The melancholy of Suzumiya Haruhi-chan / Tanigawa, Nagaru

"Fueled by her now-legendary melancholy, the absurd adventures of Haruhi-chan continue, utterly unbound by the laws of reality! Cozy up under the kotatsu with Haruhi-chan and the Brigade--for as long as you like. Take flight with Haruhi the superhero as she swoops in to save the day...on her own terms! Bask in the obligatory swimsuit chapter! All leading up to the final chapter!"--Back cover.

Suzumiya Haruhi and the gang deal with swimming suits, a dangerous Celestial, and a new student organization.

"But it's just as much a delight to finally have someone willing to fight against the tyranny of the straight man . . . Or so one would hope. With Yasumi Watahashi now on the scene, Kyon's straight man game is soaring to new heights, Asahina is going crazy, and Haruhi is acting more like a Brigade Chief than ever before! And what of the feline-ified Kuyoh at Nagato's house--when Kyon faces off with her, what could his fate possibly be!?"--Back cover.

"Is it too much to ask for a little peace and quiet around here? I mean, it's cool that my old pal Sasaki showed up out of the blue, but now Mori-san's blackmailing Tachibana, Fujiwara's being a general pain in the butt, and Kuyoh--who's a cat for some reason--is clinging to Kimidori-san. Amid the chaos, the SOS Brigade's final line of defense and the individual most responsible for my own sense of well being, Nagato, is downright...cheerful?"--Back cover.

"Koizumi and his fellows from the Agency are constantly cooking up ways to gently (*ahem*) encourage romantic feelings between Kyon and Haruhi, but Koizumi's holiday board game tests the very limit of Haruhi and Kyon's acting abilities! Thankfully there's plenty more holiday fun to be had, including the many fine offerings of autumn and the dawn of a new year"--Back cover.

Whether solo or with the SOS Brigade, Haruhi-Chan takes any opportunity she can find or invent to add fun to any situation.

Haruhi loses her hairband, invents a new card game, and encounters an older version of Mikuru.

Haruhi and the SOS Brigade celebrate April Fool's Day and look for new recruits.

When Haruhi-chan suddenly disappears, the members of the SOS Brigade get a moment to rest, but it is not long before their fearless leader is back and planning more outrageous activities for the group, such as making friends with demons, holding an eating contest, and organizing Setsubun festivities.

Haruhi Suzumiya comes up with new activities for the SOS Brigade, including going to the beach, taking scenic hikes, and moongazine in bunny-girl outfits.
