Super strong Main characters with some comedy in the mix!
Both great shows, i recommend for all!
One Punch Man is essentially what you would get if you took Izayoi of Mondaiji-tachi and separated him from the rest of the no-names. You get an overpowered and bored protagonist destroying every obstacle in his path in order to relieve himself of his boredom while searching for a worthy opponent. Both series are entertaining and action-packed, although One Punch Man is more straightforward.
Both MCs are Super Strong
Both Series are Funny and exciting
in mondaiji-tachi ga isekai kara kuru Sou desu yo? world, the main character (izayoi) possess inmeasurable power, in one punch man, saitama looks bored all the time, so does izayoi, they're too strong and busy trying to find someone worthy enough for their power, if you like one punch man you definitely will like mondaiji-tachi
Same feels and comedy. Both have really good character developments for main male MC. Similar kind of lesson too. Saitama and Izayoi, both have power beyond humankind, they both have reached the top, and looking for someone to match them in strength, if you want to see more overpowered character then i truly recommend mondaiji-tachi, As for the story, Both shows share the same excitement.
Mondaiji-tachi and One punch man has similar male character, While Izayoi is more cocky and saitama is more bored type, they both seeks stronger opponents. Those who can entertain them to several extend. If you like one punch man, you definitely going to like mondaiji-tachi !
