Is There Like a Skater and/or emo Anime??

for skateboarding anime I couldn't really find much but many people did recommend to others asking your pertanyaan to watch Air Gear and Eureka Seven link
link as for emo anime I'm not sure about there being anything emo specifically but there are many Gothic/horror themed animes. so anda might want to try the gothic theme.

Try [K] Project, there is a sepatu luncur, skate boarder called Yata and he is awesome! =]
