20th Century Boys (manga)
Spice & Wolf (light novel) 17 volumes ~ 50$ + tax + shipping. Read in Japanse only.

Seen some is more like a "Watching what is currently airing in Japan" section. I don't include titles I'm actually watching right now since I finish series rather fast. Things I drop after a few episodes don't deserve to appear here or elsewhere in my lists. Needless to say the ratings in this category if present are not final, but they do reflect my obsession with the series, instead of marking my emotional attachment and the overall quality like in Seen All category.

A little about my likes and what you may find in the comments. I value Drama above other genres, then Romance and Comedy, so I may be am a little biased; overrating series that fall under my interest. Good characters make me feel their pain and their joy, so drama means a lot to me. There is one theme I don't like though - cyberpunk. I usually avoid those. Comments mostly contain my impressions and/or recommendation to those who have yet to see the series so I've tried to keep spoilers out or cover them in black. Feel free to PM me if you have a suggestion, criticism or your own recommendation.

Please note that hentai titles are rated in comparison to the other such titles and not the regular anime.

Oyasumi Punpun (manga) Masterpiece Soul crushing... yet realistically ugly and beautiful at the same time. This was a lot to take in. All I felt was numbness in the end. Not going to read again any time soon. February 2014.
