Start with this
For Anime Origins how to get Gems, the ranked legitimate methods are codes first, repeatable wave farming second, income units such as Bluma for longer sessions third, and cautious AFK expectations last; this guide does not promote macros. The fastest documented gem start is to reach Level 10 and redeem Release! for 1,750 Gems and TYKaito! for 1,000 Gems. After that, repeat stages your team clears reliably, use Bluma when longer runs reward her Training Data income, and reinvest only part of the haul into banners. Exact gem-per-stage tables are not published yet, so compare your own completed runs instead of trusting a made-up hourly rate.
