History Manga / ShiroNoEden

* BigBrotherInstinct: Mashiro claims that her stepbrother Shuuto hates her, but he's actually quite protective of her. He goes after Mashiro on more than one occasion when she runs off from home and is distrustful of Ai, who Mashiro is fond of. Sara Sasamoto even lampshades this in Chapter 9.5 when he compares Shuuto's attitude towards Mashiro to that of an OverprotectiveDad. However, later chapters indicate that Shuuto's reason for being overprotective of Mashiro and hostile towards Ai is because [[spoiler:Shuuto has feelings for Mashiro.]]

* BeautyMark: Ai has one by his right eye.

* {{Megane}}: Masamichi.

* NotSoDifferent:
** Mashiro's attraction to the amiable and carefree Ai appears to be a case of {{opposites attract}}, but she soon realizes [[BirdsOfAFeather that Ai is lonely too]]. [[spoiler:It also turns out that they both have issues due to their mothers telling them to be "good kids." Ironically enough, they share the same mother.]]
** Mashiro and Shuuto turn out to have this as well. Mashiro is convinced that Shuuto hates her, while Shuuto hates it whenever he gets worked up over her.

Through Ai's guidance and seeing how friendly and fun the Tori ni Ko Cram School and its students are, Mashiro decides to join the cram school in her resolve to change herself and to reach out to others, and in doing so, she gradually finds herself becoming [[HotForTeacher closer to Ai]] and falls in love with him. However, in spite of Ai's friendly demeanor, it's soon hinted that he is [[HiddenDepths not-so-friendly]] as one would realize and has problems of his own that are [[BeneathTheMask masked behind his]] [[StepfordSmiler smile]].

** Ai is shown to be quite the {{jerkass}} a couple chapters into the series, though Mashiro believes it may all just be a {{jerkass facade}} because Ai is lonely.

* MoralityPet: Mashiro appears to be one for both [[JerkassFacade Ai]] and [[{{Jerkass}} Shuuto]].

* {{Kuudere}}: Ai.

* [[spoiler:SurpriseIncest: Mashiro likes Ai. Ai eventually reciprocates Mashiro's feelings. Then, they turn out to be related.]]

Third year middle school student [[PluckyGirl Mashiro Serikawa]] is [[EducationMama pressured]] by her stepfather and mother to do better in {{cram school}}, is hated by her [[NotBloodSiblings stepbrother]] [[{{Jerkass}} Shuuto]], and is [[FriendlessBackground isolated]] from her classmates because of her constant studying and her status as the adoptive daughter of the Houou Seminar Cram School's principal. She feels like she doesn't belong and constantly tells herself to be a [[WellDoneDaughterGirl "good child"]] [[HeroicSelfDeprecation or she will be hated]].

* HeroicSelfDeprecation: Mashiro. See [[WellDoneDaughterGirl "Well Done, Daughter" Girl]].

--->'''Mashiro:''' Brother, I'm sorry! For making you worry and look for me...
--->'''Shuuto:''' That was... It's nothing. I wasn't worried about you! [[SuspiciouslySpecificDenial Just now, I was just taking a walk! I wasn't searching for you!]] Don't misunderstand!

--->'''Ai:''' Good evening. You came to pick up Serikawa-san...
--->'''Mashiro:''' Brother...
--->'''Shuuto:''' You're wrong! [[BlatantLies I was just about to go to the book store!]]
--->'''Ai:''' [''notices Shuuto chose the wrong sandals while rushing''] But those are health sandles. Ladies' sandals too.
--->'''Mashiro:''' To the book store...
--->'''Shuuto:''' It doesn't matter!

* [[WellDoneDaughterGirl "Well Done, Daughter" Girl]]: Mashiro's mother always told Mashiro as a child to be a "good child." As a result, these words have made Mashiro desperate to seek her mother's approval and to be a "good child" in fear that she will be hated.

** When Mashiro meets Ai, he tells her that she looks familiar and that she's like his little sister, who is "super cute and such a [[WellDoneDaughterGirl good girl]]." However, this unintentionally only fuels Mashiro's [[HeroicSelfDeprecation heroic self-deprecation]].

* GenderBlenderName: Sara Sasamoto. This is probably a ShoutOut to his older brother Karen "Ren" Sasamoto from ''KareWaTomodachi''.

** This manga series is in the same universe as Yoshioka Ririko's previous manga ''KareWaTomodachi''.

* HairOfGold: Mashiro.

* {{Blackmail}}: After they discover that Ai does [[spoiler:CompensatedDating]] as a side "job," Shuuto tells Mashiro that he will not tell anyone about it, as it would jepordize Tori no Ko Cram School, if Mashiro agrees to quit the cram school. Mashiro reluctantly agrees, but is able to return to the cram school once Ai decides to quite his side "job."
