I'm looking for two mangas I read a while back but couldn't find my library anymore. Any help is appreciated. The first one is about a martial artist who defeated the demon king with the hero's party but the demon king cursed them. The martial artist is turned into a child, the mage is turned into a girl, the hero has his sexuality reversed and the princess became demonic/yandere. Now, the martial artist has to go with the gang to reverse the curse. The second one was about the mc in a zombie apocalypse. He found that he can level up and gains skills. He travels with a dog that also can level up and meets up with a female sniper that's has the shut in job.

I'm literally a rock.

First one should be Ore-tachi no Party wa Machigatteiru...
And I'm fairly certain the second one is Monster ga Afureru Sekai ni Natta node Suki ni Ikitai to Omoimasu.

~4400 manga completed
~1700 ongoing...
