Beast Control: I, Dan Fox, Was Contracted by Ellie

[Developing flow + sweet daily routine] My name is Shenyue, I was originally lying in the arms of Sister Zi Changzhi, but I accidentally traveled to a magical world where everyone can control beasts! In a daze, he turned into a cute little pink fox! Do you think I can only act cute and coquettish? Relying on the support of the pink fairy sister who contracted with me? Nonono, I am a fox who has awakened the system! ... Needless to say, she, Aili, looks so cute! The key point is that this pink fairy lady, under her angelic appearance, actually contains a pure and kind heart! In order to prevent her from suffering any further losses, I decided to stand up and protect her! I swear! I really want to protect her, not just because she feeds me fried tofu every day! I'm not that superficial! ... Well, my name is Ellie, and my beastie is very... Cute? Bad? Fierce? No matter... Since I got him, I can't raise other beasts because they are scared away by him... He is very domineering and does not allow strangers to approach me... He is very cunning. He has to be held by me every night before he will sleep. At first I resisted, but later... In the end, am I the master, or is He the master... Also... Who is the shadow?
