Become a Demon from a Fake Succubus

Nocher was sold to the devil for two gold coins. Until the end of three years, you can be recommended by the devil and become a candidate for the new devil... Wait? Can I really live that long? Also, is that kind of thing real or fake? ! "My child, put on this ring and start your new school life..." "Mom, you will lead me to a bright future, Right? " "Hey." "Hey what do you mean?!" [Humans are the best delicacies in the demon world, and pretending to be a demon to enroll in school will not cover up your scent. Please host be patient and patient. … "Mom, can I drop out of school..." "Mom is a little hungry." "Mom, I love going to school... (Crying voice)" [It is detected that the host has entered the Demon Academy and obtained the certificate of bravery - your panic will not be seen by the demon. Ah... Not bad... Thankfully these demons have never smelled humans... [You have completed the familiar summoning ceremony. Your pure non-demon blood has allowed you to successfully summon the special familiar - Sullivan! But it wasn't until this day that he felt something was wrong... I look so ordinary... Why can't I be quiet in life... Letters of confession, special care, shy escape... So you always thought my scent was that of a top succubus? !
