History YMMV / RootLetter

* MagnificentBitch ("Princess of Himegamori Forest Route"): [[DrivenToVillainy Shiori Yoshioka]] and her sister [[VengefulGhost Aya Fumino]] were the [[RapeAsBackstory abuse victims]] of their father, Profesor Naoki, who sought revenge on him. After Aya killed herself because of Naoki, Shiori became his next victim with her classmates joining in. Losing all hope for herself, she wished to be reborn, calling Aya's spirit to possess her and get revenge. Succumbing to her anger, Shiori joined Aya in [[BestServedCold a master plan to bring the most pain to their targets]], first killing their father while disguised as a nurse and overdosing him, then deceiving and killing her targets while leading Misaki Murakami and Takayuki "Max" Nakamura into learning of the abuse to guarantee the survivors won't get away. Shiori, secretly wanting to be stopped, guides Max into freeing her and Aya from their torment and turns herself in to pay for her crimes.

** "Cursed Letter Route": [[spoiler:[[OurGhostsAreDifferent Aya Fumino]] was once a brilliant young woman who, after her death, became a [[GhastlyGhost vengeful spirit]] tormenting others out of fury of dying young. Aya used a curse letter to hex her receivers and killing students in her former class and then [[AndIMustScream trapping their souls in her world]]. A ritual was performed to keep Aya in check by using her as an alias to a random pen pal to appease her soul, but when Max broke the ritual by investigating the truth of Aya, Aya's spirit broke free and began killing again. Realizing she's bound to Shimane thanks to Max's letter, Aya decided to trick a former pen pal of hers into destroying the letters for her, before killing him afterwards and leaving Shimane to spread her curse all over their world.]]

** "Princess of Himegamori Route": [[spoiler:[[AbusiveParents Professor Naoki Fumino]] is [[VillainWithGoodPublicity seen by the public as a respectable man]], but underneath is a depraved abuser. Sexually abusing his daughter Aya for years while using his position to hide it, when Aya died due to his treatment, Fumino decided to target his other daughter Shiori by tricking her, using his wife's condition to have her move in with him, before sexually abusing her as well. When a number of her classmates found out what happened, Fumino decided to let them abuse Shiori as well for many years until graduation, laughing away believing he got away with it for many years until Shiori and Aya returned for revenge.]]

* ValuesDissonance: In the "Cursed Letter" ending, a boy mentions that he got the nickname Lettuce from his friends for being an herbivore. This references the Japanese concept of herbivore men, or male individuals who make friends with the opposite gender instead of exclusively the same. Not only is this weird by other countries' standards (as he's the age to try to befriend or date women), but it's even been dying out in Japan, making the existence of a character like Lettuce being increasingly less likely.

* MoralEventHorizon: The Last Answer Epilogue for "The Princess of Himegamori Forest" path reveals that, in that timeline, [[spoiler:Professor Fumino sexually abused both Aya and Shiori until the former killed herself and the latter was driven into despair. Even worse, when three of the guys in the group of friends caught the professor abusing Shiori, he bought their silence by letting them abuse her too]]!

* AntiClimax: [[spoiler: The True Ending, where everybody finally met "Aya" for the first time, due to her simply appearing in front of everybody without any sense of Foreshadowing, and the plot is majorly focused on her friends than her]].

* DesignatedHero: Most players have a hard time viewing the protagonist as the hero since he pushes people's buttons the wrong way sometimes and talks like a jerk when he called on Aya's ''friends'' by their nicknames. But others agree that the plot won't progress much if he didn't do what he had to do.

* MagnificentBitch: The True Ending happened pretty much because of a BatmanGambit set up by [[spoiler:Shiori]] as she knew the 11th letter would lead Max to try and find her.
