The "Bleach" anime series adapts Kubo's manga but also introduces several original, self-contained story arcs. In Karakura Town, a 15-year-old high school student Ichigo Kurosaki becomes a substitute when Rukia Kuchiki, a Soul Reaper, cannot fulfill her duties after engaging in battle with a particularly powerful Hollow. Although initially reluctant to accept the heavy responsibility, he begins eliminating Hollows in Rukia's place and during this time discovers that several of his friends and classmates are spiritually aware and have powers of their own: Uryū Ishida is a Quincy who can use spirit particles, Orihime Inoue possesses a group of protective spirits known as the "Shun Shun Rikka" and Yasutora Sado ("Chad") has strength equal to the Hollows encased in his tough right (and occasionally left) arm.
