Magikano is a manga series by Takeaki Momose, which was later adapted into an anime series directed by Seiji Kishi and written by Hideki Mitsui.The story centers on Ayumi Mamiya, a witch cursed to lose her powers, and Haruo Yoshikawa, an apparently ordinary high school student whose three sisters (Maika, Chiaki, & Fuyuno) are witches who use their magical powers to keep him protected and ignorant about the existence of magic. Now Ayumi must wake up Haruo's latent powers to save herself, but his sisters have other ideas.Their classmates include Hajime Hario and Sora Fujiwara, male members of the "Supernatural Science Club" that seems more interested in selling dubious products; as well as Yuri Kurosu, the student council president. Marin Nijihara (a catholic witch-hunter) and Rika Anju (a meido to the Yoshikawa household) show up later.
This manga provides examples of:
Absurdly Powerful Student Council: While Yuri doesn't take it to the extreme that some other shows do, she does abuse her privileges whenever it concerns Haruo, such as showing up to his house when she hears that Ayumi is living with him, or the other girls terrible roles in the play in episode 9. The other characters often point out that she's abusing her powers.
BFS: Yuri has one during her battle mode. Can double as a hovering surf board.
Big Brother Attraction: Maika, to Haruo. She's always showering him with affection, hiding in his closet and watching him sleep, trying to bathe him, modeling lingerie for him to see (even wearing it on top of her school uniform to give him a little preview), and attempting to drive away any and all other female attention from him.
Big Eater: Chiaki. However, she claims to enjoy exercising even more than she enjoys eating.
Curb-Stomp Battle: The ghost girl, using Haruo's magic, absolutely stomps all of the witches attempts to fight.
Determinator: All of the girls competing in the race in episode 8 seem a bit too focused on trying to win. Then it's hilariously subverted when Chiaki wins because she won 40 eating contests, making the 30 points from the race worthless. The girls are not happy about that.
"Groundhog Day" Loop: It turns out that all the events in the series have happened numerous times before and must be changed cardinally to progress. However there is indication that this time round it will be different.
Temporal Theme Naming: The Yoshikawa family uses the seasonal motif, with Haruo (Spring), Maika (Summer), Chiaki (Autumn) and Fuyuno (Winter).
Thanks for the Mammary: When Ayumi first meets Marin in episode 5, she accidentally launches a spell when Haruo shows up, which causes Marin to get knocked back into Haruo. Ayumi then sees him grabbing her chest, and immediately gets jealous about it.
