Apparently these are the most obscure TV anime I've seen: Android Ana Maico 2010, Chance Triangle Session, Generator Gawl, Getsumen to Heiki Mina, G-on Riders, Izumo (the TV version not the hentai), Kurogane Communication, Lovedol, Next Senki Ehrgeiz, Platonic Chain.
Most of them aren't particularly good but I enjoyed Gawl and Kurogane Communication somewhat. Gawl had something good going on but the ending felt rushed. I enjoyed the early parts of Kurogane when it was post-apocalyptic SoL but then they tried for some serious drama and that didn't really work. Izumo is awful but it's kind of funny bad, Ehrgeiz is just boring bad.
>>279972932 (OP)I didn't watch it myself but this one of the most popular shoujo anime of all time.
>>279973067Watched Ginban Kaleidoscope, it was pretty decent. Saiunkoku Monogatari used to be somewhat popular but nobody watches it nowadays.
