Hunter x Hunter to Resume Serialization in Weekly Shonen Jump Issue 45
An announcement was made in the latest issue of Weekly Shonen Jump (No. 40) that Yoshihiro Togashi's Hunter x Hunter will resume serialization in Shonen Jump No. 45 (on sale October 6th).
Hunter x Hunter went on hiatus in early 2006. In early July, fans petitioned for the return of HxH through a special service website called Letters to the Chairman. In early August, a source from 2ch leaked the news that HxH will be returning "sometime in October."
Also announced in Jump 40 is that volume 24 of Hunter x Hunter will be released on 10/4.
