Fun-seeker protagonist + no romance + infinite realms + mastermind
Hoshimi Uzumaki, the eldest daughter of Minato Namikaze and Kushina, and Naruto Uzumaki's older sister, was lost amid the turmoil of war as a child and ended up living among ordinary people.
Hoshimi struggled to survive in a world far removed from the shinobi. When she was fifteen, a being calling itself the Infinite System bound itself to her, revealing the truth about this world and presenting her with a choice.
Would she turn the shinobi world into a game for an infinite-realm adventure?
The heroine is purely in it for the fun, has no romantic feelings, and will kill characters from the original story. Please take note before reading.
(The author wants to write about Hokage characters interacting in a game, not a true battle of wits. So all the scenarios are made up, and the mind games are not rigorous at all. Some rules are deliberately vague and messy to move the plot along. The scenarios exist only to serve the story, so please don't read this as a battle-of-wits novel. I bow to you all in apology!)
So far so good [note]
