Kenja no Deshi wo Nanoru Kenja

Synopsis

Despite the overwhelming numbers of monsters in three separate locations they are defeated by Luminaria, Cleos, Amalette and Mira. Before they can celebrate a crack opens in the sky and an immense black dragon appears through it and attempts to kill Solomon. Mira summons all seven of her Valkyries, tens of thousands of dark knights and Leticia to support them with healing magic. With the dragon distracted by her army Mira manages to paralyze the dragon while Luminaria hits it with an immensely powerful meteor strike. Somehow the dragon survives but Luminaria is left exhausted. The dragon attacks so to survive Mira summons Pam who casts every reinforcement spell she knows on Solomon, allowing him to resist the dragon and save everyone. Mira summons Eisenfald and the dragon is finally defeated. The kingdom celebrates but Mira refuses the official reward for killing the dragon, believing her identity should not be revealed to the public too soon and instead focus on her other goals of locating the Wisemen, dealing with Chimera Clausen and the approaching end to the inter kingdom peace agreement. With so many clues to follow up on Mira does not stay long and immediately sets out to continue her adventures.
