I don't remember if I said this before, especially because of how seemingly outlandish the comparison is, but the facial expressions sometimes remind me of Jhonen Vasquez.
I appreciate Shushu armpits on the front cover, but I feel Takemura-sensei draws them a bit too much like Yabuki-sensei, and they're kinda featureless compared to e.g. the work of Horikoshi, which somewhat ironically doesn't aim for overt eroticism. Also like Yabuki, Takemura draws feet kinda weird, which is unfortunate when quite a lot of the femdom fanservice ends up being foot-focused. I'm reminded a lot of 大嘘, actually.
Anyway, plotwise this volume kind of abandons the teaser at the end of Volume 1. We do encounter the Shuuki girl who may or may not be Yuuki's sister, but for the meantime the issue is the mere existence of human-like Shuuki, which prompts the government to have all its soldiers band together going forward, which in turn kicks off a small tournament arc to settle differences between the Seventh and (newly introduced to the reader) Sixth squads. More significantly, the Sixth Squad is home to Himari's sister, and there's bad blood between them, so the main idea is character development for Himari in this arc, kinda unfortunately sidelining Shushu. Did Yuuki even get a new form when bonding with Shushu? I guess not, because he transforms from Himari channeling Kyouka's ability. Digging the new ninja form, even though it maintains this super Japanese idea of "increased speed meaning decreased strength," which is not how force is calculated, but whatever.
I flipped through the volume briefly before actually reading it, and didn't see too much that stood out explicitly as sexy, I guess expecting something like two-page spreads of ass or titties. The fanservice in this volume starts off a bit... well, I don't want to say "light," but at least clothes are mostly kept on; the first "reward" Yuuki gets in this volume is clothed ballbusting by Kyouka. One can understand why VIZ doesn't pick up lewd Jump manga! We segue pretty soon into Kyouka grinding her naked foot on Yuuki's face, which, I think like in Volume 1, doesn't have "steam" or anything you'd expect from foot-centric porn manga (uh, n-not that I know...!). Good upskirts of Kyouka from front and back as well. Then we get Shushu and Himari nipples. Then a panty-flash (with disgusted facial expression, shout out to 40hara!) after Himari first uses Kyouka's power. Then she forces the "reward" to end by removing her skirt and sitting right down on Yuuki's face(!!). After that it's mild nudity by Himari's sister and a newer Sixth Squad girl with fatter titties. Oh wait, I skipped Himari showing her boobs to Yuuki for another reward! Kinda weird, because they look big-ish when she's pushing them up, but then she's shown as flatter to contrast the newly-introduced sleepy titty girl.
Himari's power turns out not to be just turning her arms into weapons, but rather the ability to copy other powers. Her sister has a time stop/rewind power with a DIO-esque time limit. Yuuki's sister is shown to juggle several Mato Peaches, suggesting other not-Arrancars will also have several powers. So the ability system is already kinda broken lol
Yuuki's sister is hot. Himari's sister is also hot. Other new girls are hot as well. I'm interested in the dragon(?) girl at the end of the volume, with the tan muscles.
