I'll use Draciel's topic as guide, it's sooo much detailed. ^^
Name: Kurokaze Giovanni
Age: Seems to be 18, to anyone that looks.

Dislikes: Heat, people who seek revenge while say it's justice, destroying trees.
While was a teenager, discovered how to use his little spiritual power. Quickly developed ways to control it with remarckable efficiency, using very little spiritual power to materialize things, such as small walls and piercing shards. All these things were translucid and purple, as his spiritual power. After two years of confronting really weak hollows that sometimes attacked him, he was killed by a Menos Grande, which, by the way, wasn't there to attack him. The menos wanted a nearby shinigami. The shinigami sent Giovanni to soul society after this, where he became a shinigami, gained quite much spiritual power, and learned his Zanpakutou's name: Kamaitachi, the incarnation of razor winds. He developed a way to 'refine' spiritual power, allowing him to enter the 12th team of Gotei 13.
Search an image of Kamaitachi. I don't know how to say 'doninha' in english, but it's one of these, a white one, with a huge scythe.
Shikai - Kamaitachi
His sword becames an rapier: can't slash, just pierce. However, his zanpakutou's ability is to make wind cut things, so, the rapier may be enveloped by a thin wind shell, that cuts in any direction. He can also send a kind of 'getsuga tenshou' made of wind, although it is not one big slash, but millions of minimals slashes. Also can do this while piercing, this way shooting wind like bullets.
Bankai - Kaze no Kamaitachi [Wind Kamaitachi]
Quite redundant, sure. When bankai is activated, the rapier becomes the giant scythe. Even it's holding can be used to cut. As it's Kamaitachi itself holding the scythe together with Giovanni, the scythe makes movements even faster than the rapier. Giovanni can throw the Zanpakutou, then Kamaitachi will fight alone [kind like the scythe is moving alone]. The most destructive attack is Tatsumaki, when Kurokaze spins the scythe over his head than throw it, causing a huge hurricane to start cutting everything in it's way.
Shunpo - It's his strong point. One of the fastests in Soul Society.
Sword Fighting - While on close combat, it's more a defensive style. With a bit of range, he uses his long-range cutting attacks. However, if needed, attacks in close range. It's a quite exibicionist style.
Hand-To-Hand - Blocks attacks, mainly, with concentrated refined spiritual power.
Demon Arts - Most of them are defensive ones, apart from byakuray, which he uses only in emergencies.
Reiatsu - Has below average reiatsu, however, with his technique, he can use very little reiatsu to do everything people tend to use huge amounts.
Natural Speed - Much above average
Natural Strength - Below average
That's it. ^^
