Manga: Inside Mari

Inside Mari (Boku wa Mari no Naka) is a Manga by Shuzo Oshimi (author of Aku no Hana) and tells the story of Isao Komori, a recluse shut-in with no social life whatsoever who spends most of his time playing video games. He is also in love with a young schoolgirl he usually sees when he goes to the convenience store to buy food, but since he is too shy to talk to her, Isao prefers to stalk her while she is walking home. Then, one day, he suddenly finds himself in the body of Mari Yoshizaki, the very girl he is so fond of stalking.

The story operates as a deconstruction body swap stories in general, by showing that such event, in case it really happened, can be utterly terrifying.

Inside Mari can be read on Crunchyroll


Provides Examples Of:

  • A Date with Rosie Palms:
    • A pretty graphic interpretation at that. It ends with Mari apparently calling Isao.
    • Later again with 'normal' Isao.
  • All Men Are Perverts: Isao as Mari is subjected to this often.
  • Ambiguous Disorder: It's implied that the real Mari may have one of these, as when Isao-as-Mari tells Mari's mother repeatedly that he is not Mari, she responds with a somewhat strained smile and gives Isao some medicine to take.
  • Ambiguously Gay: Mari, who purchases dirty magazines full of girls, rejects every boy who asks her out, and who is implied to have been the one that kissed Yori.
  • Bat Deduction: One of the girls in the school, Yori Kakiguchi, correctly deduces that someone else is inside Mari's body.
  • Big Damn Kiss: Isao-as-Mari to Yori.
  • Bitch in Sheep's Clothing: Momoka seems to be this.
  • Body Snatcher: Isao is this, but he doesn't really remember how it happened.
  • Calling the Old Man Out: Isao-as-Mari does this to Mari's parents after they begin viciously arguing over Mari's not going to school and end up verbally attacking one another.
  • Cassandra Truth: Isao-as-Mari to both Mari's parents and to himself. Only Yori knows that he is not the true Mari. Played with in reference to the other Isao, who pretends to believe Isao-as-Mari in order to keep Mari coming to spend time with him.
  • Caught with Your Pants Down: Isao catches himself doing it. Isao-in-Mari's-body walks in on himself masturbating on the toilet, after being aroused by Mari's body. He then tells himself to continue while he's watching. It's a really weird situation.
  • Covert Pervert: Mari is revealed to be this. She was secretly buying porn magazines that were being sold by Isao at a local bookstore.
  • Despair Event Horizon: Being kissed by a boy becomes this to Isao/Mari.
  • False Friend: Momoka and her group seem to be this to Mari.
  • Foreshadowing: When Isao-as-Mari gets a call from Mari, the voice he hears crackles strangely over the phone. Later, it's revealed that it wasn't Mari at all; it was the other Isao, recording his voice on his computer and changing the pitch to make himself sound like Mari, so that Isao-as-Mari would continue visiting him.
  • "Freaky Friday" Flip: Another trope that is deconstructed thoroughly throughout the story. For the main character, the change is mostly terrifying. He often doesn't know how to act when Mari's friends are around, and is often afraid that he will ruin her social life. This trope is later subverted when it is found that Mari is not occupying Isao's body.
  • Friendless Background: Isao and Yori.
  • Gender Bender: Deconstructed. The main character is often scared with how different Mari's body is from his. He also feels guilty because, in his mind, he feels like he is stealing Mari's body. This is specially evident when Isao has his "first" period in Mari's body.
  • Incorruptible Pure Pureness: Yori and Isao initially see Mari as this. Naturally, the whole story is a Deconstruction.
  • Jerk Ass: Isao is a hikikomori who deliberately lies to his family about his life in order keep them financially supporting him. He tells them that he is attending college, but in truth he spends his day playing video games and seldom leaves his home.
  • Loser Protagonist: Isao.
  • Man, I Feel Like a Woman : Subverted. Isao does not take well the fact that he is in control of Mari's body, and can't even bring himself to look at her intimate parts. He eventually gets to look at Mari's breasts, though.
  • One Steve Limit: Yori's elder sister is also named Mari.
  • School Idol:
    • Mari, prior to her possession by Isao, was one of these. She was a popular, straight A student who was respected by her classmates. There are hints that this might just be a facade she puts in order to interact with others.
    • Isao wanted to be this during his High School years, and thought that if he became a model student, people would flock to him. His hopes were shattered when, after becoming a very good student, he found himself lonely and with no friends. This led him to quit school altogether and become a shut-in hikikomori.
  • School Girl Lesbian: Yori feels like this towards Mari. This is also the reason why she holds Isao with utter contempt and yet still decides to help him return to his body.
    • It's also implied that Mari might be this for Yori, as Isao-in-Mari's-body kisses her and then later comments that his body felt as if it was moving on its own. The real Mari also purchased dirty magazines targeted at straight men (although all of the mags formerly belonged to Isao, meaning that her buying them could possibly be due to her Stalker Without A Crush tendencies toward him), and rejected any boy who asked her out.
  • Shared Universe: With Aku no Hana.
  • Shout-Out: At the very beginning, Isao can be seen playing Dark Souls.
  • Spotting the Thread: Chapter 42 ends with Yori noticing Isao saying something that only Yori and Mari could possibly have known.
    • Happens later on when Isao as Mari kisses Yori, and states that he felt as if his body was moving on its own.
  • Stalker with a Crush:
    • Isao is this at the beginning of the story. This is NOT played for laughs.
    • Stalker Without A Crush: Mari is later revealed to be this towards Isao.
  • Wham Line: "Let's lie down here together again sometime." The reason it's a Wham Line is because, as Yori immediately realizes, Yori never told Isao the exact words Mari used when they laid down together in the nurse's office. Which means there was no way Isao could have known what he just said.
