(Crossover + Multiple Heroines + Daily Life + Playing the Fool While Hiding His Strength)
After a plane accident, Si Han unexpectedly found himself in a very special world.
There, he discovered that characters who had previously existed only in movies and TV shows were actually living in this world.
So, drawing on his knowledge of the plot, he first used Lu Xiaoqian's silly girl to get his hands on the other spare units.
Then he used a spare unit to visit the blue robot cat in Sakura Country, buying up all sorts of future gadgets from its spare four-dimensional pocket.
When he started traveling through time with the time machine, a configuration error sent him to another world instead.
In the Naruto world, while stargazing, he saw Kaguya beating up Isshiki, and then she latched onto him.
In the Ultraman Tiga world, he rescued the lost girl Camilla and gathered a bunch of brothers to claim territory as their own. Who knew Daigo would still be turned against him by Yuzare?
In the DXD world, that flame-like hair left Si Han utterly captivated.
At that moment, he decided he would become the king's man!!!
For plot reasons, the characters will be separated for a while early on, so don't worry. There will absolutely be no angst.
Once Si Han becomes a Saint, he'll create a separate world for everyone to live in. That's probably when we'll get things like Kaguya's Ten-Tails fighting Camilla.
Story arcs: Naruto + Ultraman Tiga + DXD (ongoing...)
