About UmaLoops

Find which four characters form the strongest Umamusume legacy loop.

What UmaLoops is, how legacy loops (parent loops) work, and how the planner ranks four-character rotations by compatibility.

What is a legacy loop?

In Umamusume Pretty Derby, a legacy loop (also called a parent loop, breeding loop, or inheritance loop) is a set of four characters that rotate through trainee and parent roles so each career step keeps strong affinity. UmaLoops ranks candidate quartets by compatibility across all four loop steps.

How the planner works

• Find Loops — filter by aptitude and collection, then open a ranked list of legacy loops.
• Your Loop — walk each career step, inspect lineage affinity, and rotate who trains next.
• Collection — keep the characters you own so pool filters stay personal to this browser.

Compatibility methodology

UmaLoops scores each ordered four-character loop by summing base compatibility across all four career steps (trainee + two legacies + sub-legacies as the rotation fills). Symbols use common community thresholds (△ poor, 〇 good, ◎ great). Rankings exclude G1 race-win affinity bonuses, which need trained veterans outside the catalog snapshot.
