The latest chapter is at least around ch253 or higher. The chinese scanlating team i m following just finished translating ch250. But i believe its about the conclusion to the fight between Kenichi and Kou(or whatever that guy 's name who confessed to Miu but got rejected (Owned
)) and the Shinpaku's escape from the island with Shigure's help but they are stopped by one of the fists( the host for the DoD tournament i believe). Sorry i don't know much more details.
Btw the raw for ch241-ch244 and ch247 don' seem to exist anywhere on the net as a result those chapters can not be scanlated so i don't know what happened in those chapter maybe missed something important?
