Ever since her older brother died, Teru Kurebayashi has been watched over by the mysterious Daisy, whom her brother said would look after her in his absence. Though they communicate only through e-mail on her phone, his gentle, encouraging words have been a great source of comfort to her. Her life becomes slightly more complicated when, after accidentally breaking a window at her upscale school, she is made into a slave by the school janitor Tasuku Kurosaki, a rude, sadistic, minorly perverted Comedic Lolicon who has no qualms about lounging around while she does all the work. He's totally unlike her beloved Daisy; but little does she know that the two are, in fact, the same person.
A shoujo manga by Kyousuke Toriumi (an alias, the author is a female) that was published from May 2007 to October 2013, with a total of 16 volumes released. The series is also licensed by Viz and 14 volumes are out in America.
Examples:
- Almighty Janitor: Kurosaki is a former software engineer and an accomplished hacker/cracker who is not above making death threats to those who intend to hurt Teru.
- Almost Kiss: In chapter 20, Kurosaki tries to kiss Teru. They're interrupted by Riko.
- Alpha Bitch: Initially, the student council president Rena.
- Arson, Murder, and Jaywalking: Onizuka commiserating with Teru about Kurosaki: "He's lazy, unscrupulous, and perverted. Plus he can't tell jokes at all."
- The Atoner: Kurosaki, in creating Jack O' Frost and feeling guilt over his father being a spy, nearly commits suicide into thinking that would redeem his "sins." Souichirou stops him. He later feels that he cannot be forgiven for Souichirou's death, feeling responsible for it as Souichirou dedicated the remaining time of his life protecting Kurosaki until it wore him out.
- Berserk Button: Do. Not. Mess. With. Teru. Kurosaki will get angry, and you won't like it.
- Bland-Name Product: Teru and Kurosaki buy candy at a 7-10.
- Cool Big Sis: Riko towards Teru and Kurosaki. She could have become Teru's literal Cool Big Sis because she was engaged to Teru's older brother, who untimely passed away prior to the story's beginning.
- Clear Their Name: Kurosaki's reason for becoming a hacker was to prove to himself (and everyone else) that his father was not really a traitor.
- Comedic Lolicon: Kurosaki is jokingly referred to several times as such by several of his acquaintances. However, he can only really be defined as one under the least pedantic definition of the term.
- Cuteness Proximity: Kurosaki has a hilarious one when he unconsciously brings a dog home during the rain in Chapter 28.
- Death by Origin Story: Played straight—Teru's older brother's death and before-death deal with "DAISY."
- Defeat by Modesty: Kurosaki rips off the shirt of Chiharu Mori to prevent her from following him after he steals her laptop to save Teru. Mori's left stranded in the washroom, completely topless.
- Driven to Suicide: Kurosaki tried to commit suicide in the past. Luckily, Souichirou stopped him.
- Dude, She's Like in a Coma
- Eating the Eye Candy: Teru steals glances at Kurosaki when he is walking around shirtless after a shower. Of course, when he tells her that if she wants to look then just look she denies it.
- Everyone Calls Him Master: Masuda, the manager at the restaurant Kurosaki normally attends and one of Kurosaki's confidants.
- Ferris Wheel Date Moment: Kurosaki and Teru attempt to have one in Chapter 33 but that goes horribly wrong. Then in Chapter 68 they finally have a real date on the Ferris Wheel and Kurosaki confesses his love for Teru
- Flower Motifs: Well, it is called Dengeki Daisy. The author often puts blue daisies in the story.
- Forceful Kiss: Akira steals Teru's first kiss in Chapter 32.
- Headbutt Thermometer: Kurosaki loves to fluster Teru this way.
- I Thought Everyone Could Do That: Teru asks a (drunk) Kurosaki to solve a code that Kiyoshi gave her. After he solves it in five seconds, his response clearly indicates that he wasn't aware that this was (at least somewhat) extraordinary.
- Innocent Innuendo: Teru tells Riko about her night together with Kurosaki and she hilariously misunderstands.
- Indirect Kiss: The last page of chapter 3 with a soda can, but it is not like anyone made a big deal out of it.
- Interrupted Suicide: Kurosaki attempted suicide in the past but was stopped in Soichirou. In Chapter 35, Rena mistakenly thinks Teru is trying to commit suicide (following Kurosaki's disappearance) after the former spots the latter on the school's rooftop and "stops" her.
- Leaning on the Fourth Wall: The manga often lampshades things this way. A memorable exchange from chapter 37:Teru: Suddenly, there was a code related to foreign countries...it was like reading a bad manga!
Kiyoshi: At least this isn't a shojo manga. - Like Brother and Sister: Teru's initial view of her relationship with Daisy.
- Looking for Love in All the Wrong Places: Rena.
- Loves My Alter Ego: Inverted; To Teru, Kurosaki is both the school janitor and Daisy, the mysterious person who has looked after her ever since her brother died. Teru is in love with Kurosaki and Kurosaki is in love with her, but he doesn't want her to know that because he feels that he shouldn't love her while keeping that fact that he's Daisy a secret.
- Playing with a Trope: Kyousuke Motomi loves to do this, as seen in Dengeki Daisy, Beast Master, and her other works. Lots of Shoujo tropes are turned on their heads here; for example, a Flower Motif is expected for a series called "daisy," though just as often as it's played straight, you can turn the page and discover the cascade of flowers was actually debris from Teru trimming the trees in the garden. Also, the more romantic a moment is becoming, the more likely you will turn the page and see them ripping out each others' hair, pinching the other's nose, etc. Belligerent Sexual Tension at its finest.
- Pretty Boy: According to Riko, Kurosaki was a Bishounen in the past.
- The Professor: Professor Midorikawa, responsible for 'M's Testament' Not part of the current team, but plays the professor role in several character's backstories.
- Redemption Demotion: Takeda undergoes a n oddly played-with version of this trope. While he retains his competence in serious scenes, and even gets more competent, outside of those few situations, he's pretty much become the casts' Butt-Monkey.
- Replacement Goldfish: Teru gets really interested in a hooded boy she meets three times because of his resemblance to her late older brother Souichirou. Turns out he's not such a good guy like she thought when he steals a kiss from her.
- Sacred First Kiss:
- Teru's "first kiss" was stolen by Akira.
- An interesting subversion in that Teru was given CPR by Kurosaki much earlier. Whether or not that counts as a kiss is debatable.
- Shipper on Deck: Teru's brother shipped her with Kurosaki, which is saying something considering this is Souichirou. In a flashback in Chapter 38, Riko suggests for Kurosaki to ask out Souichirou's little sister, who Kurosaki has never met yet, but Kurosaki is against it, as he claims he's not a Comedic Lolicon and that the girl is probably an A-cup.
- Teacher/Student Romance: Arai-sensei and Rena. In spite of what happened, they still care about each other.
- Tsundere: Kurosaki, even more so than Teru herself. Also, Rena. Souichirou showed signs of it as well in the past, acting strict towards Kurosaki, only to confess his worries over him later to Riko, and that his tsun-tsun treatment of Kurosaki was a calculated move for the younger man's own good. Fortunately, Teru is aware of Kurosaki's Tsundere tendencies, and she seems to deeply enjoy using it against him. Most prominently in chapter 41.
- Would Hit a Girl:
- Kurosaki constantly threatens anyone who hurts Teru, girl or boy. He also makes true to his word by choking Mori and stealing her clothes after she stopped the Ferris wheel Teru and Akira were on.
- Kiyoshi hits Teru to snap her out of her depression over Kurosaki's disappearance.
