(As to the background of the story of "The Disappearance of Nagato Yuki-chan," creator Puyo's "Haruhi Suzumiya" spinoff comedy manga, please read my review of "The Disappearance of Nagato Yuki-chan: Vol.1.")
Haruhi Suzumiya, heroine of the original books, finally appears in the second volume of "The Disappearance of Nagato Yuki-chan." Yuki and Kyon, two North High school students, encounter a Kouyouen high school girl Haruhi Suzumiya, who is found collapsed in the street. Apparently the eccentric girl was "doing a stakeout" to capture Santa Claus all through the night before.
Haruhi, who declares she intends to find aliens, time travelers and espers, comes back a few weeks later (with shivering Koizumi in tow) to join Yuki and Kyon's literature club - even though she is not even a student of North High. And it seems Haruhi is also interested in Kyon.
Overall, the second volume of "The Disappearance of Nagato Yuki-chan" is more romantic in tone than the previous installment, with an emphasis on the relationships among three characters Yuki, Kyon and Haruhi. This delightful comic that started as a spinoff of a hugely popular light novel / anime franchise now tells its own tale that is a perfect blend of comedy and romance.
A few comments on the book's "Valentine's Day" episodes. Probably most readers are familiar with this custom, but in Japanese culture, especially among teenagers, there is a custom in which on Valentine's Day women give gifts of chocolates to the men they have a crush on. For Nagato, who is clearly in love with Kyon, this is something important, but how can a timid girl like her pull it off? See it for yourself.
This is a sweet romantic comedy with likable characters and some nice humor (including a hilarious sequence of Tsuruya-san and Asakura-san debating over cuteness of Mikuru and Yuki). Manga creator Puyo has become more skilled as a storyteller with a few clever twists to the familiar romantic comedy's conventions. Recommended.
