Plot
With an evil laughter, the Pope of the Church of the Three Heroes receives a golden sword, ready to initiate Holy Judgment on the "fake Spear Hero" and the "Devil of the Shield." He raises the sword and fires a golden energy beam, which Naofumi barely could contain with his Shield, his arms going numb in the process. The Pope sarcastically says Naofumi is pretty tough for a "demon," that this was only a trial shot and thus the actual attack will begin now. Naofumi and the others watch as the Pope's sword, which looked like Ren's Sword, now takes the shape of a spear similar to the one belonging to Motoyasu.

Melty recognizes the Pope's weapon as a Cardinal Weapon Replica, which was crafted as an attempt to replicate the four Legendary Weapons into one ultimate weapon but had remained "lost" for centuries after its creation. With such power and fame, Melty adds that it was kept in secret by the Church, which had also fabricated its "disappearance" from the public. Naofumi questions why the Heroes are necessary if such weapon exists, to which Melty says that the mighty Replica uses up great amounts of mana per usage. Malty was shown to be completely in the dark about the weapon and its history with significance. The Pope compliments Melty's education over Malty's lack of discipline, and fanatically calls his treachery a "holy crusade of God against the fake Spear Hero and the Shield Devil." His devotes start offering their prayers to create a magic golden barrier. Naofumi asks Melty if she can neutralize the devotes, but she has no such power for it. Suddenly, Motoyasu stands up ready to fight the Pope and his selfish hero complex - much to the annoyance of Raphtalia and Filo. He fires a Lightning Spear attack, which proves ineffective against the Pope's barrier.

Seeing that lonely work will be useless, Motoyasu turns to Naofumi and accepts to teamwork. Malty and her companions combine their fire spells to Motoyasu's Spear into one deadly Burst Flare Lance attack, which also proves ineffective. Some of the Pope's devotes start to pass out in exhaustion from generating the barrier. The Pope keeps taunting their lower power level; Motoyasu attempts the Meteor Thrust, again to no avail. With a single swing of his golden Spear, the Pope launches another powerful holy attack, and Naofumi fears he won't be able to defend against such holy power. Suddenly, the Hundred Swords and Meteor Shot attacks come forward and effortlessly shatter the Pope's barrier. Revealing that both Ren and Itsuki are alive and ready to battle!

Ren launches his Hundred Swords attack again, to which the Pope orders half of his mages to focus on the barrier while the other half charges his weapon. Ren explains Motoyasu that he and Itsuki did not trust the Church so they started their own secret investigation. They found a classified file which was supposed to lead them to the burial site of the Cardinal Weapon Replica but actually led them to a fake shrine set to explode and kill them; the attempt failed thanks to the interference of Queen Mirellia's Shadows.

Itsuki claims that Nafoumi was also framed for taking his reward, but Nafoumi internally curses Itsuki for he accused Nafoumi and no one framed Nafoumi. Motoyasu finally starts to empathize with Naofumi, but Nafoumi didn't take it lightly for Motoyasu attempt to kill Nafoumi just a few moment ago, with no evidence to back his ideals. Ren and Itsuki attack, the Pope cannot defend against their strikes because his golden weapon has consumed too much mana and "deactivated;" Itsuki also says that the Queen's punitive force is coming so the devotes shall surrender in exchange for mercy. The Pope, however, doesn't surrender and urges his followers to keep fighting their "holy crusade" and thus the Queen means nothing to them. As the other Heroes unite, Naofumi refuses to join them, intending to fight alone with his own party, to which Motoyasu tries to reason with him.

Naofumi states that Malty is the one who is greatest guilty of the situation, with Motoyasu neglecting Malty's misdeeds instead of thinking by himself. Ren says that Naofumi is right, but the Shield Hero also calls out him and Itsuki on the bad consequences of their own wrongdoings. As Melty creates Aqua Shield protections for Naofumi's party, the Heroes start pointing out everyone's failed actions, but Naofumi further criticizes their own "Hero complex" getting into their heads due to the people's extreme trust on the Heroes, not to mention their lack of union against the Waves, Glass, and even the Soul Eater monster. Naofumi would not be surprised if everyone got tired of these Heroes. The Pope considers them a "disgrace" for fighting each other and launches a powerful Brionac attack to "cleanse" them.

Naofumi blocks the attack, disgustedly saying that both the Heroes and the Pope himself abuse their power for personal profit, but as much as he still doesn't forgive them, he agrees to teamwork with them in order to honor the promise made to Fitoria. With this, the four Heroes and their parties agree to fight together. Calling for God's power, the Pope and his followers cast the High-Level Multi-Caster defensive magic, Cathedral, which encircles them all while a massive dome shaped as a cardinal, as the Pope laughs maniacally at their fate and welcome them to his so called Cardinal..
