Briefly about I Just Want To Game In Peace manga:
A drop of blood saves a life. When others play games, their livers explode, and I also play games. When the dimensional storm came, a large number of different-dimensional fields appeared around the earth, and various different-dimensional creatures such as immortals, Buddhas, demons, angels, elves and so on came to the earth. But those mysterious different-dimensional fields have all become copies of mobile games. Others risk their lives, but I play games desperately.
