My Sister's Name Is Haruno Sakura

My name is Haruno Makoto. You will probably know this name. I am Haruno Sakura's elder brother. Although he accidentally traveled through time and became a civilian ninja without any accompanying system, is the system as good as having a younger sister? Although I was born in an embarrassing era, I had just experienced the Nine-Tails Disaster, and the village had just escaped from the war. It was extremely difficult for me to get ahead! But instead of fighting and killing, I still hide at home with my sister and watch TV! Occasionally, she will bring her cute friends over, tsk... These days, she lives more freely than a god~~ This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
