Unofficial response: (Please wait for an official response by a staff member)
Hello there! The last editing admin can be found on the Special:ListAdmins page, and it turns out it's Nemui hime, back in 2014. However, if you want to adopt this wiki, you'll need to edit there for a week, building the wiki. Also, I've noticed you have made another adoption - since you can only adopt 1 wiki at a time, you'll have to choose between these two. :) Joey(talk)
As Joseph said, you can only adopt one wikia each month, and you have just adopted Yahari Ore no Seishun Love Come wa Machigatteiru Wiki. Please feel free to request another wikia in mid-March. -- Wendy (talk) 01:37, February 25, 2016 (UTC)
