If you're a fan of no holds barred street fighting with camaraderie elements thrown in, sprinkled with a dash of humour (from sight gags to the toilet variety), then Crows: Episode 0 would be right up your alley. It's fight club in schools where black leather is the new uniform. Oozing plenty of testosterone and machismo, there are still enough tender moments to make you cringe, bearing in mind that after all, these are pretty looking boys with mean and tough looking exteriors, but sometimes still softies at heart.
Zero Two engages the creature in her FranXX, but it is heavily damaged in the skirmish and crashes near Hiro. The art direction is beautifully peppered with plenty of graffiti art, and your eyes would just automatically wander off to read just about every word that's spray painted out there. She introduces herself by her codename Zero Two, which is known to belong to an infamous FranXX pilot known as the 'Partner Killer.' Before Hiro can digest the encounter, the Plantation is rocked by a sudden Klaxosaur attack. Here, it's the good old fisticuffs without a lot of frills, though styled to make the characters seem to have super-strength, no thanks to the sound effects of course. However, this is without the effects laden stylistic fight sequences where the exponents possess superhuman powers and abilities. You can't help it but Korea's Volcano High comes to mind for comparison. As the saying goes, one mountain cannot hide 2 tigers. As his reputation grows, so does his threat towards Serizawa, which sets up the inevitable climatic showdown where the rival gangs gotta settle who's gonna rule the school. For the most parts, the story is simple to follow, as we shadow Genji in his quest to conquer the high school class by class, through sheer brute force, gaining of respect, or simply just friendship established. But of course there are unwritten rules to follow in order to engage the top, and he enlists the help of a two-bit average Yakuza hoodlum Ken Katagiri (Kyosuke Yabe) to help plot his path of success. Unification of all levels in the school is a challenge, and new boy Genji Takaya (Shun Oguri) throws down the gauntlet on the first day to take down reigning school gangster Tamao Serizawa (Takayuki Yamada), which he finds impossible given that the latter's picked up by the police. Crows: Episode 0 is set in an all boys Japanese high school, where instead of having educational classes and courses, what gets put on screen (I haven't read the manga obviously) happens to be an ecosystem of triad society split into different turfs according to grade levels, classes and reputation. Known for movies like Audition and Big Bang Love, Juvenile A, both which were released here, this is probably one of his more accessible films to date, even though it treads on familiar territory with elements of the yakuza.
However, with Crows: Episode 0, gone are the extreme violence, though it still retains some flavour normally found in a typical action flick.
CROWS ZERO 3 DRAMANICE MOVIE
Also, just to explicitly say you are being nonspecific about the lower bound.Directing a movie based on a manga isn't something new for Japanese auteur Takashi Miike, who also adapted the ultra-violent Ichi the Killer for the big screen. I think the notation is designed like this just to parallel the "many" notation. use "zero or one" if it can be 0 or 1.
See how in both notations, being specific is just specifying the lower bound as 0 or 1. Similarly, "one" can mean "zero or one" or "one or only one". You are leaving it unspecified because you don't know or don't care at this point in time. My conclusion, is that "many" can mean "zero or many" or "one or many" because it is ambiguous on purpose. It also doesn't match valem's solution, because an artist isn't tied to one song and can be reassigned to other songs. This doesn't match with the accepted solution, because it doesn't mean that one artist performs all songs like how king arthur inhabits all palaces. Wikipedia also uses the double bar, "one and only one" for one artist performing many songs.
According to this answer to another question about differences in crow's feet notation, it says "one" and "many" are ambiguous.
