to love ru darkness is one of the most intresting mangas i have read.
it contains a bit of everything the storyline is the main thing, at times it can be funny just watching rito get into weird situations and momos desperate attempts of suducing him. you get really stuck into the manga when the storyline comes tense when some change of events happen and you get to see some change of heart with yami.

it gets updated every month and this should be their 10th issue this month.
