Mephisto is a boss in part 2 of Paradox. She joins when the party requires her aid to take down a large group of Golem Girls.


Defeat her at her Magic Academy. Following the story afterwards, the party is tasked to head into March Hills in order to reach Grangold. However, the entrance is guarded by a platoon of Golem Girls. In order to get past them, the party is told to head to the Poison Swamp (East Gold), where Mephisto is found.


Her first action upon joining the party is to destroy a large group of Golem Girls in March Hill, although the party receives a nasty surprise at the end when another one wait for them at the end and forces the party into a fight.

When the party tries to question her further on what's actually happening in Grangold, Mephisto reveals that the Monster Lord didn't reveal more to her either, merely that she's indeed using both countries to destroy each other as it was a possibility in the real history.

When the party reaches Grangold and manages to fool Ant Girls by pretending to be brainwashed, Mephisto inform them that their next contact is with a mafia don in the tavern. When Sonya notices that their contacts often happen to be located there, Mephisto remarks that it is because the undeworld often has ties with brewery.

Just like everyone, Mephisto is absolutely dumbfounded by the reveal that the mafia don who are revealed to be Lazarus and Merlin are part of Sonya's family. However, the deal proceeds smoothly as Mephisto gives out titles for properties in Grand Noah in exchange for the mafia's service. She then remains silent for most of the raid on the castle, only confirming one of the prisonner that the operation to stop the war has indeed started. She's as surprised as anyone to see Queen Ant imprisonned, although it does confirm that the Lilith Sisters are the ones responsible for the operation.

After the party escapes victorious from their encounter with Lilith and a Tamamo No Mae from another world thanks to the intervention of the twins, Mephisto is seen at the victory banquet where she says she will continue serving Grand Noah just like she did, as she commits to her engagements. She doesn't comment on the sudden projection of the Monster Lord appearing to declare war, and is as surprised as everyone that there doesn't seem to be any movement from the Monster Lord's army the next day.

She stays under the radar for most of Grangold's sidequest, only talking once again when the party is in Gold Cont. West Tartarus discussing with Heinrich andAlicetroemeria when she inform the group that the world is under attack from the Monster Lord's armies, forcing the party to leave their host and start fighting through the human capitals to save them.

Once done, she has come with a plan to stop the assault that involves Luka taking down the leaders of the Monster Lord's armies: Queen Mermaid, Spider Princess, Queen Elf, and Queen Vampire. In the meantime, the heroine ask her and the human leaders to find more information about the Six Orbs and the Garuda Girl so that the party can reach Hellgondo.

She plays a minor role in "The Land of Night and the Heroes of the Seven Worlds", as she serves of messenger and brings news of attacks at the party tries to step in to solve the different issues.

With Cornelia:

Cornelia: "Mephisto... You didn't return the book you borrowed from the Monster Lord's Castle, did you?"

Mephisto: "Now that you mention it, I had completely forgotten about it. I'll reprint it, can you wait a little longer?"

Cornelia: "Really... Is that the language of someone in the teaching profession?"

Mephisto: "I take anything I can because it is my doctrine..."

Cornelia: "I see, you're now prohibited from entering the library."

Lily: "Rumor has it you're also a dubious character. You're better at wicked deeds then you are with magic, aren't you?"

Mephisto: "Both of those are practically the same thing. Magic is nothing but a wicked deed, and brings no happiness to people..."

Lily: "Hmph, I wonder what you're insinuating...?"

With Shirohebi:

Shirohebi: "Mephisto... You are a confidant of the 15th who has slipped into a human royal family."

With Witch:

Witch: "Mephisto, the most famous magician in the world... I want you to show me your best magic."

Mephisto: "Aren't you quite famous yourself? You're the most outstanding magician among succubi..."

Mephisto:" Yes, I am looking forward to it as well. Please don't go too hard on me... fufu."

With Grand Noah Queen:

Mephisto: "Your Majesty... Why have you trusted me thus far? Have you not considered the possibility I could betray you at the last minute?"

Queen of Grand Noah: "I believe you... Is that what you wanted me to say?"

Mephisto: "Yes, of course..."
