Contract Book
The story is about a reincarnated boy from earth in a futuristic world with beast taming. Mc finds a system that is like a hyperbolic time chamber but it is another world. The story seems to be good but the characters seem to be 1 dimensional but the most off putting thing is the grammar. The grammar is so bad that it seems the author doesn't know MC's main gender. Author if you have seen this please fix Mc's gender.
