Naruto: My Strategy Targets Are All Ninjutsu

Once traveling through Konoha, it was the eve of the Third War.
Fortunately, I awakened the "ninja world galgame system".
Mikami Yu, who originally thought that with the help of the system, could start the flat mode of life, found that the target of his strategy was a bit strange...
"Yu, why is your ninjutsu so much more powerful than others?"
"Well...you should chat with ninjutsu more to increase the favorability of ninjutsu. , occasionally give Ninjutsu gifts, and then have special interactions with Ninjutsu on a special holiday, and finally confess to Ninjutsu in the mysterious event inside Ninjutsu, and finally Ninjutsu agrees to be with you, and then Ninjutsu will become a master!”
