    Main Characters 

Kaname Tsukahara

Voiced by: Yuki Ono, Yumi Uchiyama (young)

The straight-laced and apparent Only Sane Man of his group of childhood friends, Kaname is a studious person, being both Class Representative and Student Council President, and is often the joke of his friends.
  • Memento MacGuffin: A photo of Hisako, Hisako's sister Shizuna, and himself. This hints at his feelings for Shizuna.
  • Oblivious to Love: Doesn't notice Hisako too much. At first.

Shun Matsuoka

Voiced by: Toshiyuki Toyonaga, Mari Hino (young)

An effeminate young man and fellow childhood friend to Kaname, Yuki, and Yuta. He is kindhearted and is sometimes mistaken for a girl.
  • Adaptation Dye-Job: An interesting case in that colored pages in the manga show him either with pink hair, like the anime, or light brown hair.

Yuki Asaba

Voiced by: Ryohei Kimura, Akane Ueda (young)

One of the twins. Yuki has poor social skills but has great athleticism. He only does things if he gains something in return.
  • All Love Is Unrequited: He develops some interest akin to a crush on the pretty school cafeteria worker Kayo, but she seems oblivious to his feelings and ends up leaving the school and moving away in order to pursue her career as a hair stylist.
  • Big Brother Worship: He has quite the brother complex when it comes to Yuta.
  • Genius Ditz: Is surprisingly good with sports when he actually puts some effort into it.
  • Idiot Savant: See Genius Ditz.
  • In-Series Nickname: "Yukki".
  • Likes Older Women: Seemed awfully interested in the cafeteria worker Kayo.
  • Momma's Boy: Vastly prefers his mother over his father.
  • Not Good with People: He's not good at conversing with others beyond his group of friends and has to be forced into joining a school club. When he becomes interested in Kayo, he denies the idea of her being "pretty/beautiful" in his head and initially ignores her when he learns she is leaving the school.
  • Otaku: People are always surprised that he's such an anime and manga geek considering he's not your stereotypical weird and unpopular anime-nerd.
  • Single-Minded Twins: Subverted. Yuta is the more responsible one.

Yuta Asaba

Voiced by: Kouki Uchiyama, Yuuko Mori (young)

One of the twins. Yuta is the older twin, apparently the leader of the two and seemingly more mature than the rest of his friends.
  • Like Brother and Sister: To Mary. He's always the one to first notice when she's feeling down.
  • Momma's Boy: Though he gets along with his Dad better than Yuuki, the author has stated that both boys prefer their mother.
  • Nice Guy: If not for his occasional trolling of Kaname, his niceness would probably rival Shun's.
  • Secret Relationship: Was in one with Takahashi in Chapter 9/Episode 7. He continues to have some Ship Tease with her in later chapters, though.
  • Sick Episode: Had one in a flashback in Chapter 4/Episode 3.
  • Single-Minded Twins: Subverted since Yuki is the lazy one.

Chizuru Tachibana

Voiced by: Miyu Irino, Mana Hirata (young)

A New Transfer Student who briefly played with Yuki when they were children. He joins the boys' group.
  • I Want My Beloved to Be Happy: He helps Masaki with her affections for Shun several times in order to make her happy (e.g. retrieving her bear key chain and cheering her up when she gets upset over Shun). Subverted in that that doesn't mean he won't stop pursuing her romantically.

    Supporting Characters 

Masaki Satou

Voiced by: Miyuki Satou

A first year high school student who is initially prideful and dislikes Shun. She soon develops a crush on him.

Koichi Azuma

Voiced by: Kosuke Toriumi

The boys' teacher at Hamare High School. Koichi is cool and is a role model to others. He was an alumni at the school alongside his best friend Akira.
  • Big Brother Instinct: Possibly because he already has a younger brother, the way he treats Akira can be seen as this.


Voiced by: Yuuki Kaji

Koichi's best friend.
  • Childhood Friends: With Koichi.
  • Deliberately Cute Child: He manages to move on to the next grade despite his bad grades because he wouldn't stop crying in front of his teacher.
  • Demoted to Extra: In the anime, anyway. He appears less prominently (though more so than Koichi) due to the first season not showing the flashbacks of his younger years with Koichi (aside from the minor preschool-visiting one) and decreasing his screen time in the episode he properly debuts in.
  • First-Name Basis: Despite being far older, Shun and co address him by his first name. Likewise, Akira also addresses all of the boys by their first name.
  • He Is All Grown Up: Compare and contrast how he looks now compared to his high school self.
  • Heterosexual Life-Partners: With Koichi.
  • Hypocritical Humor: Akira's teasing towards Chizuru's height as the "Chocobanana" guy comes off as this given how much shorter he was in high school.
  • Odd Friendship: With Koichi.
  • Older Than They Look: In high school, he was short and resembled a child. Present day and nearing his thirties, he looks like a teenager.
    • He still looks fairly young as an adult. Chizuru and co initially mistake him for a high schooler.
  • No Indoor Voice: His default mode of speaking.

Hisako Aida

Voiced by: Sayuri Yahagi

Kaname's neighbor and childhood friend.
  • Ship Tease: With Kaname in Chapter 60 and Chapter 61.

Shizuna Aida

Voiced by: Mamiko Noto

Hisako's older sister.

Youko Tsukahara

  • Oedipus Complex: The gang likes to tease that Kaname's relationship with her resembles this.
