[Crossover] On the Feasibility of Building a New World

After returning from a trip around another world, Senju Hashirama and Uchiha Madara are miserable every day... The ninja world has no air conditioning, no planes, no cars, and, most importantly, NO HUMAN RIGHTS! Uchiha Madara: Let's build a city! Uchiha Momoko: Let's build a country! Senju Hashirama: Let's build a new world! Senju Kazuhiko: ...Good! But ideals are lofty, while reality is harsh. Might as well cast Infinite Tsukuyomi... One thought is all it takes to level up. My name is Senju Kazuhiko. Every day, my family wants to defy heaven. Please don't ask how I feel about it, thanks! #Oh no, the ninja world's tailed-beast incarnations have kids now!# #Weren't you supposed to build a village? What on earth did you build instead?# Prequel: Link: "[Crossover] The Right Way to Break the Plot"
