In India where our main character Akash lives for 28 years of regular office worker doing 9 to 5 job met with an accident by our favourite truck kun and by stroke of luck met the ROB . He asked Akash to say 3 wishes as no negative karma was present in his previous life .
As a regular reader of these kind of novels and fanfictions Akash was always ready with the options he want to choose so he can have life with many beautiful wives to live a life of passion .Akash also have a mindset of not caring for anyone except himself and oopai girls.
So for first wish he asks for word travel system with all other functions attached. Next he wants to reincarnate as Nobita in Doraemon anime at age of 17 and the main plot to start at the same time. Last but not least Akash asked to have body with unlimited potential and gain powers more easily.
ROB wants to accept all of this as it is not too much but for sake of fun and entertainment he adds a condition that he can not travel world's that easily .
If he want to go to other world he has to live at least 100 years in that particular world as well as there will be many more anime series world merging with this world in the further time so he has to be prepared for the surprise.
Seeing that it was a reasonable condition you agree to it without giving much thought. Now not having anything else to say Akash ask to be teleported to random world to start a new begining.
So, lo and behold our main protagonist starts to get sucked into a wormhole to get isekied....
