When I understand the gimmick of not giving a guy a face because the reader can immerse himself in the character more that way is strange to see this atuhro do it, at least that is my opinion. Hentai is pretty good, but the last pages of the 4 volume looked rougher. Hope it gets translated, interesting how is full color, is a weird feeling to see it like this after being used to black and white for so long.
This guy basically has been copy-pasting his own work for years. The women looks all the same, the sex scenes too. If you have seen one you've seen all. Pity.
