In Kamen Rider Saber Ep. 31: Believing in Strength, Strength Believed In, Rintaro was overwhelmed by his helplessness at his inability to save Mei! Being shaken by the strength of his own convictions, he flees from the Northern Base! Just then, the Megiddo that has taken Mei reappears and the growing fear that they may be unable to free her intensifies! Saber fights the Megiddo alone, and Mei is about to be separated from it, but her separation is still incomplete! Still, once again, Zooous stands before Saber, keeping him from accessing the Megiddo! Saber is facing a two-on-one battle, and occasionally the Megiddo reverts back to Mei and vice-versa mid-combat! Can they really save Mei in time? And what of Rintaro?
