Naruto: I Have an Older Sister

You shouldn't wander around on a rainy day. One wrong turn, and I ended up in the world of the Hokage, as the orphan of the Fourth Hokage. Fortunately, I got a System. I can get stronger in an instant, and showing off is eternal! The System's power is beyond your imagination, but it has one strange quirk: it likes to force its Host to build a harem and collect girls! Hinata: "Who says I'm your wife? Don't you dare!"
