Simply, the second season is more of the first but with a few more characters. If you liked Season 1 by the end of it and could do with more shenanigans, then they delivered.
It improves on several aspects, chief of which being Minos actually appearing as prominently as a main cast member should. The new characters the season are nice additions on top. Persophone II is cute but is able to defend herself with a sharp tongue; however she unfortunately doesn’t get the limelight enough. Pino is fine, but Poporone had already taken her role long before she existed. Kyon-Kyon and Ran-Ran get the most attention of the new cast and have interesting (albeit underdeveloped) goals. Generally, Season 2 focuses more on the main cast, but having more supporting characters to spice things up is nice.
However, Season 2 hasn’t entirely improved on much else. No character changes and some jokes that have already overstayed their welcome in Season 1 — such as Jashin-chan gambling and Medusa being used for money (and fourth wall breaking if that was bothersome before) — are still just as present. It truly is more of the same, for better and for worse.
Ultimately, I don’t think there’s anything that makes this anime series stand out. It’s enjoyable enough, but I was surprised upon learning how many collaborations it’s had on top of its very successful Season 3 Kickstarter. That said, me thinking, “I would’ve thrown a few bucks at the Season 3 Kickstarter” is a pretty good indicator of where I stand by the end of Season 2.
