Oyasumi Punpun, Bastard Recommendations
Soming of life stories of protagonist that might have turned to be absolutely normal if it weren't that his enviroment included some psychically deranged people that had bad influence on the protagonists. Both manga works with the theme of horrors that might be happening in personal lifes of some, hidden to public. Both also have very nice artwork.
Honestly they aint that similar. but they kinda give the same vibes and i feel like if you loved one youll love the other. I seriously recommend checking it out if u like bastard or vice versa.
