Love in the Mask

가면속의 사랑

Takemoto, Novala

Meet Momoko, a "Lolita" decked out to the nines in the finest (and frilliest) of Victorian haute couture. The only scion of a drunken interlude between a cowardly yakuza and an inebriated bar-hostess, Momoko's mom has since split the scene, and, after various ill-fated scams that involve imitation brand name merchandise, Momoko's dad relocates them to the boondocks of rural Ibaraki prefecture. To escape her humdrum existence, Momoko fanaticizes about French rococo, dreams of living in the palace of Versailles, and buys all her extremely lacy clothes from an expensive Tokyo boutique.

Meet Ichiko, a tough-talking motorcycle grrrl (on a tricked-out moped) who leads a ladies-only biker gang known as the Ponytails. Together, this unlikeliest of duos strike out on a quest to find a legendary embroiderer, a journey on which they encounter conniving pachinko parlor managers, legendary street-punks, and anemic costumers. Who knows, they might just make it big...if only Ichiko would stop head butting Momoko in the forehead. Novala Takemoto's break-though novel Kamikaze Girls, already a cult-classic in Japan, is more than a wry coming-of-age picaresque, it's a new way of life.

While most people find the world mundane, five-year-old Yotsuba Koiwai sees it as a treasure trove of amazing bustle and wonderful places to explore. When she and her adoptive father, Yousuke, move to a new city, the energetic young girl naturally sets out to investigate the neighborhood on her own.

After a few incidents at the local park, the Koiwais become acquainted with their neighbors, the Ayase family. Their three daughters—mischievous college student Asagi, responsible high school student Fuuka, and kindhearted grade school student Ena—eventually all take a liking to Yotsuba and join in on her antics, despite their sheer ridicule.

From learning how to use a swing to figuring out how to stop global warming with air conditioners, Yotsuba's ability to infallibly find fun in everything, both amazes and annoys the people around her. Along with Yousuke, the Ayases, and friends she makes along the way, Yotsuba embarks on daily adventures, each one a step in her quest to enjoy the simple things in life.
