Bleach Vol. 15 — Manga Raw / Buy Official

The cold-blooded Soul Reaper barring Ishida's path—Mayuri Kurotsuchi—is revealed to be the very man who butchered the grandfather Ishida revered as his mentor, using him as an experiment. As the truth sinks in, uncontrollable rage and a thirst for vengeance blaze inside the Quincy. Heedless of his own life, Ishida unleashes power beyond his limits and looses an arrow at Mayuri, igniting a savage duel of hatred and pride against the mad scientist. At the same time, having learned just how vast the gulf is between himself and Byakuya, Ichigo throws himself into an insane, brutal regimen to master bankai—the final form of his zanpakuto—in just three days. With the hour of Rukia's execution bearing down, every resolve is put to the test.
