YOO same here! Ending felt so ambiguous Sniff manga is finished for a while now and anime aired +10 years ago (ish).
To add some I rly, rly, rly did I say RLY wanna see are Devil's a part-timer, Akatsuki no Yona, World's Still Beautiful, Usagi Drop, Golden Time and Monster of course. I'd ask for a reboot of Ouran and Deadman Wonderland. Still waiting for Noragami...
