Anime Origins Rifts guide quick answer: Rifts are late-game, 30-wave community content rather than a first-session farm. Public gameplay walkthroughs repeatedly show the Shibuya Metro Rift, a train stopped by rubble, and extra enemies leaking while that rubble remains. Build economy first, place a multi-placement unit on each rubble point, keep your main damage and Hill/air coverage near the back, and do not queue with an under-leveled Story team. Exact spawn timing, token rewards, pity, shop prices, and Secret-unit drops are community-reported and may change after a patch, so read the live Rift panel before spending or farming.
