Member of squad zero
Yamada is a very nice person, but also has a dark side. He literally can't hurt a fly that hasn't annoyed him in any way, but anything or anyone that annoys or insults him is an enemy.
He will always help someone in need, no matter what it is.
Zanpakutou:
Type: speed and time
Name: Suraisā (slicer)
Release command: Furīzukatto (Freeze and cut)
Special abilities: When Yamada releases Suraisā, it splits up and wraps around his arms and feet and become blades which he uses to cut his opponents with. It also enhances his normal walking speed to that of flash step and allows him to completely stop time for a total of 10 seconds, but during those 10 seconds he cannot cut his enemy, or he will suffer a huge amount of pressure on his body eventually causing him to faint or die.
Appearance: It looks just like an average katana when not released.
Yamada was born into a life of misery as his mother died at his birth and his father left him and his sister to die on the streets when he was 10. One day, while he was searching through a dumpster for food, he saw a huge monster running after a little girl, as the girl shouted for someone to help her, he knew he would regret following to save her. Just as he was about to jump the monster, a guy in a black robe appeared and cut the monster's head off with a sword faster than he could say "Who are you?". The man turned to him and said, "here, i'll perform konso on you.". He stuck the blunt of his sword to Yamada's forehead and he started sinking into the ground. "Wait!" Yamada shouted, but it was already too late.
After having lived in Rukongai for a while, stealing food to survive, he was approached by a group of shinigami who had watched him for a while and asked him to join the shinigami academy.
When he graduated from the academy 2 years later, he was recruited into squad zero and was told to keep it a secret from everyone else.
