Serufu Yua (結愛 せるふ, Yua Serufu) Voiced by: Konomi Inagaki Portrayed by: Hinano Kamimura A laid-back freshman attending Gatagata Girls' High School who ends up joining the DIY Club. She is very accident-prone, with a perfect attendance record at the nurse's office. Because of her being prone to injury, she is often seen with bandages on her body. Her name in Japanese order is a homonym of the "yourself" in "do it yourself". Miku Suride (須理出 未来, Suride Miku) / Purin (ぷりん) Voiced by: Kana Ichinose Portrayed by: Iori Noguchi Serufu's childhood friend and neighbor who attends Yuyu Girls' Vocational High School for technology as a first-year student. She is nicknamed "Purin" by Serufu (and subsequently "Pudding" by Jobko) due to her cheeks puffing up when she pouts, and is often not honest about her feelings, particularly when it comes to Serufu. Her surname and nickname ("Suride Purin") are a play on “3D print”. Rei Yasaku (矢差暮 礼, Yasaku Rei) / Kurei (くれい) Voiced by: Ayane Sakura Portrayed by: Akiho Moriyama A third-year student at Gatagata and head of the DIY Club. She has a strong passion for DIY, although this has led to some weird rumors about her around the school. Her family runs the Waku Waku Wan Wan hardware store. Takumi Hikage (日蔭 匠, Hikage Takumi) / Takumi (たくみ) Voiced by: Azumi Waki Portrayed by: Kokoro Hirasawa A shy first-year student at Gatagata and Serufu's classmate, who also joins the DIY Club. Kokoro Kōki (幸希 心, Kōki Kokoro) / Shii (しー) Voiced by: Karin Takahashi Portrayed by: Mai Kikuchi Miku's classmate at Yuyu, who is very friendly and energetic. She grew up in Southeast Asia. Because she does not go to Gatagata, she cannot be an official member of the DIY Club and is instead an external member. Juliet Queen Elizabeth VIII (ジュリエット・クイーン・エリザベス8世, Jurietto Kuīn Erizabesu Hassei) / Jobuko (ジョブ子, Jobuko) Voiced by: Nichika Ōmori Portrayed by: Shizuku Ōta A 12-year-old child prodigy from the United States who ended up enrolling at Gatagata instead of Yuyu due to a kanji spelling error and is staying at Miku's house. As she doesn't like her full name, she adopts the nickname "Jobuko" from Serufu after she hears her say "Good job!". She uses her skills and state-of-the-art technology to assist with her DIY projects. She returns to the US at the end of the series, as her stay in Japan was intended to be temporary. Haruko Hoketsu (法華津 治子, Hoketsu Haruko) Voiced by: Yumi Kakazu The school nurse at Gatagata and advisor for the DIY Club, who constantly tends to Serufu's injuries. It is revealed later in the series that she is also an alumna of the DIY Club. Serufu's mother (せるふの母, Serufu no Haha) Voiced by: Kikuko Inoue Serufu's mother, who is just as laid-back as her daughter.
