The Misfit of Demon King Academy II Episode 2

"No matter how many handicaps you have, it won't be enough. After all, you are going to challenge me!"

- Anos to Ziek Ozma

The Demon King's Duel of Intellect (魔王の知恵比べ) is the second episode of The Misfit of Demon King Academy II anime series.

Synopsis
Anos and his classmates search around Demon King Academy for the "Child of God." While Anos' comrades are fending off the attacks from the demons of two thousand years ago, Anos himself faces the King of Death's Army Officer, Ziek Ozma, in a duel of intellect. Anos must speculate who the Child of God is in this duel and make the correct guess. However, the number of times he can make his guess is limited. What was Anos' answer, and what is Ziek's motive ― ?!

Summary
Anos is challenged to a game of wits by Ziek, with the loser's magic being sealed for five seconds. He is given 18 tries to find who the Child of God is, but Ziek can lie once to confuse him. Anos accepts and willingly drops it to nine to make it "fair" for Ziek. He plays the game, but it's full of unescapable contradictions. He concludes that Ziek has fake memories, but it's too late, and Ziek summons his henchmen. Anos opts to forfeit, allowing Ziek to kill Melheis. However, even without his magic, Anos defeats the henchmen. Melheis is also revealed to be alive, as Anos used the spell Eleonore to create a pseudo-source and swap it with Melheis's source before the game began. Ziek attempts suicide, but Anos reincarnates him as his owl familiar to answer his questions.

Elsewhere, Lay cuts the tip of Gerad's sword before it can stab Misa. When questioned about his motives, Gerad reveals that Misa is the child of the Great Spirit Leno and thus has the power to control all spirits. He summons the Magic Shield Gennias, and when Lay strikes him from behind, twice the pain is inflicted back on him. He attempts to destroy the shield, but after breaking one of the shield's four gems, his source is destroyed as well. However, unbeknownst to Gerad, Lay is the reincarnated Hero Kanon. His seven sources allow him to destroy the shield without dying. Lay stabs Gerad, but commits suicide and reincarnates before answering how he got Misa's father's sword.

At Elio's castle, Eleonore and Zeshia confront Zabro Gaze, who has turned their classmates from the Hero Academy into gools. He tells Eleonore that the gods played a part in her creation, as they wanted to create a vessel strong enough to carry their power, which resulted in Zeshia's birth. The girls flee and find the big monument turning people into gools, but Zabro finds them and uses Jino Gleanus to drain their magic power. However, Eleonore uses Aske and her spell form to create pseudo-clones that supply her with magic power. She then fires a powerful blast that defeats Zabro and the monument. She heals everyone afterward.

Lastly, Rinka tells Misha that she was brought forth by the will of a god, who had modified the spell that separated her and Sasha into two, creating a personality that should have never existed. And she will dispose of her before she awakens. Rinka uses her invisible sword to strike Sasha at a distance, but her Phoenix Robe heals the wound. Sasha shoots four Jio Graze, but Rinka cuts through them and pushes Sasha back, accidentally impaling herself with the invisible blades that Rinka set up prior. Misha attempts to bind Rinka, but she breaks free and pierces Misha with her sword. However, Misha picks herself back up and summons a functional copy of Delsgade, the body of a god. Misha's eyes glow as she transmutes Rinka into a snowflake.

Adaptation Notes
Differences from the light novel:

Duel of Intellect
In the LN, Anos asked variety of different questions compared to the anime, as he used them as a means of trying to deduce the Child of God's identity. Originally, Anos was allowed sixteen questions and eight guesses, but that was later changed to eight questions and three guesses in order to accommodate Anos' request.
 * First Question: What do you (Zeke) know about the Child of God? WRONG GUESS
 * Answer: The Child of God has three possible candidates: Misa, Zeshia, as well as Misha and Sasha's fused form. Each of them has a specific origin that could make them the Child of God.
 * Misa Iliorogue was born fifteen years ago, as the biological child of the Great Spirit Reno and Shin Reglia, the right hand of the Demon King. This birth was exactly as the Heavenly Father God had intended. Misa’s lore as a spirit was and is the order to destroy the Demon King. That lore was spread not through the Human Realm or Demon Realm, but through the Divine Realm. Now that Anos had reincarnated, Misa is finally ready to awaken and follow her order.
 * Due to the deal made between Nousgalia and Jerga, the Heavenly Father God agreed to turn the Azeshion hero into magic second only to the order of the gods. However, in order to allow that because of his order, Jerga agreed to turn part of his source into the Eleonore spell, which continued to mass-produce source clones in order to birth a vessel of god. After countless source clones were created, the vessel was finally born and that vessel was the little Zeshia accompanying Eleonore.
 * During the Magical Age, Hero Kanon had one of his source fused with Ivis Necron, with their research into source/fusion magic proceeding smoothly, as Kanon was trying to strengthen demons to make sure to minimize casualties in the upcoming war between demons and humans. Sasha Necron had her source split into two by the Dino Jixes spell, as she was supposed to possess a single personality. The gods changed the spell's magic circle to give birth to Misha Necron. If left alone, Misha would disappear. Kanon realized that he was incapable of saving the sisters, as he left that task to Anos, who would soon reincarnate.
 * Second Question: Is there only one Child of God? WRONG GUESS
 * Answer: Yes.
 * Third Question: Are Misha and Sasha the same age?
 * Answer: Yes, since they were born on the same day.
 * Fourth Question: Has Nosgalia assimilated with Eldmed?
 * Answer: Yes.
 * Fifth Question: Who is the Child of God?? WRONG GUESS
 * Answer: There are three candidates for the role of Child of God: Misa Iliorogue, Zeshia Bianca, and Misha and Sasha Necron. In the Necron sisters’ case, the possibility lies with their fused form.
 * Sixth Question: Who is the Demon King of Tyranny?
 * Answer: Eldmed.

Other Differences

 * In the novel, Gerad approaches Misa when she's with Anos and everyone in the group. It was Anos who suggested that Lay accompany them, as he didn't fully trust Gerad.
 * In the anime, the Duel of Intellect is done using cards to help visualize the competition.
 * In the novel, Ziek was disrupting Anos attempt to revive Melheis by cutting his Rivide spell with a demon sword. In the anime, this is omitted.
 * In the anime, Anos reduces the amount of questions and guesses he is allowed in order to give himself a handicap to make the Duel of Intellect more fair to Ziek. In the novel, he did so that Ziek would give up his demon sword in case he would attempt to cut the Rivide spell at the cost of his life.

Duel of Intellect
To prove the answer is not Misa, Anos makes the following guess: Thus the lie must be between either guess five or six. He also thinks of the fused form of Misha and Sasha, who also has the eyes. Thus Misa is not the Child of God, and Anos is left with the unnamed fusion of Misha and Sasha. The clues point to the unnamed fusion, but Anos should know the name of the Child of God, so there's a contradiction. Because of this, Anos recognizes the game is rigged.
 * Guess 1: The Child of God is one of Anos' subordinates. CORRECT
 * Guess 2: The Child of God is Misha. WRONG
 * Guess 3: The Child of God is Sasha. WRONG
 * Guess 4: The Child of God is Zeshia. WRONG
 * Guess 5: The Child of God is Misa. CORRECT
 * If Ziek lied and Misa is not the Child of God, then none of his subordinates would be the Child of God. So there would be two lies, which is not possible.
 * If he lied for guesses 2, 3, or 4, then Misha, Sasha, or Zeshia would be the Child of God. So there would be two "Children of God", which is impossible.
 * Guess 6: The Child of God has the Demon Eyes of Destruction. CORRECT
 * Guess 7: The Child of God is not a pure demon, but a half-spirit, half-demon. WRONG
 * Guess 8: Anos doesn't know the name of the Child of God. WRONG
