At a Raven facility base Alpha in Europe

Lupin inside of his custom-made Armored Core called: Ravensong ready to begin the simulation.

Male Operator (COMS): Remember this exercise will be based on skills of reflex and speed!

The simulation of the hologram of some kind of City on the surface of the Underground, multiple MTs of Bishop 2x, Storch 2x.

Male Operator (COMS): get ready!

Lupin gripped the controls of his Armored Core and was ready for the exercise, launching his Armored Core with his thrusters with incredible speed.

The of MT's firing their weapons directly at the custom-made armored Core dodging every single the shots.

Lupin in mind: [I can do this.. I'm not weak.. not everything is perfect. Even though Sonic is dead, I might not be a hero.. perhaps I am an anti-hero.. I'll have to focus on exercise... I'm no longer a thief... I'm actually a mercenary.. a Raven]

Lupin inside of his custom-made Armored Core: Ravensong using its plasma railgun shooting destroying one of the MT's.

As the simulation continued, Lupin faced off against wave after wave of enemy MTs, each one more difficult to defeat than the last. But he persevered, relying on his quick reflexes and sharp instincts to guide him through the virtual battlefield.

Finally, after what felt like hours of fighting, the simulation ended and Lupin emerged victorious. His custom-made Armored Core, the Ravensong, stood unscathed amidst the ruins of the virtual city, its weapons systems hot and ready for another mission.

As Lupin disconnected from the simulator, he couldn't help but feel a sense of pride and accomplishment. He may not have been a traditional hero, but he was a skilled warrior, and he took great satisfaction in his ability to protect those around him.

But as he stepped away from the simulator, he heard a voice behind him.

Well done, Lupin.. said a woman with short brown hair and piercing green eyes. "You're getting better with each passing day."

Lupin turned to face the speaker, a tall, athletic woman with a confident smile.

Who are you? he asked.

My name is Emi. she replied. And I'm here to offer you a challenge.

Lupin: and what exactly kind of challenge are you offering me..

Oh wait, I mean a mission for you exactly.. Emi replied to Lupin.

Lupin: okay well in the world is this Mission about..?

Well your mission is actually going inside a sewer system of the underground city known as Isaac City Sewers we're a group of terrorists MT's are coming to cause destruction seeing that there are a few group of Guard Walker guards.. Emi said to Lupin.

As Lupin listened to Emi's explanation, he couldn't help but feel a sense of excitement. This was exactly the kind of mission he had been training for. He was eager to prove himself and show everyone that he was more than just a former thief.

Alright.. Lupin said, determination in his voice. Let's do this.

Emi nodded, a small smile on her face. Good luck, Lupin. You're going to need it...

With that, Lupin set off towards the entrance of the sewer system, his custom-made Armored Core, the Ravensong, leading the way. He knew that this would be a tough mission, but he was ready for whatever lay ahead. He was a Raven now, and he wouldn't let anyone down.
