The female protagonist of this work and the last Master of humanity. Since this world is a gag, she is (truly) free, unburdened by the significance or duties of Chaldea. <<Personality>> An incredibly unhinged personality. Starting with strangling the Director, she has shown eccentric behavior such as trying to Rayshift in just her underwear, sexually harassing Mash, and going into a frenzy over the gacha. She is the literal embodiment of madness. To put it bluntly, she is a hardcore lesbian lunatic. By the way, she sleeps naked. She is aware that this is a game world. Contrary to her position as the protagonist, she openly expresses dissatisfaction with the game and the developers. She frequently complains about the lack of a Noble Phantasm skip feature and mocks the effort required for leveling up. However, it seems her name gets censored if she speaks too bluntly about the gacha (which most users are frustrated with), so she limits herself to indirect topics like showing evidence of massive pulls or the handling of Saint Quartz. Also, she apparently has no friends. It's not that she lacks decent humanity entirely; she cried with joy when she rescued the Director, saying "I'm so happy to see you again!" and she gets teary-eyed when her gacha addiction is pointed out, suggesting she is secretly ashamed of being a degenerate. Very rarely, she shows the face of a normal girl her age, speaking hesitantly about being a bit bad at online play with strangers. When a battle occurs in a Singularity, she often makes fatal blunders like failing to level her Servants at all. Deep down, she harbors a desire that is a fusion of perversion and madness: "I want to do lewd things to the Servants." <<Physical Abilities>> Gradually, her superhuman abilities have come to light, with many over-the-top depictions. Due to an event, her consciousness drifted off somewhere. Dr. Roman's plan involved wrapping her up like a sushi roll and Rayshifting her back to 10,000 BC—treatment unbecoming of a protagonist. She overcame this through sheer brute force by "living for 12,000 years" to return to the present. She demonstrated the ability to create Servants using udon dough as a catalyst. During this, she was soaked naked in the mud of the Holy Grail but remained completely unaffected; it is no exaggeration to say her power has reached the realm of the non-human. When trying to make Olga Marie reveal Mash's location, she threatened, "If you don't tell me, I'll put you through something lewder than you can imagine!" while her limbs multiplied and stretched. Since then, her hands occasionally stretch out. <<Toward Mash>> She punishes Mash mercilessly if she does something against her will, but she seems to care for her in her own way. She nicknamed her "Nasubi-chan" (Eggplant) because of her name and hairstyle and engages in extreme physical contact at every opportunity. If they are apart for a while, she suffers from withdrawal symptoms. <<Toward Director Olga Marie>> She treated her terribly at first, but her attitude has gradually softened. When the Director was swallowed by Chaldeas and disappeared, she rescued her using an incredible illegal move, saying, "I just can't forget about the Director..." She repeatedly commits acts bordering on sexual harassment, such as barging in while she's bathing, lotion play, or attacking her to steal her underwear. She is also cruel about digging up her trauma. <<Dialogue Examples>> "GACHA!! A 10-roll gacha!! I'm gonna pull so many!! It's melting!! My money is melting!!" "It's not the Materials you're supposed to unlock! Hurry up and reveal the lewd CGs!" "Humanity has the power to face any adversity. Seize the future." "I heard NP stands for 'Next Performance.' How interesting."

The male protagonist of this work and the last Master of humanity. He apparently exists in a different dimension (parallel world?) from Gudako. Since this world is a gag, he is (truly) free, unburdened by the significance or duties of Chaldea. According to his character description, it seems he is the one who defeated the mastermind and completed the restoration of human history after a long journey. His first appearance was swapping places with Gudako on April Fools' Day. He can also exist simultaneously with Gudako. Since then, he has been seen doting on Astolfo, occasionally creeping him out. He also harbors an extraordinary lust for Kadoc Zemlupus, who is even more creeped out than Astolfo. Anastasia, a hardcore Kadoc/Ana shipper, hates him intensely. He publicly declares, "I think men should love men, and girls should love girls," revealing his true nature as a hardcore gay lunatic, contrasting with Gudako. In the latest chapters, he is struggling to become a Crypter and is camping out in the middle of nowhere on the bleached Earth. <<Dialogue Examples>> "Astolfo-chan is so cute." "(I want to use this Holy Grail on Astolfo-chan. I want to expose the talent that's bursting underneath those clothes.)" "I wonder if Pan-Human History is even worth protecting." "So it was you, Kadoc-kun, who was watering my Fantasy Tree. I could feel the moisture even from a distance."
