I Want to Make Komagome-kun Cry

Komagome has infiltrated a human high school in order to become a full-fledged demon. His mission is to plunge his target girl, Shinagawa, into despair and drink her tears. However, Shinagawa is always smiling and never cries at all. Far from it, whenever Komagome sees her smile, his heart won't stop pounding...?! A heart-throbbing romantic comedy between a clumsy, pure-hearted demon and an oblivious girl! (Source: FaMH Entertainment, translated)
