Tsugumomo getting serious...
Tsugu Tsugumomo leaves off straight where the first season left off and well Kazuya and Kiriha has new enemies and allies to befriend in this season all the while things are brewing with the attempt on Kukuri's life is at stake. Now before all that seriousness does arrive though, Kiriha and Kazuya for the early parts of this seasons goes go through the usual isolated amasogi spirit cases in Kazuya's school and even formed the Troubleshooters Club in order to combat these amasogi, some which seems directly a letter of war from the new enemies of this season all the while.
With all being said however the fanservice is still in this season but toned and lessened down compared to the previous season, mainly in LA's eyes due to the different direction and tone Tsugu is going for thus the toned down fanservice throughout but what fanservice there is, it's expected cliche fanservice. For LA it was "meh" alright fanservice nonetheless.
So with the serious topic of new enemies after not only Kukuri but Kiriha and Kazuya in comes the Mayoiya arc where the new enemies reside and one of the more interesting things about them as we find out WHY they're after Kukuri and their desperation and this links to their lore of being tsukogami's and once they befriend Kiriha and Kazuya by mistake and gets to know their side fo things subtlely for the audience anyways, it does give a good sense that these new enemies aren't "exactly" villains, more like people desperate to survive, just their methods aren't exactly the best.
Character-wise, we do get some from Kazuya, FINALLY, though the first season gave him a bit, this season gave him a bit more of a backbone in this regard and pretty much took charge of the Troubleshooters Club as well as other crazy antics the amasogi gave Kazuya trouble with, though it's also because some revelations have happened that causes Kazuya to take up the stage proper as a character moving forward and just wanting to help people. Kiriha is the same old Kiriha though still a tsun, it's more like this season tries to nudge the entire romance angle with Kazuya, though the more shounen elements of this season takes precedence and finally Sunao from the finale of the first season gets some proper resolutions with Kotetsu as well as her pretty much getting added to Kazuya's harem at the same time.
To this end, due to the more serious nature and this season looking into villainous tsukogami in this season, the world building of this season was greatly affected in a good way, giving us a different perspective other than Kiriha and Kotetsu and with how deep the entire Mayoiga arc goes it even delve sin the entire system and lore of the Japanese Gods and what links they have to the tsukogami's, heck it even questions Kukuri status as a goddess in GLORIOUS fashion.
The animation is the same as it's first season that of Zero-G and it looked like they stepped up a bit especially with the shounen-like battle scenes and the overall consistency of this season was pretty good all throughout. Zero-G made this second season look rather polished from the first season and it's animation was pretty consistent, either way, good job Zero-G.
The voice cast is back with a few new additions of the new "villain" tsukogami's of Arumi voiced by Riho Sugiyama, Akito voiced by Shogo Sakata and Mimane voiced by Mami Uchida. But the MVP for this second season easily goes to Yurika Kubo as Kukuri as she got her time to shine in this second season but also the returning cast like Naomi Oozora as Kiriha and even Yuuko Sanpei as Kazuya got her time to shine with how "shounen" this second season got. Overall, the voice cast like it's animation was consistent and pretty decent all round with the only exception of Yurika Kubo being the MVP of this second season.
LA said in the previous seasons review of Tsugumomo that it was scattershot with it trying to do everything, well this second season remedied it, with a focused story arc, whilst having a buildup of isolated amasogi incidents to kick things off with. The fanservice was toned down and expected to be for this season with the tone it gave off and in some ways Tsugu Tsugumomo pretty much is going in the way of Negima!...in SOME SENSE, LA will stress, as both are mild to outright ecchi harem anime that turned into a straight on shounen battle harem.
This is definitely a step up from the first season rather scattershot focus and though the villains of this season aren't necessarily evil thus diminishing the shounen aspect to a certain extent, it however helps that given the insight to the villains of this season gives an interesting dynamic and new point of view of Tsukogami's thus a MUCH more immersive world building aspect to tsugumomo, something the first season glossed over. Developing characters, world building, decent production, decent but not in your face fanservice, Tsugu Tsugumomo pretty much gave what LA wanted out a focused second season of Tsugumomo and it mostly or expectedly delivered.
