Interesting New Start.
Be warned! The content in this series is more extreme than it's prequel: To Love-Ru Toraburu (2006).
To Love-Ru Darkness focuses more on Rito's other classmates/friends rather than Lala and Haruna.
As for as the product goes, The quality of this Tankobon is incredible! There is an outer-cover (the same artwork as the cover page) that I didn't expect to be there. Along with the artwork pages, the pages are of above average quality and the spine of the book is well-put together.
