Unfortunately, this method had a high failure rate. Fourfold Spring required a critical hit to heal, and with Midnight Exile, she didn't lack for critical hits. The problem, however, was that she didn't have it on hand.
Pine Bloom was too quick, and each time, she took away 30% of Rita's health. To survive, Rita would need to raise her health by at least 31% before the final blow from Pine Bloom.
100% → 70% → 40% → 10% → 0%.
This meant Rita needed to raise her health by 21% before Pine Bloom killed her, which would require 6 critical hits to guarantee it... But Pine Bloom could kill her in under two seconds.
Six critical hits in two seconds?
Even if Sea Pony was willing to stand still and let her hit, it was impossible.
After ruling out all other options, there was only one left—[Behind the Scenes].
In this special time-altered space, Rita could lower her health to below 5%, then use Mysterious Power and deactivate [Behind the Scenes].
