More about Rukia Kuchiki:

Rukia Kuchiki: Rukia is an unseated member of the 13th division of Soul Society and as such has no need of ever taking a potential dangerous or deadly mission all due to her adopted brother Byakuya's dealings and high rank within soul society. While she has been trained in the use of her Zanpakuto she is more highly skilled in the use of gigai (spells) and has admitted so on many occasions. On one of her early mission into the human world for a routine spirit burial she sneaks into Ichigo's bedroom and is quite surprised in his ability to see her but is interrupted by the attack of a hollow. After being mortally wounded in the battle she intends to transfer half of her power to Ichigo so that they may fight the creature to together. Unwittingly and unknowingly Ichigo absorbs most of her power and defeats the creature with ease but leaves Rukia very weak upon her return to Soul Society she is healed and taken to stand trial for giving Ichigo her power. It is here that the recurring aspect of her inability to fight results in her being saved by Ichigo, Byakuya and friends on multiple occasions.
