Binankazura no Niwa

There was a strange person I met in my childhood. When I met him again as an adult, his appearance hadn't changed at all... He's a zashiki-warashi who brings happiness. A heartwarming love story of an office worker and a tsundere zashiki-warashi. (Source: Houbunsha, translated) Note: Zashiki-warashi are youkai that live in parlours and storage rooms and pull pranks. Seeing one supposedly brings good luck.
