It's like Xebec, who was responsible for the wreck of To-Love-Ru's first season followed by a more 1:1 MOTTO, just saw the story, thought it was meh and decided to make every episode like it's part of another anime. It's trope bingo here, every episode goes for what normally is an anime's whole concept, a memory loss, teacher x student, cat girls, crossdressing girls where the one doing so looks suspiciously like Tomo-chan, manga convention participation... How the mighty have fallen. One good grace is that the characters are at least more consistent, no more out-of-character moments from people like Uzui turning righteous or Himegami suddenly becoming too passive in any interaction. Though don't celebrate since it doesn't really amount to anything and for whatever reason Takeru lost his glasses between seasons and we never find out how that happened. Remember too how he has no idea about his power? Yeah, that's also missing here. Remember his harem? Well, the season's more an ensemble so it really doesn't get any attention whatsoever. Only 3-4 have it and even then most of it are just moments than the focus.
What really stings, however, is that it's like this season KNOWS it's actively stepping away from the story. The opening stinger montage is a shpeal spoken by one of the characters and while it seems aware of the main point, the villains it alludes to have been reduced to nameless NPCs who're just causing havoc for the sake of it rather than the world conquering villains alluded to throughout S1. The opening itself also seems aware of its continuity yet none of it's part of the season. The only episode that seems to be canon is the final one but even that one acts rather oddly about it's validity. One thing that is consistent is the fanservice, so if that's appealing and you find To-Love-Ru's art style amazing, this will satisfy.
It's NOT BAD, but if you were curious about the deeper, darker plot, this won't due. Only episodes really worth mentioning being eps 1, 6-7, 8-10.
