Kōsuke's plan succeeded. He finally defeated his younger brother! Kōsuke wanted to look for his sister to celebrate, but not only him, but Hoshi also disappeared! Oh my god! My cute sister and special brother are in another world. "(? *),"What should I do? What should I do? I'm looking for you online, it's urgent _ (: _」 ∠) _!! Today, Saiki still wants to be an ordinary person — if he wasn't sent to this strange world by a garbage system and Hoshi. In order to support himself, they have to turn on farming mode. An author who doesn't know how to farm isn't a good ninja! Even if he's just an "ordinary person" in another world, Saiki would be satisfied — but when an Uchiha wants to steal his sister …Saiki takes off his goggles — it's time to let them know how powerful I am. What should I do? If not careful, he'll dominate the ninja world.
