Idol Rabier/Chronology

Volume 4
Rabier attacked the Van Reichnott mansion and accused him of giving asylum to the "devil of the shield." His soldiers rampaged the mansion until Melty shows up. Melty demand them to stop their action and take her to her father. He took both Melty and Reichnott to his mansion.

Rabier tortures Reichnott, demanding him where the Shield Hero is. He threatens to torture and kill Melty if she does not spill the beans either. At this moment, Naofumi and his team barge into the room, disarming the soldiers, rescuing Melty, and cornering Rabier.

At this time, Raphtalia walks up to Rabier, sword in hand, taking on Rabier's whiplashes. She is about to kill him, as revenge for all his abuse against his underground slaves. Then Naofumi asks her if this is what she really wants to get closure, saying that she must have gotten stronger in 'other ways'. Raphtalia withdraws her sword and says that killing Rabier would make her no different from him, but that he will atone for his sins in other ways.

But then, Rabier pulls out his own rapier sword and disarms Raphtalia. She gets out her backup mana sword and stabs him completely through the chest. Rabier then stumbles back, drops through the window, and falls several stories to the ground.

Raphtalia and the team then enter Rabier's underground prison to confront Raphtalia's past. Raphtalia and the team free some of Rabier's enslaved ajin like Keel, but find that her childhood friend Rifana is a dead skeleton, after years of Rabier's torture. In Raftalia's flashback, Rifana says her last wish is to marry the Shield Hero, who will protect the ajin. Another flashback reveals that young Raphtalia was only able to escape the prison fate because she was sold to a slave merchant (the one Naofumi buys her from). Raphtalia and the Shield Hero Naofumi agree that they must protect the ajin so that no ajin ever has to experience what Raphtalia and Rifana have at the abusive hands of Rabier.

Upon returning above ground, they find Rabier is still alive. He prays to a monument seal and releases a zombie dinosaur monster demon (Tyrant Dragon Rex) from underground to kill the Shield Hero and ajin. The dino demon steps on Rabier, crushing and seemingly killing him, and Naofumi and the team are tasked to defeat the dino demon themselves.
