Our male protagonist, Junichi's heart was broken two years ago when he was stood up by a girl on their supposed Christmas Eve date. Now a high school sophomore, he spends his days in his closet planetarium and mostly spending time with his two good friends, Masayoshi Umehara and Kaoru Tanamachi.
School idol Haruka has been confessed to by countless men, all of whom she rejected. She likes cute things, but has a soft spot for puppies. Her best friend is the captain of the school's Swim Team, Hibiki Tsukahara.
The Beastmaster: She can control puppies to do her bidding, and it's absolutely cute.
But Not Too Foreign: She's a quarter British from her mother's side of the family, thus the "Lovely" in her name. It should be noted that Lovely is not her mother's maiden name, it's a middle name given to her by her British grandfather.
Clingy Jealous Girl: Out of the six main heroines, she's portrayed in most adaptations to be the most outwardly jealous whenever she sees Junichi with another girl. In the first season of the anime, the third episode of her arc is titled "Jealousy."
Covert Pervert: Haruka loves swimming, swimsuits, and girls wearing swimsuits. The latter always causes her to get booted off the swimming pool area by Hibiki.
In one Manga Adaptiation focused on her, she admits to be willing to share a bath together with both Miya and Junichi.
Cuteness Proximity: Towards dogs and Miya, despite the latter's hostility towards her, even goes as far as subjecting her to Marshmallow Hell in one episode.
Ms. Fanservice: Further enforced by her carefree, fun-loving personality.
Ojou Ringlets: A rare variant — her straight hair curls near the tips.
Perpetual Smiler: It's hard to catch Haruka without a huge smile on her face... except when you make her extremely jealous/angry.
Rule of Three: Whenever Haruka participates in the Miss Santa contest, she always wins, thus making the victory her third in a row dating back to her freshman year.
Junichi's good friend from middle school. Kaoru works at a family restaurant as a waitress to help support her single mother. Had the distinction of being nicknamed as The Nuke/Warhead of Kibitou in middle school due to her Hot Bloodedness.
A-Cup Angst: Episode 13 of Plus reveals her getting into specialized herbal bath in an attempt to increase her chest size.
Miya and Ai's classmate. Sae had only studied at exclusive all-female schools in her life until she transferred to Kibitou High in her first year, making her incredibly shy around men.
Buxom Is Better/Gag Boobs: Repeatedly lampshaded (by a milk carton at one point) and poked fun at. Enjoyed by Miya thoroughly.
The Cutie: She's described as "fluffy-looking" by other characters.
Does Not Like Men: More accurately, is intimidated and afraid of men... until Junichi comes along.
Shout Out: The penguin suit, which is probably also a Mythology Gag to those who are familiar with the original game, as the penguin suit also has a baby penguin attached and one of the possible endings with Sae in the game is her getting pregnant.
A second year and Class Representative of Junichi's class, as well as the committee head of the Founder's Festival Committee for the current year. She is hard-working, takes on jobs no one wants to do, and is generally an outstanding student. She is very popular due to this, and teachers find themselves relying on her more often than not... except this turns out to be but a facade for a meaner side.
A-Cup Angst: Episode 13 of Plus reveals her getting into specialized herbal bath in an attempt to increase her chest size.
Adaptation Induced Plot Hole: The anime fails to elaborate on the contents of her diary and the reason she dislikes her sister Yukari.
Becoming the Mask: At the end of Episode 23, and it is not a good thing. Reversed in the next episode with Junichi confessing he still likes her all the same. Cue him getting a 3-hit combo.
Cry Cute: Even after venting out all her frustrations on Junichi for his foolish words and nearly turning her into the nice girl she actually wasn't, the guy actually welcomes it as a sign that the girl he loves is still there, sending her crying in his arms.
Freudian Excuse: Tied in with her dislike for her bubbly older sister Yukari. While Tsukasa prides herself on being efficient, outstanding and successful despite her true attitude, people still prefer Yukari's easygoing nature despite her many shortcomings. As a result, Tsukasa has always felt some resentment against Yukari, especially when people praise her.
Junichi's younger sister. She affectionately calls him "Nii-nii" but is often chastised by him for this; thus, she calls him "onii-chan" outside the house. She tends to be jealous of girls Junichi spends time with, save their mutual childhood friend Rihoko. Her favorite food is nikuman (pork buns).
A Day in the Limelight: Episode 26 is focused on her, and unlike the other arcs and even Risa's episode, there's no romantic development involved. At most, she gets a sudden love confession from a guy in a neighboring class, but she rejects him on the grounds that she's unsure how to handle it.
Animal Motif: Cats. Even her first name is a derivation of the japanese onomatopoeia for a cat's cry, "nya".
Hate at First Sight: Haruka instantly gets on Miya's bad side, likely because Haruka considers her the cutest thing ever and is very prone to glomping.
My Nii-nii Is Off Limits: Most notable with Haruka, whom Miya immediately dislikes. Averted in the case of Rihoko and Miya's two friends, Sae and Ai.
Her hostility towards Haruka is averted in the spinoff manga Amagami: Dreamy Forever where she becomes a Shipper on Deck towards Junichi and Haruka and becomes close to Haruka.
Shipper on Deck: Supports Junichi if he falls in love with any of the girls.
Masayoshi Umehara
Voiced by: Takuma Terashima
Junichi and Kaoru's best friend.
BackStory/Old Shame: Near the end of Tsukasa's arc, Junichi catches him about to burn a letter and tries to stop him. The latter reveals that it was a confession letter from a girl back in middle school, which he never replied to because back then he thought love and romance were "not cool", making it his biggest regret in life.
A friend of Kaoru, who (with Junichi) gave her love advice.
Love Letter Lunacy: An unfortunate example. Keiko has a crush on a boy in her class but is too shy to tell him so Junichi tells her to write him a letter. However, the guy was an insensitive jerk and shows off the letter to his friends much to Keiko's embarrassment. Thankfully, both Kaoru and Tsukasa calls out on what he did.
The Atoner: At the end of episode 25, Risa decides to apologize to Haruka, Kaoru, Sae, Ai, Rihoko and Tsukasa for sabotaging their attempts to hook up with Junichi. May or may not overlap with Easily Forgiven.
Forgotten Childhood Friend: Of Miya, who taught her to call Junichi "Nii-nii". They meet in episode 26, where she even asks Miya to call her "Nee-nee", in anticipation of winning Junichi's heart and eventually having Miya as a sister-in-law.
Morton's Fork: Essentially what Risa was faced with two years ago and her motive for her actions then. Makihara, the girl who stood Junichi up, was planning to humiliate him at their meeting place in front of her friends — Risa included — by rejecting him as a prank. Risa was horrified at the possibility of Junichi being Spurned Into Suicide, so the day before she lied to Makihara that Junichi wanted to meet elsewhere, and Makihara waited there instead, resulting of course in Juinichi being stood up. Either way, Junichi ends up heartbroken.
Secret Character: Arguably the first in this genre and probably the last bastion of the trope for modern video games at large. Her name is always kept hidden, even in the Japanese Amagami Wiki, with forum discussions as the only exception.
Secret Relationship: Episode 25. She doesn't want anyone to know of her relationship with Junichi due to certain actions she's done as a mild case of Yandere.
Her Image Song, secret room, is a nod to their meeting place (an unused preparation room).
Where It All Began: Risa caused the famous rejection from two years ago by misleading the girl into arriving two hours earlier.
In her anime arc, she lies to the girl, named Makihara, that Junichi changed the appointed meeting place, and Makihara waits there instead.
Yandere: If you reject her, she exposes Junichi's Porn Stash to the school (unluckily, he's got some goods to trade with Umehara), ensuring Junichi never gets a girlfriend for the rest of his life in Kibitou. Even his friendship with Kaoru and Umehara is strained, with the two of them keeping their distance from him for their reputation. Miya likewise does not interact with him in school anymore.
Fortunately subverted — big time — in the anime. She became remorseful, and even decided to let go of Junichi because she thinks he hates her. Fortunately the nice guy would have none of it and forgave her.
Mika Makihara
Voiced by: Hitomi Harada
The girl who stood Junichi up two years ago. She appears in Episode 25 of the anime.
Haruka Morishima's 1-year-older cousin from Britain who comes over for a visit. Like Haruka, she's part British, in fact she appears to be a blonde version of Haruka. Appears in the Amagami SS+ series.
Shipper on Deck: Very much supportive of Junichi x Haruka. In fact she actually tries to push them together by warning each of them not to be holding back lest they lose each other.
Talking To Herself: Shares the same voice actress as Haruka, reinforcing the impression of her being merely a blonde Haruka.
