Since the tender age of nine, Hayate Ayasaki has busted his behind at various part-time jobs to support his degenerate gambler parents. And how do they repay their son's selfless generosity? By selling his organs to the yakuza to cover their debts! But fate throws Hayate a bone...sort of.
While cleaning house, Hayate and Maria stumble upon a heretofore unmentioned, enormous jungle-themed sauna, and promptly get lost in it. After that hot, steamy adventure--complete with misplaced articles of maid clothing--it's time to cool down, as Nagi tries to cure her insomnia with a dip in the mansion's equally massive pool. Too bad she can't swim!
My least favorite characters are Yukiji Katsura (because she's a lush) and Kotetsu Segawa (because he has the hots for Hayate). This volume features the lush, so it loses a star.
While this volume gives us an experience with both a pool and a sauna (and neither one is particularly vacationy), this volume was enjoyable for the introduction of a new character with her head in the clouds.
Fumi is a new student at the academy where most of our other characters attend classes, and as she encounters some of our series regulars, she gets some odd ideas. Her imagination is outsized to her body, but she's well meaning and seems to have big goals. I hope there's more of her in some of the books I haven't gotten ahold of yet!
Also in this volume (aside from the previously mentioned unvacationy sauna and pool stories) is Hinagiku trying something new to find love and Nagi learning a lesson about not throwing things away too quickly.
The Nagi story was actually very sweet. She gets it into her head that she wants an RC car, but once it arrives, she keeps finding learning to make or use it is too much work for her. If she can't do it immediately, she loses interest. But that tendency to discard stuff quickly comes back to haunt her and, while funny, also makes her more seriously consider her impact on the things around her.
