Raven?" questioned Otto, his mouth still agape.

"Hello Otto," sneered Raven.

"What happened? Where are your katanas? Why are you acting like this?"

"Orders from my master. He took my katanas for…better uses. You will die," and with no warning she pointed both guns at Otto. "Any last wo-" she stopped abruptly as her head came into contact with a large, heavy metal dish. Laura grinned as she saw Raven sink slowly to the floor.

"What will you do without me, Otto?" Otto managed to give Laura a smile and a small word of thanks before he saw Raven rise to her feet again.

"Come on. We'd better go," said Otto. And the two ran swiftly out of the grey building.

Nero was sitting in his office. He was tense and anxious, what was taking Raven so long? Suddenly he heard a knock at his door. It was one of the guards.

"Sir, two students are here to see you."

"Tell them to come back later."

"They say it's urgent."

"Fine," sighed Nero. "Let them in." On seeing Otto and Laura, Nero was relieved of some of his burden.

"At least you're both safe. Where is Raven? I trust you both know what happened with her?"

"She…she's turned rogue sir," said Otto.

"Rogue? She's turned rogue? Great. First you two disappear, then I have to send Raven to find you and now you tell me she's turned rogue?"

"Yeah, she tried to kill us," said Laura. Then there came an unexpected knock on the door and a guard let himself in.

"Sir, something urgent has come up."
