List of So I'm a Spider, So What characters

This is a list of characters appearing in the novel series So I'm a Spider, So What? (蜘蛛ですが、なにか？), written by Okina Baba and illustrated by Tsukasa Kiryu, and its anime and manga adaptations.

White

 * White (白) / Shiraori (白織)
 * Nicknamed "Kumoko" by the fandom. She reincarnated as an initially "Nameless" spider monster in the most dangerous dungeon in the world where she has to constantly fight to survive and slowly evolves into an incredibly powerful being, becoming known as the "Nightmare of the Labyrinth". She eventually escapes the dungeon only to get into a conflict with the Demon Lord, Ariel, before ultimately making peace with each other and starting to travel together, during which she ends up ascending to godhood after transcending the world's RPG system. In the prolepsis, she has acquired a human form and serves as the commander of the 10th demon army. Initially implied to be the reincarnation of the classmate Hiiro Wakaba, she is later revealed to have actually been just an ordinary spider that happened to be in the classroom when everyone was reincarnated and was implanted with the real Wakaba's memories by D. Following the revelation that the planet is dying, she forms a plan to save it by destroying the RPG system and using the freed-up energy to heal the world, indifferent that half of humanity would die from the backlash.

Ariel

 * Ariel (アリエル)
 * The current "Demon Lord" and progenitor of all spider monsters in the world. Though physically a girl in her early teens, she is actually one of the oldest beings on the planet. She confronts White after she finally escapes the dungeon and tries to kill her due to the damage she was inflicting to the spider monster species' hive-mind. However, after multiple failed attempts, the two agree to a ceasefire and start traveling together, eventually putting their grievances aside and building a very strong grandmother-granddaughter relationship. In the prolepsis, she wages war against humanity and is generally viewed as a tyrant. However, her warmongering roughly began to make sense following the main story's revelation that the planet is dying, since the world's RPG system gathers the energy of people's skills upon their deaths to heal the planet.

 * One of the classmates, nicknamed "Vampy" by White. She reincarnated as a vampire born to human parents due to a mutation.

However, over time, she developed a very close, sister-like relationship with her, to the point of becoming possessive. In the prolepsis, she offers manipulative assistance to fellow classmate Hugo and is later revealed to be an officer in the tenth demon army.

Gullie

 * Güliedistodiez (ギュリエディストディエス) / Black (黒)
 * A god who takes on the form of a man dressed in black armor and the ruler of the dragons, nicknamed "Gulie" by White and Ariel.

Ael, Sael, Riel & Fiel

 * Ael (アエル), Sael (サエル), Riel (リエル) & Fiel (フィエル)
 * Ariel's quartet of Puppet Taratects, small spider-type monsters that operate human-sized mannequins. Although initially enemies, they grow close with White after they start traveling together and she gave their mannequins a make-over, giving them an almost human-like appearance.

D

 * D / Hiiro Wakaba (若葉 姫色)
 * One of the classmates. She was initially implied to be White's past self and an otaku who was a victim of bullying. However, it is later revealed that she is actually a high-ranking god who was slacking off from her duties. She was the one who reincarnated her classmates after they were killed in an explosion, which was actually an attempt on her life by a previous Hero and Demon Lord, and created White by giving her memories to a random spider to make it seem like "Wakaba" had died, just to avoid being found and dragged back to work by her fellow gods. She is also the creator of the world's RPG system, which is a curse she placed on humanity after they nearly destroyed the world once, allowing them to develop energy in the form of skills that she takes back upon their deaths to slowly heal the planet. Throughout the story, she takes a more-or-less neutral stance, occasionally aiding White whilst also making the situations she finds herself in worse for her own entertainment.

After the timelines converge and he learns of the state of the world, he rejects both White's and Güliedistodiez's costly solutions and vows to find one where no one would have to die.

Already egotistical in his previous life, his new royal upbringing turned him into a megalomaniac who tried to assassinate Shun out of jealousy for his popularity, but failed and got stripped of his skills by Ms. Oka. However, rather than realizing the error of his ways like she hoped, this prompted him to make a deal with the demons to overthrow the Analeit Kingdom and attack the Elf Village as revenge, only to end up being brainwashed by White into aiding her group in their shadow war against the elves before being cast aside once his usefulness had run out. After the timelines converge and the brainwashing gets undone, he finally escapes from his megalomania and becomes repentant of his previous actions.

Sariel

 * Sariel (サリエル)
 * A high-ranking god who takes on the form of an angel and the true identity of the system voice, as well as Ariel's adoptive mother and Güliedistodiez's love interest. After humanity nearly destroyed the planet once by draining its life to use it as an energy source, she agreed to become the core of the world's RPG system so the people could atone for their sins by giving them skills to develop, which would be taken back upon their deaths and converted into energy to heal the world. However, at present, she is approaching her limit and is dying, which would kill all of humanity as well. Ariel and White plan to destroy the RPG system, which would save her whilst minimizing damage by only killing half of humanity, whereas Güliedistodiez and Dustin intend to let her die and for the former to take her place, maintaining the status quo but only delaying the inevitable.

Araba

 * Araba (アラバ)
 * A powerful earth dragon that inhabited the same dungeon as White. It encountered her several times and even destroyed her nest once, traumatizing her with its overwhelming power, but always letting her go due to not considering the spider to be worth its attention. However, this proved to be a mistake that would cost the dragon its life, as this prompted her to become strong and claim her revenge. Toward the end of their final battle, the earth dragon opted to let White kill it after being pushed into a corner, choosing to die with pride rather than struggle in vain.

Mother

 * Mother (マザー)
 * A colossal spider-type monster that gave birth to White. The two did not have a good relationship, with her trying to cannibalize her as soon as she was born, forcing her to flee, and later attempting to control her using a psychic link she has with her offspring. This prompted White to use their connection to eat away at her soul, slowly weakening her and prompting her to send her other offspring to attack her. During their final battle, despite being severely weakened, she managed to lure White and nearly killed her, only being defeated when she used her own stolen strength against her.

Potimas

 * Potimas Harrifenas (ポティマス・ハァイフェナス)
 * The Main antagonist of the series and the patriarch of the elves as well as Ariel and Filimøs' father. Initially presented as a supporting character in the prolepsis, where he helped Filimøs search for her students, he is later revealed to actually be a narcissistic mad scientist with a god complex who is obsessed with attaining immortality and drains the planet's lifeforce to power his inventions. In reality, he only helped secure the reincarnations to use them as guinea pigs in his experiments and even killed the ones he considered dangerous. Shortly after the timelines converged, he is killed by Ariel during the Demons' attack on the Elf Village.

Dustin

 * Dustin LXI (ダスティンLXI)
 * The pontiff of the Word of God religion who caused the war that destroyed Sophia's home in the main story and aided Hugo in the prolepsis. He has lived for centuries using a unique skill that allows him to reincarnate with his memories intact when he dies. Despite his horrible actions, however, he genuinely acts for humanity's greater good and is fully aware of how depraved he is, but already views himself as "irredeemable". He later takes on more of a supporting role by cooperating with White and Ariel to defeat their common enemy: Potimas. However, he is opposed to their plan to destroy the world's RPG system, as half of humanity would die from the backlash, and is secretly working with Güliedistodiez to stave off the collapse by sacrificing the gods instead, which would only delay the inevitable,

Afterward, however, Hugo brainwashed him and broke his mind to erase evidence of his involvement.

Afterward, Güliedistodiez gave its corpse to White to consume, believing it was what it would have wanted.

Hyuvan

 * Hyuvan (ヒュバン)
 * The ruler of the wind dragons. Despite its status as the ruler of its sub-species, it has a very punkish attitude, often causing it to get into comedic arguments with Ariel.

Reise

 * Reise (レイス)

Also, unlike the other dragon rulers, it was not created by Güliedistodiez but instead a result of an experiment by Potimas: a combination of his DNA with a dragon's.
