Infinite Robbery of Life

A mediocre young man accidentally came to the infinite world. Here you have to work hard to survive, as long as you do one thing and be better than others. And he gained the ability to do other people's abilities (fog). Accelerator's vector control? It looks good, let's use it first. Emiya Shirou's projection magic also looks good, so let's use it first. Zima's fbjasbfoa, okay, I will get the power of your realm when I become stronger. All in all, this is a serious story full of positive energy, joy, and joy.
