In the future, teen gangs rule the streets with high tech powered skates called Air Treks. Our hero Ikki, is one of the toughest kids around, but he's no match for those gangs that use Air Treks. He stumbles upon some skates for himself and naturally, he skates extremely well and is on the rise to become one of the best skaters ever. He also happens to live with 4 hot bodacious sisters (no relation) so plenty of FanService & comedy is provided here. This show surprised me a lot with the great animation and entertainment value. I think if you enjoy shows like Eureka 7 & Love Hina, you'll definitely enjoy this series.
This has got to be one the best animes I have seen, and believe me I've seen them all the way from Neon Genesis to FLCL. Its fun and refreshing to see great anime formula's with rollerblading as the central theme instead of demens and people with incredible and unexplainable powers. Not being a sports fan this says a lot coming from me. Try it out, and give it a chance. I know I did and I am eagerly awaiting the second. That is if people stop renting it >_<
