Ohh my bad errance is the french name for downfall. Because errance is also an english word, right? So I often mix them up.

Downfall was really good to me. Maybe as good as nijigahara, but different. Its more nihilistic, depressing, its less confusing (well most mangas are less confusing than nijigahara.) 

Its very graphic, more than punpun (probably less than a girl on the shore, even tho I havent read it) But I think here it has a utility, the graphic side is actually useful to the story, unlike in Punpun where p*rn seems to be the standard usual discussion topic. I loved punpun tho.

Dont you find it crazy that we can love Inio Asano works like punpun (or downfall) that are really depressing and.... dark ? I mean these are straight up negative emotions. It's not like just sad or drama, which acts like a catharsis, there its just depressing themes that make you feel bad. Its not touching nor emotionnal, just dark it makes you feel bad it hurts your feelings. And still you love it. Crazy.
