Isekai no Bokujou wo Souzoku Shimashita: Star Stream Farm

Shizuru was exhausted and felt cornered at his exploitative company. One day he inherited a farm in another world from his beloved grandpa! On top of that, when he travels to the other world, he somehow turns into a girl...!? The start of a gender-swapped transfer to another world, a fluffy slow life with cute animals!!
