Crown

Crown is a Shoujo manga series by Shinji Wada (author) and You Higuri (artist). The English version was licensed by Go!Comi, but only made it to volume 2.

Mahiro, a cute Ordinary High School Student, is orphaned by a tragic accident, and some shady types are after her. Mahiro doesn't know it, but her necklace is the crown jewel of Regalia, and Mahiro may be the rightful heir! Luckily, her long-lost brother Ren, now working as a mercenary, returns to take care of her, along with his partner Jake; they both are, of course, just as hot as they are Badass. An over-the-top exercise in shoujo genre cliches, combined with Shonen-esque action sequences.

This work provides examples of:

 * Badass: Ren and Jake.
 * Beauty Equals Goodness: Lady Fibula, oh so much..
 * Broken Bird: Is 's Backstory, as.
 * Brother Sister Incest: Ren and Mahiro like each other a lot. There's a very, very faint suggestion that they like each other "like that." Let's hope they're Not Blood Siblings.
 * But Not Too Foreign: Ren and Mahiro are half-Japanese (through their mother), half-Regalian (through their father).
 * Cinderella Circumstances: Mahiro with the Iizaka, cousins of her mother, and their kids ; they became their legal guardians so they could get the house and money she inherited from her deceased mother, and then treat her like crap and make her do hard labour. That is, until Ren intervenes, Crowning Moment Of Awesome-style.
 * Defeat Means Friendship: Bad guys come after Mahiro, get their butts kicked by Ren and Jake, and then hang around and help with the housework.
 * Dressed in Layers: Ren and Jake apparently wear camouflage gear and bulletproof vests under everything.
 * Good Scars Evil Scars: Condor has a cross-shaped scar similar to Sousuke Sagara's, except it's located right under his left eye. Doesn't help that Condor looks a lot like Sousuke.
 * Homoerotic Subtext: Strictly for Fan Service, and lampshaded. "Why are we taking a shower together?"
 * Everythings Sparkly With Jewelry: The requires payment in gems, since he wishes to cover himself in things as beautiful as he is.
 * Foreign Fanservice: Ren. Particularly oddly explained: Ren and Mahiro come from an Asian kingdom where everyone is blonde. Suuuure.
 * God Save Us From the Queen: Regalia's current ruler, Lady Phoebula, is eeeeevillll.
 * He Man Woman Hater: Jake, who, much like Guy of Tales of the Abyss, is ill at ease with cute girls, and litterally freezes when embraced by one. Since Mahiro has a tendency to do this without thinking, Hilarity Ensues.
 * Heroic Sacrifice:.
 * Legion of Lost Souls: Ren and Jake are former members of the French Foreign Legion.
 * Memento MacGuffin: Mahiro's necklace, the titular "Crown", which also happens to be a Mineral MacGuffin.
 * Noble Fugitive: Mahiro, although she doesn't know it.
 * Only Known By Their Nickname: Condor, whose real name is Chondrite Bourne. His real name is used from time to time, but he's only mostly referred as Condor.
 * Orphan's Plot Trinket: Mahiro's necklace, the titular "Crown", is the crown jewel of Regalia (although she doesn't know about this), and of course the evil usurper is after it.
 * Patriotic Fervor / Green Eyed Monster: These two tropes in combo are the Backstory behind Lady Fibula's Start of Darkness:.
 * Sprouting Ears: Mahiro, because she's soooo cuuuute.
 * Stuff Blowing Up: Far too much for a shoujo series.
 * Tastes Like Diabetes: Mahiro.
 * Troubled but Cute: The Condor.
 * Unwanted Harem: There's Ren and Jake, then they pick up and ...
 * Villainous Crossdresser: Promptly experiences a Heel Face Turn and gets added to the harem.
