What even is this...as if Season 1 wasn't enough, the split-cour continues on with even more wacky sci-fi/mecha references and whatnot with Season 2. And...I've gotta say, the latter season is just as funny as the former early this year, if not a tad bit better, with more characters, some insane moments that still warrant some laughs here and there, and definitely went out with a bang (because at the time of this review, the series had already caught on and further compared to the manga source).
Assuming that you have watched Season 1 (which you should), Tiramisu Zwei continues on the pursuit that is between
the rivaries of brothers Tiramisu's Subaru Ichinose and the People of Metus's Isuzu, along with the estrange of their father, whom for some reason, has come to witness the fight against brothers (while opening unnecessary porn and censored ads in disguise for battle plans). Not to mention that now that Subaru's Durandal got a major upgrade that is Neo Durandal which is faster and better in every way, and Isuzu with the make of Subaru Beyond as means to defeat his brother, expect even more wacky stuff to take place for absolutely no reason whatsoever. And I still love it.
Major characters make their comeback, so new ones are just probably Subaru and Isuzu's dad and the commander of Metus, Cadillac, which aims to rebel against convention and go for the same reason that Isuzu hated Earth to begin with: to escape legalism. Not the best minded characters, but for it being a mindless parody, what's not to like about them?
Similar to Season 1, the same production staff under Gonzo for Tiramisu comes back again to make art and animation that is still consistent but minimalistic that is well-known with the series, and it's totally understandable for it being a short time of binge-watch, since it doesn't have to sacrifice a lot in accomplishing whatever means they have to do. The music department is the same story, just with another new great sounding OP and the new version of Season 1's ED (which includes commentary).
For a parody of its aforementioned genres, Gonzo does a good job despite the low score and waning interest after the disinterest that was Season 1. Season 2 brings new life into the series, and much from it, still gives a good impression for what it is. I'm gonna leave it to you to decide whether or not to catch-up, but it's gonna take another good chunk of boredom time to sit through everything again.
