Danganronpa: Kibou no Gakuen to Zetsubou no Koukousei The Animation, Kiznaiver Recommendations
Both anime mix serious, psychological questions with weird and funny situations. They both have a mismatched group of characters being forced into hard tasks by mysterious, unknown people. If you like one, you'll probably like the other one.
Both have a cast of teens who are faced with a trial/experiment that they don't want to be apart of. Kiznaiver is more focused on the character's emotions Danganronpa focuses on violence/betrayal between characters. Both offer a psychological plot and a similar cast (though the cast of Danganronpa is much larger)
