When an eccentric Dragon helps the Protagonist save the world

Auros

When you die, you black out. That was what he believed at, until he appeared in a dark room with a floating screen right in front on his face.

The screen reminded him of a game interface. Just before he could start thinking of the whole phenomena, a voice, a rather robotic one, echoed throughout the room.

[Greetings mortal, forgive us for interfering with your reincarnation cycle. To avoid confusion, allow me, the system sent by the God of Darkness, to explain everything.

The God of Darkness took you, unknowingly to the other Gods, and brought you here for a very important purpose. The God of Darkness was supposed to be the one explaining everything to you, however we encountered troubles in capturing your soul. As he is currently busy, he left me to explain and assist you. We have an hour to converse, please ask your question, mortal]

"Why am I brought here? and why me, to be exact?"

[To answer your first question, the God of Darkness transferred your soul with the goal of asking for help, which is to be specified after you ask all of your other questions. As for your second question, compatibility between the body and the soul is important, and we only have one host to store a soul in, and out of the billions of souls, yours is the most compatible, and also the most capable to handle the job. Do you have any other questions]

"Rather than a question, I have a request"

[Speak your thoughts]

"After telling me this job, or specific whatever the God of Darkness wanted me to do, tell me everything I need to know"

[Affirmative. Proceeding, your job is to help a human named Cale in saving world 367, for further information, I shall transfer the world's information, as well as the timelines needed for further understanding, and the memories of the body you are to reside in. Please relax]

In a single moment, his mind became a vessel, flooded with the memories and information of the world, granting him a profound understanding of the past and a unique perspective on shaping the future.

".....I see. What do I get for accepting this mission?"

[Your reward for accomplishing the mission is to be discussed and decided later on, for now, as compensation for taking your soul into this world and forcing you to take a mission, the God of Death gave me the ability to fulfill 3 of your wishes. Start thinking of them now, mortal]

"Do I have to state my wishes right now? or I could do it later"

[...forgive me for rushing you, your wishes has no expiration, you could tell me your wish any time anywhere]

"Will you accompany me in that world?"

[Of course, I have been tasked to assist you, and that lasts until you take your last breathe in that world. Please inform me if you wish to enter the world, if not, do whatever you want, we have 30 more minutes to idle around]

"...never mind, let's enter the world"

[Please wait for a moment]
