Here is Greenwood Volume 2:
"Headache Nemesis" Part1-Part2-Part3
Volume 2 of the manga begins from the cliffhanger left behind in the last pages of the previous volume—the three part "Headache Nemesis". This story introduces Nagisa Tezuka, Shinobu's jealous and psychotic sister, bent on disgracing and destroying her younger brother for years of torture and defeat in their unending sibling rivalry. Nagisa kidnaps Mitsuru, in an effort to both seduce the pretty-boy, and to finally see her brother kneel for the sake of his best friend. While all of this is going on, Kazuya Hasukawa is physically exhausted and in the midst of a high fever. Shun, who was there when Mitsuru was kidnapped, finds himself the only one who really seems to care about rescuing Mitsuru. Kazuya, however, finds himself feeling guilty and hurt by the loss of his de facto mentor and friend. As such, he refuses to submit to his cold, and promises to rescue Mitsuru. Shinobu breaks into Nagisa's apartment to rescue Mitsuru (along with Kazuya and Shun), only to have Nagisa's henchmen hold a knife to Mitsuru's face. Mitsuru cuts his own face on the knife, rather than have his best friend kneel before Nagisa. This goes on to enrage Kazuya, who systematically beats up each and every henchmen in a fit of rage—only to discover that Mitsuru's face can heal within seconds of being cut. The three-part story ends with Hasukawa collapsing from exhaustion and fever, only to awake and find himself both happy to see Mitsuru safe, and distraught to realize that now his daily torture would continue unabated—that things were back to normal.
The ending of this saga is also the first time that an important plot hole is introduced. Although technically a year has passed, none of the characters have aged or moved on in their schooling. Yukie Nasu addresses this with comic brilliance by breaking the fourth-wall and introducing herself to scold Kazuya for pointing out holes in the plot of the manga — a comedic technique never used in the OVA series, but very often used in the course of the manga.
"Boy meets Boy"
The next story in the volume deals with two characters who live in Dorm room 117 of Greenwood: the masculine farm-boy Tatsuro Fujikake and the feminine Yoshiki Watanabe. The story takes place before the main storyline in volume 1. The two encounter each other in a crowded train, where Watanabe is being groped by a strange man, until Fujikake intervenes and saves him, only to find that Watanabe is actually not a girl but a pretty boy. The two part ways, only to find themselves staring at each other as Mitsuru (the dorm-head) introduces them to each other as roommates. Fujikake and Watanabe meet the other eccentric characters of Greenwood, and as time progresses find themselves becoming closer and closer. Fujikake finds himself, to his own anguish, falling in love with Watanabe. Fujikake tries everything possible to avoid Watanabe, his own roommate, going so far as to beg Mitsuru to exchange his room with the "sick-boy" in room 210 (the yet-to-arrive Kazuya Hasukawa). The story ends with Fujikake and Watanabe embracing as Fujikake admits his love, and months later as they ask a clearly uncomfortable Hasukawa to ask his older brother, the school nurse, on advice about the specifics involved in the intimacy of their relationship.
"The Japanese Summer is Here"
This story begins as the boys of Greenwood dorm find themselves dying of heat from the unending Japanese summer. This story arch can be seen more as a "filler" which the narrator and author, Yukie Nasu, admits exists to reintroduce the cast of Greenwood to the reader after the brief side-story ("Boy meets Boy"). The story reintroduces each of the boys along with birthdates and blood types as Kazuya tries to find some desperate escape from the heat.
"Poolside Man"
A handsome lifeguard finds himself inexplicably attracted to a beautiful girl, lying by the community pool, only to find later that it's a guy—our very own Shun Kisaragi.
"The True Love of a Brother" Part1-Part2
Shun and many of the boys of Greenwood have left the dorm this summer vacation, leaving only Kazuya, Mitsuru, Shinobu and the other misfits whose family problems burden them to stay. After being forced by Mitsuru to take the responsibilities of dorm president, due to Mitsuru's leaving for a mysterious family emergency, Hasukawa finds a young girl who has sneaked into the dorm. It is revealed that the young girl is actually Shun's younger brother Reina (also cursed by Shun's gender-bending genes). Hasukawa inadvertently becomes responsible for Reina's care, becoming a hard-handed figure to sweet Reina. Reina is then picked up by Shun the next day, and reveals that the reason he ran away was that he didn't want Shun's inheritance taken away due to the birth of a new baby girl—since Shun's family passes their wealth through the maternal line. Hasukawa implores Shun to heavily discipline Reina as an older brother should, only to be lost in the long-forgotten memories of his loving brother gently raising and taking care of him. At the end of the manga it's revealed that Mitsuru is actually the oldest son of a Buddhist Temple-family, and as such, may inherit it as a future monk—something Mitsuru so far seems silent about.
