A 19-year-old boy who's just entering college for the first time after having to spend a year in rehab due to a near-fatal fall off a bridge the day after his graduation, which gave him severe retrograde amnesia.
Amnesiac Dissonance: Before his amnesia, he was an angsty wimp. Post-amnesia, he has become a natural leader, defined by a strong will and extreme cleverness.
Amnesiac Hero: He fell off a bridge and suffered a severe head wound that gave him almost total amnesia and loss of personality. His originally personality is actually still intact, but completely separated from the new one.
Blank Slate: Banri seems to have been one after the accident that gave him amnesia, but by the time of the series, he has developed a cheerful, mischievously crafty personality (that hides his angst and obsession with his past). Ironically, it's completely different from his pre-amnesia disposition.
Berserk Button: His past or lost memories can be a big sour point with him. As is people leading him on such as Linda in regards to his feelings and past, or Kouko when she wants them to be Just Friends after his confession and still doesn't seem to have gotten over Mitsuo.
Crossdressing: Dresses as a maid in episodes 11-12.
Driven to Suicide: Nearly jumps off a bridge at the end of Episode 6. Fortunately, Kouko stops him.
Guile Hero: Banri is incredibly quick thinking and frequently saves his friends from trouble or emotional turmoil with just a few words or a single well-placed action.
Examples include saving Mitsuo from embarrassment by turning Kokou's assault-by-bouquet into a rose giveaway, saving his friends from a cult by pretending to want to be a cult member and getting his friends sent off for distracting him, or distracting Kokou and Mitsuo from their Heroic BSOD by tossing them into "hell".
Like You Were Dying: When his memories and past personality begin returning with more frequency, Banri begins to believe that his present self will simply fade away and tries to make his supposed last days as comfortable happy as possible both for himself and his friends.
Mr. Fanservice: Episode 15. Highlights include him wearing a small and tight speedo in the rain , a swimsuit on the beach and just being shirtless in the car.
Nice Guy: Though he has a callous and slightly self-centered side that he keeps in check.
Normally, I Would Be Dead Now: It's a miracle Banri survived the hard fall, since, as shown in a flashback in Episode 4, he fell headfirst from a pretty massive height and had lost a lot of blood.
Smarter Than You Look: His gentle personality doesn't stop Banri from being one of the smartest people in his group of friends.
Split Personality: It's shown early on that somewhere in the back of his head, the Banri from before the accident is still alive and aware of his new personality's life. In the anime's 8th episode, the old personality starts trying to take over because the current personality is in a relationship with Kouko while the old one holds a torch for Linda.
Split Personality Takeover: And succeeds at the end of episode 9, just when the old Banri had accepted that he and Linda would never be together.
Enemy Within: Later in the story, when the Split Personality Takeover doesn't pan out, the older personality resolves to ruin Banri's life by influencing his decisions, or at least ruining his plans, such as making it rain and heavy traffic on the day they went to the beach. Old Banri seems to have given up around episode 18/19, a few episodes after his "curse" nearly caused several of them to die.
Thousand-Yard Stare: He does this in episode 20, after his memories return once again while in the middle of dance during a festival. The last thing he suddenly remembers was waiting for Linda on the bridge, so when he suddenly finds himself in the middle of the festival, he understandably freaks out and runs off.
And again in episode 21, after Koko breaks up with him. It's implied he's left standing there for hours from the shock.
Trauma Conga Line: Episode 20 kicks off one in the form of the consequences of Banri's memories returning and his secrecy about the whole situation starting to pile up, with a whole slew of other hardships to boot. He briefly lapses into suicidal territory, but Nana is there to talk him through the despair.
Your Days Are Numbered: Present Banri Comes to believe this as his memories and old personality begin to return with more frequency.
Break the Cutie/Break the Haughty: On one hand, Kouko deserved a verbal beatdown from Mitsuo for her borderline stalking and harassing Chinami just because Mitsuo was so nice to her; on the other hand she got hosed down so badly she is reduced to a tearful mess.
Happens again, only without the haughtiness when fall asleep at the wheel and gets into an accident. It got worse when Chinami got injured in the process.
Clingy Jealous Girl: She absolutely hates seeing other girls around Mitsuo, such as Chinami in episode 4. Later she gets upset at Banri after she sees him with Linda at a club while posing in a very erotic position for patrons there.
First Girl Wins: She is the first girl seen in the anime. If that wasn't enough of a clue, her interactions with Banri in the opening sequence makes it pretty obvious who she's going to end up with. Naturally things don't go smoothly for them but eventually they manage to patch things up.
Food Slap: When she catches Banri and Linda in an erotic position at the club, she promptly grabs a patrons drink and splashes it in Banri's face. Then she gives him an Armor-Piercing Slap.
Heel Realization: Even she realizes bullying Chinami may have been not the best idea. Played for Laughs in the anime, as she goes Blue with Shock, sweating all over. Then Played for Drama after Mitsuo dumps her, when she tearfully realizes how self-centered she is, having refused to even try to understand what turned him off up to that point.
I Can't Dance: One of her few flaws, besides her... social misunderstandings.
Jerk Ass: Has her moments, especially towards Chinami and Mitsuo.
Jerk with a Heart of Gold: After his explicit rejection, she at least seems to care about Mitsuo despite the unpleasantness between them, and even tolerates Chinami's company when she thinks that'll stop him from becoming totally depressed.
Kick the Dog: Bullying Chinami out of jealousy over Mitsuo apparently getting too close to her. This is what finally prompts Mitsuo to tell her how he truly feels about her.
Large Ham: She's extremely flamboyant and expressive, especially when it comes to love. Best seen when she and Banri become an Official Couple, and where she opens her cardigan to 2D-kun, revealing a T-shirt with a large heart shape, along with an "I Love you" in English to Banri.
Lethal Chef: Implied to be one in episode 13, when she attempts to cook for Banri. She goes to great lengths to avoid him watching her cook, then it turns out her maid cooked the food she had, because the maid saw what a horrible time Kouko was having while doing it. And Banri sees it all anyway because the sleep mask she put on him slips down.
Little Black Dress: Wears a distinctly Audrey Hepburn inspired dress in episode 14, as well as her dress in episode 19.
Lonely Rich Kid: Banri thinks that she is actually this, if her clingy attitude towards Mitsuo was any indication.
Ms. Fanservice: The series is pretty conservative with the ladies, but Kouko's stylish fashion sense and good looks make her stand out as a rather glamorous figure.
Especially evident in episodes 14 and 15.
Not so Above It All: In episode 18, Kouko secretly goes through Banri's mail, and then enters his apartment. She starts acting a bit weird, and then notices Nana watching her from outside the door and freaks out.
Series Mascot/P.O.V. Boy, Poster Girl: She's the most prominent character in promotional material and art (probably because she has the most reason to wear something eye-catching), though Banri is the protagonist and Linda is arguably as important to the plot.
She's Got Legs: Some of Kouko's outfits and art for the anime work well to emphasize this.
Sliding Scale of Beauty: Distinctly a level II World Class Beauty, but her looks are also sometimes described as being on the same level as a level I Divine Beauty.
Spoiled Brat: Shades of this. Kouko is far from the mature woman her looks portray her as which is potentially a result of her rich upbringing. Justified and referenced after she falls asleep on the wheel and causes an accident. Her father dealing with the aftermath and the costs of it causes her to realize just how immature she is, and how she's still not really an adult. Banri tries to reassure her about this by citing the fact that she's still barely out of high school.
Stalker with a Crush: Towards Mitsuo. Later on, somewhat towards Banri, but she tries to tone it down after learning her lesson with Mitsuo.
Thousand-Yard Stare: Two heartbreaking Instances in episode 12, both when she sees Banri and Linda together in a very erotic position at the club, and later when Banri reveals that he has moments where his memories come back and he feels as though he's in love with Linda.
Took a Level in Jerkass: Her breakup with Banri in episodes 21 and 22. The way she delivers the lines to Banri and the others makes her seem like a selfish person, to the point even Mitsuo does a What the Hell, Hero? to her. She does come to regret acting this way however.
Tsundere: No, she doesn't want to be friends with Miss Ultrasound
Unfortunate Name: At least in Spanish-speaking countries, and it could be a reason for a Dub Name Change if the show is licensed in those countries.note Kouko Kaga sounds like "Coco Caga" who is translated as (The) coconut is shitting . This is even worse if you use her name in the Japanese order, since it could sound like "Caga Coco" (Coconut-shitter).
Unlimited Wardrobe: You'll find Kouko in at least one new, fashionable, and attractive outfit every episode.
Vitriolic Best Friends: She gradually starts to warm up to Chinami, largely after both of them spot Mitsuo going into a restaurant with Linda in episode 14, a sight neither one of them seemed happy to see.
Wrestler in All of Us: In episode 18, she tackles Nana after rejecting the latter's job offer, and then puts her in a sleeper hold while begging her not to tell Banri about the crazy things she did in his apartment while he was away. Nana, not being able to breathe, agrees quickly to it.
Wrong Genre Savvy: She once thought Mitsuo was a hardcore Type-A Tsundere who would eventually come around if she stalked him long enough.
Big Damn Heroes: Helps out the Festival Club in episode 23, so that they can have uniforms for their performance during the festival. He also helps reassure Banri that he'll always be there for him, even if Banri loses his memories.
Brutal Honesty: Tells Kouko in no certain terms how he doesn't want to see her anymore.
Chick Magnet: He is hit on first by Kouko, and later a random college student shortly after Chinami turns him down. Then when he goes to film the club Banri, Kouko, and Linda are in for a documentary, two of the female students ask him if he's dating anyone. After Kouko suggests they go out for some tea to distract him from Banri and Linda, the two girls clutch his arm and insist on going with him too.
Innocently Insensitive: In Episode 5, he admits to Banri that he ran his mouth off against Kouko without realizing how much he hurt her. He's aware of it, and it also hurts him.
Locked Out of the Loop: Not done on purpose, but he seemed unaware of Banri's amnesia until around episode 17, when he notices Linda's ticket to go back home, and remembers Banri telling him he was from the same city. He starts asking various characters about it, but none of them seem to give him a straight or complete answer about it.
Mr. Fanservice: Episodes 11 and 12, especially the latter one, where he works at a club party wearing nothing but a thong. Later he's put on stage and poses for the patrons. And then we have episode 15 on the beach...
No Guy Wants to Be Chased: Part of the reason he tries to escape Kouko. The other part is that being chased would have led to being controlled and manipulated into what is essentially a trophy-husband.
Oh Crap: His reaction on Episode 1 when he realizes not only has Kouko tailed him in Fukurai, but also managed to land in the same class as him and Banri, and again in Episode 5, when Linda tells him how much of a Sadist Teacher his civil law advisor is.
Tsundere: Assumed by Kouko to be Type-A regarding herself. In reality, he's more of a Platonic Type-B — generally nice to everyone, but tends to be mean towards Kouko (though with good reason). Nevertheless, he does show some concern for her well-being as her childhood friend.
A second-year student and member of the Japanese Festival Club. She is also Banri's old friend from their high-school days, though he doesn't realize this at first due to his amnesia.
Cannot Spit It Out: Her biggest flaw. She was never able to answer Banri's feelings towards her during high school and when she meets him again after his amnesia, she keeps quiet about their original relationship. Even when it seems like she could have genuine romantic feelings for him, she completely denies them when Banri directly asks her.
Guilt Complex: She feels like she is responsible for Banri's amnesia.
Hopeless Suitor/Unlucky Childhood Friend: She knows she's going well into this territory, due to Banri's amnesia and budding romance with Kouko. Though it turns out that back in their high school days it was the other way around — Banri was hopelessly in love with her, while Linda was ambivalent, which she believes indirectly led to the accident that gave him amnesia. Seeing him in love again seems have brought up insecurities related to that, rather than jealousy or romantic feelings. Episode 12 throws her thoroughly into the latter trope, as Banri wants to sever all romantic notions with her, largely to not upset Kouko. While she seems to agree to it, the look on her face suggests she's heartbroken by his response.
Ms. Fanservice: In episodes 11-12, both she and Nana wear very attractive devil outfits at the same club Banri comes to work at.
Name's the Same: Her first name is Nana, and her punk-rocker friend who lives next to Banri also goes by that name.
Odd Friendship: She's friends with the punk rocker Nana. She tells Banri that Nana used to be in the festival club when she first joined, but eventually quit due to work and her band. But they still hang out together.
Secret Keeper: As the only person who knows Banri's pre-amnesia history. In a Flash Back, she also knows about her brother's fiance's romantic indiscretion, and ultimately seems to not tell him about it in exchange for her staying faithful to him.
Subverted to a certain degree, as she and Banri are actually the same age and would have been in the same grade if not for his accident. She's still his sempai in the festival club though, and he eventually starts calling her just "Linda."
Cannot Spit It Out: It's strongly hinted that she likes Mitsuo, but can't bring herself to tell him. Even when he gives her a Love Confession, she turns him down. To be fair, he asks on a dare from Kouko, and says it in a restaurant, which may have caused Chinami to be a little hesitant at being put on the spot like that. This comes back to haunt her after he starts to show interest in Linda.
Green-Eyed Epiphany: In episode 20, for Mitsuo. Though she knew this before but didn't tell anyone until she confessed to Banri about it in episode 21.
Important Haircut: She shortens her hair in episode 19. She laments that all the guys think she should've kept it long however. She tells Banri she regrets cutting it in episode 21, since it changed her looks considerably, and isn't entirely sure why she did it in the first place, since she kept her hair long for years.
In-Series Nickname: Miss Ultrasonic, in reference to her voice, and used exclusively by Kouko.
I Want My Beloved to Be Happy: She gets mad at Banri in episode 19 when she sees him getting a little too friendly with Linda. She tells him to stop it, because that's the girl Mitsuo likes now, and she doesn't want him interfering.
In episode 21 she reveals that she was actually secretly happy when she saw Linda and Banri talking. She admits to Banri that she hoped the two would date, so that Mitsuo would be free again, and she'd snatch him up this time.
Nice Girl: Even when Kouko was hostile to her she was still rather nice to the former.
Not so Above It All: She's generally somewhat mature, but once in a while will do silly things with the others, such as making goofy faces in front of her camera.
Token Mini-Moe: She really doesn't look her age, and so do several of the characters she voices.
Took a Level in Jerkass: She becomes openly hostile towards Banri from episode 19 till 21 after seeing him getting a little too friendly with Linda. She reveals to him that she was really upset at herself for missing her opportunity to get with Mitsuo, and was secretly happy when she saw them together. But she tells him that instead of getting mad at herself, she took it out on him instead, and admits to Banri that she still loves Mitsuo.
Vitriolic Best Friends: With Kouko, who gradually warms up to her after they spot Mitsuo going into a restaurant with Linda, a sight neither of them seemed happy to see.
