Koakuma-chan no Kougeki! Succubus' Plan!

Synopsis

Liath is your typical girl-next-door: cute, bubbly, a little clingy... a succubus. You know, the usual. But for modern-day succubi like her who can feed off of human feelings of embarrassment instead of sucking out their life essence directly, things become dire when her boy-toy tries to give her the cold shoulder due to upcoming exams. Will he be able to say no to the plan she's got cooked up for him though? (Source: Irodori Comics)
