Counterattack Daily Life

Inoue Sora originally thought that after time travel, he, who was an orphan in his previous life, would have a warm family and live a different life. However, he never expected that just after time travel, he would have a protagonist's start with a sister, a house, and both parents dead. Fortunately, it seems that God has not abandoned him and has given him a system that allows him to counterattack in this abnormal daily life. This novel and its characters are purely fictitious.
