Capture characters by following the fight, Crystals, capture, team, avatar, sword, and index checklist.
Use this mechanic explanation with safe capture steps, an upgrade checklist, and a clearly marked roster/rate gap. It is an evidence-backed capture workflow with fight, Crystals, team, avatar, sword, index, auto-catch, auto-sell, and roster/rate boundaries.
Defeat enemies, earn Crystals, capture available characters, place useful captures into your team, and re-check avatar, sword, index, and quest progress before spending rarer resources. The capture-and-team mechanic is official enough for a workflow; exact roster, pity, rate, drop, and best-unit details remain a clear evidence boundary.
