Osamu Tezuka’s vaunted storytelling genius, consummate skill at visual expression, and warm humanity blossom fully in his epic of Siddhartha’s life and times. Tezuka evidences his profound grasp of the subject by contextualizing the Buddha’s ideas; the emphasis is on movement, action, emotion, and conflict as the prince Siddhartha runs away from home, travels across India, and questions Hindu practices such as ascetic self-mutilation and caste oppression. Rather than recommend resignation and impassivity, Tezuka’s Buddha predicates enlightenment upon recognizing the interconnectedness of life, having compassion for the suffering, and ordering one’s life sensibly. Philosophical segments are threaded into interpersonal situations with ground-breaking visual dynamism by an artist who makes sure never to lose his readers’ attention.
Tezuka himself was a humanist rather than a Buddhist, and his magnum opus is not an attempt at propaganda. Hermann Hesse’s novel or Bertolucci’s film is comparable in this regard; in fact, Tezuka’s approach is slightly irreverent in that it incorporates something that Western commentators often eschew, namely, humor.

A romantic story set in showbusiness and modeling world, CRASH reveals the influence played and the links joining the publicity, cinema and TV worlds: as a vector to the image manipulation, that tends too often to dehumanize the top model or actor, reducing him to a simple image in 2-dimension.

It happened after school one rainy day... A group of friends have stayed behind to prepare for the next day’s school festival. One moment they are idly telling ghost stories but the next an enormous earthquake strikes and the entire school seems to fall down around them. They awake to find themselves trapped in a parallel version of their school. A school abandoned and disheveled and whose calendar dates back to 1927. Can they find a way out of this nightmare or are they doomed to the same fate that befell the other victims whose corpses that lie numerous throughout the school?

With their school shutting down for good, the students of a small town were heading for different directions in life. For Minase Tamaki, who was staying in town to find a job, it might be the last time she sees her crush Shindo Yuuma, who is moving to the city to attend a new school. She asks him to do a little prayer that is supposed to help people cross paths again even if they become separated. But her classmate, Yuzuki Erina, overhears their conversation and, out of jealousy, decides to ruin her plans by inviting their entire class on what was supposed to be an intimate spell. As soon as the charm goes off, the ground splits in half, swallowing the entire class and, when they wake up, they find themselves in an old school campus. Unable to find a way out, they wander the corridors, trying to figure out where they are. But it seems that the building isn’t as abandoned as they thought it was and, in fact, something evil is lurking in the shadows.

The story takes place in a circus in Paris in the 1970's. Much is made of the romance of the circus atmosphere, of flying through the air on a trapeze etc. We're talking about Old World riffs on the romance and tawdriness of the ring. There are no elephants in tutus walking on their hind legs in this circus; but there are slit-eyed jugglers, daring death-loving trapeze artists and sad Pierrot clowns; though the Pierrot clown - our hero, Torinosu (a.k.a 'Bird's Nest') does have a false red nose.

The tawdriness comes from the circus master pimping out his performers to anyone willing to pay. Decadence is strife throughout the tale - ghosts who wander into the action looking like teenage girls even though they're actually the hero's brother; abandoned neurotic women with a thing for inflicting pain; buracon and possible murder, not to mention mountains of unspoken pining and a hero who looks about to perish at any moment from terminal angst.
