For the Sosuke Aizen rate-up

BLEACH Mirrors High summon calculator

A rate-up pull gives the featured character 1.5% of the time and any 4★ 3%. Every 10th pull is at least a 3★ or better, which leaves those odds where they are. Each pull pays 1 Rate Up Medal, and 200 Rate Up Medals buy the featured character outright.
