However, some don't believe in The Senshi. They say, "I am a man of science! I do not believe in the legendary senshi!". They do this at their own peril! Once, The Senshi hurled a baby into orbit around the moon, because it looked at him funny. Would he hesitate to kill a man of science?! Scientists look funny sometimes!
This journal is said to be his holy book. It details the creation of his world, which he calls "game project that has been going on for too long". Read it and spread the gospel.
