Warning: Exploring this aspect of the So I'm a Spider, So What? Wiki contains heavy spoilers.

D is an enigmatic, high-ranking god, who is also one of the administrators managing the System of the other world that the reincarnations end up in.


For majority of the series, D has intentionally hidden and concealed her identity and appearance, preferring to communicate to characters in the series indirectly either using a summoned smartphone or via telepathy. She is typically depicted visually in the manga as a female figure with at least shoulder length hair shrouded in the shadows with a devilish grin.

It is only in volume 9 of light novel do readers get an accurate description of her appearance. D has the appearance of a high school girl with waist-length straight black hair and eyes of various colours (includes black, gold, and red). Her normal outfit consists of a school uniform and a pair of glasses (LN - other sources may differ).

To Sariel, she appears as a girl one step short of being an adult with an expressionless face that makes one think of bottomless darkness.[2]


I wish you'd phrase that a bit more flatteringly. You could say that I'm malice incarnate, for example.

— D

D cares more for her own personal amusement than anything else, but she's described to speak in a voice devoid of emotions. She is a playful self-proclaimed "Ultimate evil god", and most of the time states that she does things simply for entertainment.

She appears to have a sadist trait, as she has stated she enjoys watching and toying with Kumoko.


D was first indirectly introduced as a silent figure who was spectating the adventures of the main character and enabled the creation of Kumoko’s Wisdom skill after hearing her short rant in the labyrinth. She later intervened and gave a short introduction about herself to Kumoko, when another administrator tried to investigate Kumoko after the death of a fire dragon.

She appeared later again using a smartphone to congratulate Kumoko for evolving into a Zana Horowa, a first of her kind unique spider monster that has an innate immortality skill. It was also at this time, D divulge some information to the reason behind Kumoko's reincarnation into the world. That she was the one responsible for bring the Japanese reincarnations into the other world, and she was indirectly invoked in their demise as the mysterious explosion that occurred in the beginning of the series was caused by a combined dimension magic spell from the previous Hero and Demon Lord from the other world targeting her.

Hence, D decided to collect souls of the unintentional victims, and equipping them with the mysterious n% I = W skill, which allows them to but is not limited to giving them Level Up regeneration and integrating the class and Ms Oka into the system. She also gave each student a custom Skill according to her perception of them and reincarnated them into species that best matched the wavelength of their souls.[1]

D reveals to Kumoko she was in the classroom at that time of explosion.

D collecting the Japanese souls and transfer them over to the new world.

It was later revealed she is also responsible for the creation of the System, a complex planetary-scale conjuring that allows the inhabitants of the world to use skills and helps with the usage of magic. She obliged the request of Güliedistodiez and created the System as a way for the planet's inhabitants to earn the energy needed to restore the planet on their own. The System itself, though, is a double-edged sword that was implemented in part due to her curiosity and sadism.[2]


D views Kumoko with a sadist perspective, taking enjoyment and amusement in seeing her struggle for survival and beyond. While she is not considered the series’ main antagonist, she has on occasions both directly and indirectly placed obstacles in Kumoko's path, never making it easy for Kumoko to accomplish her goals. D has maintained a near non-interference policy to the other world and newly arrived reincarnations as she is considered an outsider though she is quick to break her stance if her actions will result in more entertainment. D can be considered fond of Kumoko, after learning about her constant struggles and near-impossible survival in the harsh dungeon. She has given Kumoko numerous minor assistances in her journey, such as granting Kumoko's request for a new skill, Wisdom; granting her the title, Champion, and giving her hints about the future.
Güliedistodiez or Gülie for short is a fellow administrator of the other world. He is considered an acquaintance and an indirect subordinate of D. Despite being the original creator of the system, D left the heavy responsibility of maintaining and troubleshooting the System to Gülie. Despite the planet technically not being under D's jurisdiction, D has left him a few restrictions, that can be seen as hampering his abilities in controlling the planet. While Gülie is grateful for D's assistance in creating the system, he is also annoyed by D's constant interference in the other world's affairs.
Despite being fellow administrators, D and Sariel do not share a friendly relationship. While Sariel's animosity is mostly instinctual, due to her being an Angel, D dislikes her for more personal reasons, viewing her and her entire race as "muscle-heads".
It is implied that the reason why Fei was reincarnated as a Wrym – a species D looks down on – because she took issue with how she treated Wakaba Hiiro in their past lives.


It is hinted that D is one of the strongest gods in the multiverse - many gods are afraid of her and do not dare to enter places that are under her jurisdiction. The lack of Dragons on earth is implied to be caused by her presence there.

  • Physical Strength beyond the System: As a god and an administrator of the system, it is assumed her stats would be above the System's limit.
  • Intelligence: D has displayed an almost omniscient level of intelligence, being able to perfectly predict other people's thoughts to the point where they wonder if she is reading their minds.
  • Conjuring: D has displayed the greatest feat of conjuring in the series: creating and designing the highly complex System with seemingly little effort.
    • Counter-Measure Resistance: D's conjuring is so strong that it was completely unaffected by Potimas' anti-system barrier.
    • Dimensional Manipulation: D has also shown to the ability to freely manipulate space. With her primarily been shown to use this ability to transport a smartphone to Güliedistodiez in order to communicate with him while still remaining at Earth. As a God, its likely that D herself can also go to any dimension or planet she desires with a thought.
    • Item Creation: D has also shown the ability to create items out of nothing. With her primarily using this ability to create a smartphone in order to commnicate with Güliedistodiez.
    • Aura of Terror: The mere act of using conjuring makes D give off a frightening aura that terrifies even fellow gods.
    • System Manipulation: As the creator of the system, D can freely alter it however she pleases, allowing her to, for example, make new skills.
  • Immortality: As the God of the End, it is expected she will still survive till the end of the universe.
  • Telepathy: She can communicate with Kumoko by reading her mind.
  • Darkness: Appears as a vast field of darkness when perceived by Gülie
  • Stealth: Although weaker than Meido in direct combat, she is skilled at evading detection.
  • Miscellaneous Skills: As stated by herself, D can do "anything" if she sets her mind to it, even without her conjuring.


  • In the Web Novel, she owns a wide variety of powerful and pointless magical artifacts. Such as a cursed set of playing cards and a one-time use baseball bat that can destroy powerful magical barriers.
    • The former was accidentally used to curse Sophia so that she can only refer to Shiraori as "master".
    • The latter was used by Shiraori to destroy the barrier that surrounded the Elf Village.
  • She has a general dislike toward dragons.
  • She is known to be an avid gamer.
  • Her voice actor voiced Visha from Youjo Senki and Fubuki from One Punch Man among others.
  • D seems to dislike woman with larger chests than her, intentionally "setting" the reincarnates to be smaller than her.
    • Sophia and Karnatia are exceptions who "might" get larger, which is exactly what happened.
    • This is also why Shiraori, who shares D's looks, is the third largest amongst the reincarnations.
