Ah yea i mis-read a line.

stonedzombie : Yea you missed it. That part was already explained in the soul society arc. In short :

Spoiler:

Ganju's brother was the 13th division vice-captain Kaien who got possesed by one of aizen's experimental hollows and then Kaien threw himself onto Rukia's zanpakuto to save Rukia. The whole bit about Rukia not telling Ganju or his sister about it was a melodramatic plot device to make Ganju and his sister hate Shinigami. The whole "Oh i killed my friend who was possesed and trying to kill me NO WAI he was trying to save me by using my sword to kill him before he killed me, im so emotionally distressed that i cant even tell his family the truth, i must pretend to be a cold blooded murderer instead and make them hate the shinigami i represent!" bit.
