The inhabitants of "Nunnery" who are Otaku in some way or another. Their apartment is owned by Chieko's mother, who has gone abroad to follow her fangirl crush. Although Chieko is the manager, Mejiro-sensei the resident Mangaka enforces a strict "No Men" rule and employs the other inhabitants as assistants.Tropes applying to all of the "Nuns" are:
Ditzy Genius: She's a walking jellyfish encyclopedia; not so much with other stuff.
Let's Get Dangerous: She manages to push her social phobias aside long enough to demand that a single jellyfish be moved to a safer tank. Don't get in her way when she's making a jellyfish dress, either.
Meaningful Name: The kanji for Tsukimi (月海) reversed can be read as "kurage" (海月), or "jellyfish".
A college student who enjoys cross-dressing. He fears being pushed into politics by his family, as he considers his true calling to be the fashion world.
Agent Peacock: Kuranosuke is a slightly more realistic than usual version. He saves the jellyfish for Tsukimi and other awesome stuff.
Determinator: He's not one to give up, even when everyone else is.
Dude Looks Like a Lady: Enough that, when the Nunz discover his breasts are fake, they instead jump to the conclusion that he's a very flat-chested girl wearing inserts out of insecurity.
Fake Boobs: When Kuranosuke passes out in the lobby of their apartment building, Mayaya attempts to help by applying Vicks Vapo-Rub to "her" chest, and in the process discovers that Kuranosuke's breasts are fake. Mayaya and the other members of the Sisterhood present completely miss the obvious and instead accuse Kuranosuke of padding "her" bra to hide her A-Cup Angst.
Gender Vocabulary Slip: Slips into the ore pronoun, but since he's so good at cross-dressing, he still passes as a bokukko (with a bit of help from Tsukimi).
Hidden Depths: One of the reasons Kuranosuke cross-dresses, revealed late in the series, is a desire to connect with his absent mother, who often gave him pretty things and showed off her dresses to him; not to mention a half-subconscious belief that, if he had been born a girl instead of a potential heir, his mother might not have left/been separated from him. The series leaves the exact nature of her departure unexplained.
Stupid Sexy Flanders: A lot of male fans state-side have really taken a shine to Kuranosuke's "Kurako" persona as of late. Not to mention the fact that both the Koibuchi family's house staff and Prime Minister/Uncle Negeishi's aides have noted that he is quite the looker, and very attractive. Even Inari's assistant/co-worker agrees, much to her vehement chagrin.
Adorkable: Especially when he's crushing on Tsukimi. He's a successful businessman and respected member of the society, but he has no idea of how to function in dating and relationship world.
Loves My Alter Ego: Falls for Tsukimi's "After" mode. Doesn't recognize her and ignores her in "Before" mode. In the manga he eventually figures out they're the same person, and decides he still likes her anyway.
A Man Is Not a Virgin: Averted. He's the closest thing this cast has to a responsible, stable, well-functioning in the society adult man and he's revealed to be a virgin at the age of 30.
Primal Scene: G-rated version. His phobia of women comes from catching his father cheating with Kuranosuke's mother at a young age.
Secret Keeper: Kuranosuke's mom calls Shū to ask him to get Tsukimi's original jellyfish dress after seeing her son on TV. Naturally, Shū can't tell Kuranosuke.
Would Hit a Girl: Shu proved that if you push him too far, he will retaliate. Though, admittedly, the victim completely deserved it. He later apologizes, which throws Inari and ruins her blackmail scheme speech.
Shū and Kuranosuke's father, whose delivery is nearly always deadpan.
Heir Club for Men: The reason why he took Kuranosuke from his mom is because he was born a boy. In the chapter 63 it's revealed that Lina did plan to raise Kuranosuke on her own but realized that she's too young and that task's too big for her, and thus she gave up her son to his father. Kuranosuke still thinks that the reason was that he's a boy.
Self Induced Allergic Reaction: Breaks out in hives from eating manila clams, which he knew would happen anyway when he attempted to save Shu from Inari's advances.
Too Much Information: When Hanamori is surrounded by the "24 Ophelias" he blurts out that he's so obsessed with cars that his girlfriend left him because he loves cars more than her. Later, he lets it slip that if he's bribed with cars he'll reveal anything to anyone and at the fashion show goes into great detail that Kuranosuke is just a cross-dresser, not transsexual.
Watch the Paint Job: He really pampers those Benzes. Lucky for him, none of them have been wrecked... yet.
He's mentioned that he broke up with his own girlfriend because he preferred to spend more time with his Benzes than her.
An Indian woman who works with her brother in a sewing workshop. She agrees to help Kuranosuke and Tsukimi, though she is constantly telling them they're idiots for going into a industry they know nothing about.
But Not Too Foreign: Nisha is Indian but speaks fluent Japanese since her ex-husband was Japanese.
