Annoyed that there weren't any translation notes here. I can't speak for the rather nonsensical part with the announcer calling the spectators "evil beasts" because I haven't seen the raws (though it makes me wonder if there was an untranslated pun there), but I do know that the "Fighting Yowai" comment of the name being "half cool, half-uncool" makes zero sense without noting that "yowai" means "weak" (and by contrast "tsuyoi" means "strong").
Anyway, this manga is sort of cute, but not amazing. Unless a lot of the humor is being lost in translation, it mostly reads like kind of a mediocre newspaper comic strip so far. I'll have to watch Osomatsu-san someday, though...
