Bleach Manga 001-564

Ichigo Kurosaki is a teenager in Karakura Town who is gifted with the ability to see spirits and has his life changed by the sudden appearance of a girl named Rukia Kuchiki. Rukia is a Soul Reaper—one of many entrusted with the preservation of flow of souls between the World of the Living and the Soul Society from where she originates from by fighting Hollows, dangerous lost souls who consume other souls. When she is severely wounded defending Ichigo from a Hollow she is pursuing, Rukia transfers a part of her Spirit Pressure energy to enable Ichigo to fight in her stead as a substitute Soul Reaper while she is forced to remain in the World of Living until she can recover her strength.
