Wikia just notified me that Kenichi Wiki is going to be moved from kenichi.wikia.com to kenichi.fandom.com at some point within the next few weeks. However, the old adress is still going to work after the migration. At leasts that's what staff wrote.
You can read more about the reasons for this change on Wikia's official blog: Original announcement, upate about the move.
I hope everything goes well. Why did they have to choose our wiki as one of their guinea pigs? ;_;
