18+ Saki-chan wa Inma no Ko (Gasshou)

Succubus Saki-chan falls in love with, out of everyone, a monk's son, Rokuhara. Even though she tries her best to talk to him, her succubus blood starts rushing and unintentionally makes the situation rather... tempting. 'It wish I could just tell him that I like him, normally!' Where is this devilishly cute succubus's naughty love headed to...?! A full power love comedy about a pitiful succubus and a straight laced monk boy!
