Midori Wakatsuki seems to be a normal student on the outside, but her life is actually not very ordinary. Her parents died in a fire when she was young, she was separated from her older brother Tokio and placed in foster care... and at "home" she withstands her adoptive brother's sexual abuse, alongside her foster parents treating her as few more than a stand-in for their deceased daughter Reika.
Midori's terrible life starts taking a turn when, after dropping from school and while still in her uniform, she meets a man who comes from the States, asking for directions to the Tokyo Tower. She forces her way into his route, asking him to kidnap her... sort of. They end up becoming friends rather fast — And later, it turns out that the man is Tokio, her long lost brother! Tokio eventually finds out about Midori's horrifying life and decides to help her out, reclaiming custody and taking her into his household. From then on, Midori and Tokio start mending their lives. . .
Eden no Hana ("Flowers from Eden") is a manga by Yuki Suetsugu, which was serialized in the shoujo magazine Bessatsu Friend from 2000 to 2004. A year after it ended, it became infamous for having plagiarized art from other manga series like Slam Dunk and Vagabond, the discovery of which nearly ended Suetsugu's career (though she would make a comeback with her later work, Chihayafuru). This incident is also the reason why (with the exception of Peach Girl and Kin Kyori Rennai, which was released in both Italy and North America) no manga serialized in Bessatsu Friend would see the light of day in non-Asian countries for a decade after.
Eden no Hana has examples of the following tropes.
- Attractiveness Isolation: Midori's classmates wonder if this is the reason why Midori is a borderline outcast in class. It's more because of Loners Are Freaks.
- Big Damn Heroes: Subverted. Tokio actually breaks back into Midori's life right via revealing that he has been granted her custody... when she's about to be raped again by her stepbrother. While Midori's parents refuse to let him see her, that gives Midori the courage to fend off said stepbrother via a Groin Attack and reply to his calls, pretty much jumping through the window and into Tokio's arms.
- Broken Bird: Midori
- BrotherSister Incest: Midori's being sexually abused by her adoptive brother.
- Bunny-Ears Lawyer: Masamune is very flashy, but he's also pretty reliable at getting info and a good emotional support for Tokio.
- Calling the Old Man Out: "I'm NOT Reika! MY NAME IS MIDORI!"
- The Chikan: Midori falls asleep on the train and the man sitting next to her gropes her thigh. Her classmate Hashiba looks at the man threateningly and he gets off the train.
- Coming-of-Age Story
- Flower Motifs: Roses, lts of them
- Large Ham: Masamune is... bombastic, to say at least.
- Mood Whiplash: Tokio and Midori are speaking about paradise and life decisions. Tokio's adoptive brother Masamune shows up. Hilarity Ensues. And whiplash hits again, as Masamune also had the information about Midori's whereabouts.
- Ninja: Played for Laughs with Masamune.
- Parental Neglect: Midori's foster parents. See Replacement Goldfish.
- Rape as Drama: Midori's story of sexual abuse. Tokio almost went through it when in his teens, according to him.
- Replacement Goldfish: Midori's foster parents adopted her to fill in the blank left by the death of her bio daughter. Her mentally-broken foster mom treats her with relative kindness, but calls her by the dead little girl's name and acts as if Midori was the real Reika.
- Shoujo: Before it was cancelled, it ran for 12 volumes and was serialized in Kodansha's Bessatsu Friend.
- Teens Are Monsters: Midori's rapist stepbrother
- Tragic Keepsake: Midori has a photo of her, kid!Tokio, and their mother among her belongings. Tokio has one of them and their dad.
