Nobi Nobita's Road to the Gunslinger

What, I became Nobi Nobita! Yes, it's still good in the everyday world. Na*, it's not the world of Doraemon, it's a foreign continent! How can I, an otaku, survive, 555? Even if I go to another world, I must at least play a more powerful role! No, Nobi Nobita is pretty good. He is known as the leader of the parallel universe, the pirate king, the father of the dinosaur civilization, one of the three silver swordsmen, etc. This novel and its characters are purely fictitious.
