Imigrim: Yowamushi Akuma no Isekai Ijyuu Keikaku

Junior high school student Amane lost her parents early and lives with her uncle Yuki-chan. Even though he had a faint feeling for Yuki-chan, she lived calmly for the same days, but one day, when she cut her hand with a book in the study, she summoned a devil from another world (very beautiful). Will call out. Amane has signed a contract with the devil (very beautiful) for Yuki-chan, but that's why she ended up being a "migration consultant from a different world for the devils suffering from population growth"...? *Note: Includes two extra chapters.*
