A delinquent and leader of his three-man clique, who made the mistake of trying to bully the Game Development Club (temp) one day, only to end up being bullied into joining. Now an unwilling member of the Game Development Club (temp), he is forced to spend his days bitterly dealing with their nonsensical antics.
Badass: Although he doesn’t get many chances to show it.
Jerk with a Heart of Gold: Leaning on a pretty Nice Guy with a fairly convincing Jerkass Façade. He's brash, cocky, and can be a bully because he can; that said, he's actually a good friend, classmate, clubmate and brother, as shown when he agreed to join the Game Development Club (temp) to help Roka fulfill her dreams, defended Takao before a PTA meet after the "zipper-launcher" incident, and treats the otherwise beleaguered Funabori with kindness (which in turn earns her affection).
Large Ham: It comes with being voiced by the same guy who gave the world Kamina. It’s not how he usually acts, but the sheer absurdity around him on a daily basis results in him always yelling at everything! Almost all the time!!! This becomes more prevalent as the series goes on.
The short, quirky founder and captain of the Game Development Club (temp). She used to be a member of the real Game Development Club, but she didn't get along with the rest of its members, so she started her own.
Dishing Out Dirt: Earth is her "elemental" motif, evidenced by her habit of throwing punches (which she also claims to be earth-"elemental") and hurling dirt on people, as well as her fondness for sand castles.
Knight Templar Big Sister: To Roka in a surrogate way — harm her (physically or emotionally), and she will do anything in her power to lay down the pain on you.
Pet the Dog: Roka is (mostly) the only person who she ever shows any semblance of kindness, though there are a few exceptions. At the end of the School Festival she comforts a crying Takao after losing their bet, telling that she doesn't care for winning, so long as Roka keeps her club. In a rare moment of honesty she even apologizes for her angry outburst that nearly destroyed Takao's club several months ago when she learned what they were doing to Roka, admitting that she let her wrath get the better of her back then.
Put on a Bus: Takao tags along with the Game Development Club (temp)’s Cast Herd for the most part, so the other members stopped being relevant after the first few chapters, although Inada will show up occasionally.
A very brief and offhand reference was made to Sakuragaoka in chapter 44.
President of the real Game Development Club and an old friend of Roka. While appearing elegant and dignified among her schoolmates, the rest of Roka's club see her as nothing more but a big-breasted crybaby who is nevertheless an important friend still.
Cry Cute: Played for Laughs after Chitose forced her to admit defeat on their bet to see which of their booths during the School Festival would attract the most visitors, and again when Kenji unwittingly reminded her of her loss.
Wardrobe Malfunction: During the Tournament Arc, she tried to zip her tracksuit to avoid embarrassment. Because her chest is too big for the jacket, the zipper ultimately snapped, sending the pull tab flying toward Kenji and accidentally knocking him out. That incident actually caused a mini-scandal, as concerned parents thought the PE suits are dangerous (when really, it's just Takao's breasts' fault).
Student Council Vice-President and one of Kazama’s friends. While in public he expresses dismay at the kind of lifestyle Kenji leads, in private is more or less an honorary member of the latter's gang, and aspires of usurping Chitose’s presidency.
Butt Monkey: And surprisingly so. Because she's such a perfect wife, she gets caught up in the Game Development Club's antics, screwed with by everyone who isn't Kenji, and even gets yelled at for trying to be nice. In addition, every time she shows favor towards Kenji, every other guy in the class surrounds her and causes a ruckus, to the point where she's even forced to bandage everyone's shoulders when they aren't even hurt.
Parody Sue: She's sweet, considerate, and skilled at household chores. Whatever angle you look at her, she makes for the perfect housewife. And all she gets for her trouble is being constantly inconvenienced by her admirers and being forced to bear with the general insanity of her schoolmates.
Big Brother Worship: A reasonable example. While at school they don't interact much with each other, in private she is pretty close with Kenji and makes his lunches. She is annoyed when Sakura acts like Kazama is her brother as well. And when really hurt, she does call him "onii-chan".
Roka's younger sister, a first-year at Higashifuge Academy, and herself a member of its own game development club.
Annoying Younger Sibling: How Roka treats her. Even Kenji agrees that Tsutsuji doesn't make for good little sister material.
Big Sister Worship: Adores Roka a lot. She doesn't repay the fangirling. Even Kenji correctly guesses that she's the kind of person who'd prepare Roka a bento with the words "I Love Onee-chan" on it.
Book Dumb: Kusshi-senpai implies that she keeps failing to get into Fujou and join Roka because both of her procrastination and frequently being distracted by Roka's activities.
Cry Cute: Played for Laughs whenever she thinks her sister's club activities are beginning to take a toll on their sisterly relationship, and again while whining that she doesn't want Kenji for a substitute older sibling (and that is after she herself did so as a retort to Roka "disowning" her and putting Noe in her place).
My Sister Is Off Limits: Dislikes anyone she thinks is consuming Roka's time, particularly Kenji, who Roka keeps talking about all the time, even at home.
