- Accidental Pervert: He meets Katsuragi... when walking on him and Souma doing it.
- Aloof Big Brother: To Mitsugu, though they get better.
- Bishōnen : So very pretty.
- Bi the Way: While he says he's uninterested in sex and wants to focus on anything but that, Masataka soon starts feeling attracted to both Sakurako and Souma, much to his own shock and embarrassment. Then things start going From Bad to Worse...
- Break the Cutie: The story bends over to break the kid. It almost succeeds.
- Brooding Older Guy, Gentle Younger Kid: The Gentle part.
- Celibate Hero: How he starts. He doesn't stay like that, obviously.
- Child by Rape: The reason why Masataka's birth mother hates him. She then pretty much "sold" him to the Tagamis when he was six.
- Happily Adopted: Sorta. The Tagamis paid much more attention to Mitsugu due to his weak health, but they didn't exactly abandon Masataka either.
- The Unfavorite: He feels resentment over his younger brother Mitsugu so he often tends to act cold to him, while Mitsugu obliviously clings to him to try have his attention.
- Rape as Drama: First Souma, then Katsuragi.
- Tragic Keepsake: Takafumi's harmonica.
- What Beautiful Eyes!: As said by Souma.
- Anything That Moves: He does NOT discriminate in regards to lovers, as long as he gets something from the sex.
- Benevolent Boss/Bad Boss: Souma seems to be a good boss at first, giving Masataka a job when he desperately needed one without anyone's recommendation. He refuses to fire him despite a jealous lover recommending he do so. He treats Masataka fairly and encourages him in his personal growth, even spending time with him out of work. So despite Souma having a few perverted tendencies, he doesn't seem too bad, right? WRONG. This all goes out the window when Masataka finds out frightening facts about him. Then Souma sexually assaults him and outright rapes Masataka multiple times and blackmails him into staying in service with Takafumi's debt when Masataka tries leaving.
- Berserk Button: DON'T touch Masataka.
- Bi the Way <- -> Depraved Bisexual
- Beware the Nice Ones: He's regal, cynical, soft-spoken and polite. But please, don't cross him.
- Bishōnen: And how.

- Brooding Older Guy, Gentle Younger Kid: The Brooding part.
- But Not Too Foreign: Half-English, half-Japanese
- Cain and Abel: The Abel to Sakurako's Cain. Sorta.
- The Casanova
- Chick Magnet and Even the Guys Want Him
- Calling the Old Man Out: "Abigail... Mother... Mother has definitely-- She has...!" She has forgiven you..."
- Cooldown Hug: To Masataka, after the torture and rape deal with Katsuragi. Somewhat subverted since at first Masataka rejects him, and it's only after Souma promises to not go beyond and keeps his word that Masataka lets him do it.
- And again, he gives another to Masataka when he explains his backstory and issues almost at the end, which concludes with poor Masataka having an Heroic B.S.O.D..
- Deconstruction: Arguably deconstructs the "rapist seme" character type so common in Boys Love. Plenty of Boys Love manga try to justify or explain this trope by making the seme a Troubled Abuser, but Sakura Gari goes out of its way to show exactly how a person can come to associate rape with love, or see it as their only option when faced with losing the person they love.
- Driven to Suicide: As a kid, he thought of giving himself as Slashed Throat due to his deals with Katsuragi but couldn't bring himself to do so. Later he tries to go the Bath Suicide way after realizing how badly he had broken Masataka.
- Entitled to Have You: Before he fell in love with Masataka, he clearly disregards Masataka's personal space and gropes him when Masataka made clear he had no interest in sex. After... he expects Masataka to fall into his arms because he likes Masataka and that Masataka should accept him despite the very unsettling discovery Masataka found. When Masataka refuses him out of fear, Souma rapes him.
- Important Haircut: When he breaks away from "Abigail" he asks Masataka to help him his hair cut short.
- Love Makes You Dumb: His affection for Masataka can bring out the idiot in him.
- Love Redeems and Ladykiller in Love: For Masataka
- Really Gets Around: He's more or less a High Class Call Boy and has slept around with many people with his consent or not.
- So Beautiful, It's a Curse: Very, very much so.
- Troubled Abuser: His horribly fucked up view of love and sex comes from the truly horrid abuse he's been through.
- Yandere: He blackmails Masataka into staying with him when Masataka tries to run away. Souma poisons Dr.Katsuragi for hurting Masataka and eggs on the doctor's abused wife to finish him off.
- Loving a Shadow: Has completely idealized his long-lost love, Souma's dead mother Abigail. To the point of periodically asking Souma, who's a dead-ringer for her, to put on her shawl and let his hair down so he can sort-of speak to her.
- My God, What Have I Done?: When Souma almost goes Calling the Old Man Out on him.
- Parents as People: He isn't an evil person per se, but he hasn't been a good father to any of his children.
- Reasonable Authority Figure: Subverted: while he's not a bad and horrible person, not only his health has taken a nosedive, but he's unable to handle the family business and thus Souma is the one who does so.
- Star-Crossed Lovers: Him and Abigail
Lady Saiki alias the first Sakurako
- Bath Suicide: Everyone thinks she died like this. The truth is FAR uglier
- Double Standard: Rape, Female on Male: Totally averted. Her rape of young Souma is not played for laughs or excused in any way.
- Hypocrite: She despised Souma for being made heir when instead of her child, but Youya is not Lord Saiki's son.
- The Resenter: She hated Souma for being made heir over her child.

- Creepy Crossdresser
- Enfante Terrible: She has just turned 15 years old, but is really screwed up.
- Hime Cut
- Little Miss Badass: Very proficient with a katana when it's needed.
- Madwoman in the Attic: After an incident during a Cherry Blossoms pasrt, Youya/Sakurako was locked away in the old house, with Katou as their only caretaker and constant company, while everyone outside the manse thought s/he had died of illness. S/he only got out when a fire broke in and Terashima died.
- My Mom Will Live Through Me: Took up the first Sakurako's name after witnessing her murder at the hands of Katsuragi and Souma.
- Red Eyes! Take Warning
- The Unfavorite: Became this when Souma was aknowledged and taken in by Lord Saiki. This is what drove the original Sakurako to madness and to all the Souma abuse, as revenge for her child being shoved aside in the succesion.
- Walking Spoiler: Sorta. She appears rather early in the story, but a good part of her motivations are driven by a massive secret in the past.
Nogawa "Takafumi" Matsushita
- Big Brother Mentor: To his little brother Masataka.
- Jerk with a Heart of Gold: Harsh and rough around the edges, but basically a kind and hardworking young man who loves his baby brother. He's also the only member of Masataka's birth family that he's more or less in contact with.

- Yakuza: He gets in trouble with them, and Masataka is stuck with working off his debt... to Souma. He does keep his word and pays up. Bad thing, it still doesn't work.
- Cherry Blossoms: He likes to make charms in the shape of sakura flowers. And he gives some to Masataka before he returns home, to wish him luck in his university exams.
- Cute Shotaro Boy: Such a cutie!
- Ill Boy: Has been thrice in the brink of death. And one of them happens when Masataka is in Tokyo, so the Tagamis send him a telegram and ask him to come back home for a while.
- Innocently Insensitive: Subverted. Mitsugu clung to Masataka which caused him to reject him, but later he revealed that he was very aware of the tensions between them and even confesses that he almost wanted to die because of it. Masataka calls him foolish, but from then on they start getting along better.
- Old Retainer
- Secret Keeper: She actually did know that Souma was abused by the first Sakurako, but she kept it quiet to not tarnish the family's honor. She never forgave herself for it.
- Supreme Chef: An excellent cook, and sometimes makes Your Favorite to show affection to others.
- Team Mom: Tries to keep order among the maids and butlers.
- The Butler Did It: He and the actual Sakurako are responsible for Youya's fall to madness, but he didn't do anything besides act as Sakurako's right hand. Until the end, where he does stab Souma over Youya's death.

Dr. Tomohiko Katsuragi
- Abusive Parents: Off-handedly mentions that his mother abused him. He also has a flashback of his teenage self tied up to a cherry tree, but not many details are given.
- Bitch in Sheep's Clothing: He appears at first to be a handsome but stoic doctor. Then we're led to believe he's a shady but not really evil guy, even getting an apparent Pet the Dog moment via supporting Masataka in public. And then we get to see what an horrible person he actually is.
- Domestic Abuser: Poor Asayo
- Eye Scream: When he puts Masataka's hand inside a pot of boiling tea, Masataka is finally able to react and defends himself via throwing the pot and the tea on Katsuragi's face before running away. Later, Katsuragi is seen with half his face bandaged - including his left eye.
- Hospital Hottie: Very handsome and works as a doctor.
- Humiliation Conga: The three persons he abused the most become the key to his perdition.
- Master Poisoner: Katsuragi made his own drugs and poison, using hemlock and arsenic among other things. Considering that he poisoned Lady Saiki to death and later slowly started to do the same to Lord Saiki...
- Rags to Riches: The backstory shows him as as a low-to-mid class highschool student who lived and worked in the Saiki's Big Fancy House. When we meet him, he's one of the top doctors in a local hospital and the personal physician of the Saiki clan.

- Stepford Smiler: She seems to be a sweet Yamato Nadeshiko. The truth is far sadder and uglier.
- Unwanted Spouse: Not only it's implied that Katsuragi married Asayo just because her dad owns the hospital he works at, but she clearly knows about his obsession with Souma. And her husband cruelly beats her.Souma: "Katsuragi truly is a man beyond redemption."Asayo: "It's fine... I'm his wife... in name only"
- Fingore: Applied to him by Sakurako. For worse, she nonchalantly crushes his drawing hand
- Sacrificial Lamb
- Staircase Tumble: What follows his Fingore episode. But that's not what kills him...
- Man on Fire: This is what does him in.
- Tall, Dark, and Handsome: A very good-looking boarding student who also is a talented illustrator.
- Crazy Jealous Guy: For Souma, again.
- Knife Nut: Which he uses against Masataka - but Souma takes the hit.
- Spurned into Suicide
- Yandere: For Souma, whom he tries to stab to death.
- Alpha Bitch and Clingy Jealous Girl
- Arranged Marriage: What her dad wants between her and Souma. Souma seemed inclined to agree, but then the ending came.
- Hair Decorations: Always wears cute barrettes
- She Cleans Up Nicely: Not that Kanako didn't dress up prettily, but seeing her in a luxurious kimono note instead of a Western dress has a similar effect.
The Unnamed Maid

- Heroic B.S.O.D.: Suffers a massive meltdown upon seeing Sakurako.
- Madness Mantra: "NOOOOOOOOOOOO! Give it back, give it back, GIVE IT BACK!"
- The Mistress: What she was to Souma, though likely not by full will. We'll never know.
- No Name Given: Well, yes.
- The Ophelia: By the time we see this poor girl, her eyes look dull and her expression is vacant. She then attempts to get info about Souma's well-being after his suicide attempt and asks Masataka if he has stepped into the warehouse, but as she's speaking to him she briefly sees Sakurako around and starts screaming... The next time we see her she is smiling madly and tells Kitamura that she believes Sakurako tried to kill Souma, just like she did to her and Souma's baby. Poor, poor little girl.
