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

Filimøs “Oka” Harrifenas, formerly known as Okazaki Kanami (岡崎香奈美), is the former homeroom teacher of the class that was reincarnated from Japan. Reborn as the daughter of Potimas Harrifenas, the ruler of elves, she roams the world in search of her students, using a unique skill that provides her with information about reincarnations.

Appearance[]

Ep8 Anime Ms Oka Japan

Okazaki Kanami

Okazaki Kanami was characterized by her petite figure and twin ponytails. In the anime, she is often seen wearing a white frilly jacket, a maroon-colored skirt that falls below the knee, and half-frame glasses.

As a young elf, Filimøs has a slim, childlike appearance. She has blonde hair styled into twin tails and blue eyes, giving her the classic look of an elf. When someone comments on her small stature, Filimøs explains that she hasn’t entered puberty yet and believes she will have a growth spurt—unaware that elves naturally have small and slender bodies.

Personality[]

Even before her reincarnation, Okazaki-sensei (Filimøs) was known for her peculiar way of speaking, which she continues to use after being reborn. Becoming a teacher was her childhood dream, and to achieve that, she immersed herself in things popular among students—such as video games and manga—crafting a likeable persona based on them.

Filimøs deeply cares for her students, and even after reincarnation, she works tirelessly to keep them safe. This is evident in how she greatly lamented their precarious situation. She was especially distressed upon witnessing their potential deaths through her bonus skill, [Student Roster].

As revealed in her inner thoughts, Oka has admitted that she is not a particularly strong person and was unable to completely let go of her previous life to start anew. She clung to her former identity as a teacher and prioritized the safety of her students above all else.

Furthermore, due to the distressing effects of her unique skill, which allows her to foresee the potential deaths of her students, she took full responsibility for their well-being. Unconsciously, for these very reasons, she came to believe that only she knew what was best for them, regardless of their choices and free will. This mindset is evident in her decision to have the elves gather the reincarnated students and forcibly confine them in the Elf Village while they were still too young to resist. She justified her actions by convincing herself that she was in the right—that protecting them in confinement was better than leaving them to fend for themselves in the dangers of the new world.

Later, as seen in the cases of Sophia and Wrath, Oka demonstrated that she was either unable or unwilling to even attempt to understand their reasons for refusing her offer of “protection.” However, it should be noted that the elves influenced her, making it even more difficult for her to comprehend their rejection.

Her tendency to act based solely on what she believes is right—without fully understanding the situation—is also evident in the method she used to “help” Hugo regain his “humanity.” She assumed that stripping him of his skills and stats would have a positive effect on his mind, despite knowing his personality both before and after reincarnation. However, she was later baffled and surprised when her actions only worsened his issues.

Having been raised by the elves, Oka developed a degree of ingrained antagonism toward the Administrators due to their indoctrination since her reincarnation. However, because she already had a fully developed mind and harbored doubts about the elves, her own hostility was much weaker, and she questioned the truthfulness of their beliefs.

Nevertheless, her inability—or refusal—to understand Wrath and Sophia’s reasons for assisting the Administrators led her to view them with hostility. This was likely driven by an unconscious desire to validate her actions as just and to reaffirm that she was in the right while working with the elves.

After the battle at the Elf Village, during the conference between the reincarnates, Oka learned the truth about Potimas and the elves from Wakaba. Overwhelmed by the realization that all her efforts had been in vain, she broke down in tears and began hyperventilating.

Synopsis[]

Before the mysterious explosion, Okazaki Kanami was the bubbly and kind homeroom teacher at Heishi High School. She was well-versed in pop culture and other forms of media that were popular among her students.

Filimøs was reincarnated in the Elf Village as the daughter of Potimas Harrifenas. One of her first actions was learning Telepathy to communicate with her father and tell him everything. Potimas agreed to provide all the assistance she needed to find the students.

After several years, Filimøs traveled to the Kingdom of Analeit to meet three students—Shunsuke Yamada, Ooshima Kanata, and Shinohara Mirei—and offered them the chance to accompany her to the academy.

She is often absent from the academy while assisting the elves in their efforts to avert the approaching war[1] but returns at Leston's request after Shun becomes the Hero.[2]

Filimøs was reincarnated as an elf because a certain god thought it would be more entertaining.

Relationships[]

Administrators
Having been raised by the elves and unaware of the true state of the world, Filimøs believes that the Administrators who oversee the System are malevolent, god-like beings who view the people of the world merely as a source of power to siphon for themselves. However, it is evident that she does not fully believe this narrative, as her distrust toward the elves has been growing—especially after learning the truth from Wakaba.
Hugo Baint von Renxandt
Ms. Oka has shown deep care for Hugo, valuing him just as much as her other students, and has made efforts to help him control his arrogance. She has expressed regret over her inability to stop him from gradually spiraling out of control. However, despite her good intentions, it is evident that Oka never truly understood Hugo as a person. As a result, her attempts to help him only served to worsen his megalomania. Furthermore, her efforts to make him “regain” his humanity only led him to develop a deep grudge and intense hatred toward her. During the battle at the Elf Village, Oka steeled herself for what she saw as her duty as his teacher—to kill Hugo and end his tyranny. However, during their fight, she was both shocked and horrified by the lengths he went to in order to regain his strength after she had initially stripped him of his skills and stats. The most striking moment was his revelation of the Lust and Greed skills, particularly how he not only restored but even surpassed his original power through excessive use of the Greed skill.
Sophia Keren
In their previous lives, Okazaki tried to help Negishi when she refused to attend school out of fear of being bullied, but her efforts were in vain. Similarly, after reincarnating, Filimøs attempted to “rescue” Sophia when she was supposedly “kidnapped” by Ariel, only for Sophia to fail to recognize her and attack her. The two would not cross paths again until years later, during an investigation into the disappearance of several elves. Filimøs was shocked to discover that Sophia was the culprit and that she was apparently working for an Administrator. Following this, Filimøs largely gave up on Sophia, though her continued use of Sophia’s old name with the “-chan” suffix suggests she still feels some attachment to her. Despite their past animosity, after the conclusion of the main story, Filimøs eventually grew closer to Sophia, with the latter visiting her regularly—likely due to both having been reincarnated as long-lived races.
Wrath
She attempted multiple times to bring him to the Elf Village but ultimately failed, as Wrath was aware of the elves' true motives. Like Sophia, Filimøs was deeply troubled and confused by Wrath’s actions, largely due to her ignorance of the true state of the world. When she encountered him again in the Elf Village, she regarded him as an enemy.
Wakaba Hiiro
Wakaba was one of Ms. Oka's students in their first life. While Filimøs traveled the world in search of her former students, she seemingly made no effort to look for Wakaba’s reincarnation, as her Student Roster skill had already indicated that Wakaba was deceased.
As a result, during the climax of the Elf Village Battle, Ms. Oka was shocked to discover that Wakaba was, in fact, still alive, prompting her to immediately double-check using her skill.
Schlain “Shun” Zagan Analeit
Schlain is one of the reincarnations and a former student of Oka. Like all her students, Filimøs deeply cares for him and does her best to guide and support him. In turn, Schlain has shown great concern for her and generally gives her the benefit of the doubt despite her vague explanations and words.
Karnatia “Katia” Seri Anabald
Like all reincarnations, Filimøs cares for Karnatia and does her best to protect her, seeing it as her duty as their former teacher. In turn, Karnatia maintains a more or less amicable relationship with her and continues to refer to her by her former name, “Oka,” during their time at the academy. However, their interactions suggest that Karnatia does not fully trust Filimøs. Unlike Schlain, who gives her the benefit of the doubt, Karnatia harbors many suspicions about Oka and frequently questions her actions and intentions.
Elf Village Reincarnations
Upon reincarnating and using her unique skill to foresee the possible deaths of her former students, Oka immediately set out to "save" them. She attempted to do so by working with the elves to bring them under their protection in the Elf Village, successfully securing eleven of them. However, despite her good intentions, Oka may have ultimately caused more harm than good, as the elves used various illegal and often murderous methods to obtain the reincarnations. It was later implied—and eventually confirmed—that the elves personally killed some reincarnations' new families to abduct them, pressured parents into selling their children as slaves, or outright kidnapped them as infants. To further conceal their actions, the elves even created a global child trafficking network, responsible for large-scale operations that helped disguise their true objective of acquiring reincarnated students. Unbeknownst to Oka, she may have even indirectly caused the deaths of some students, as the elves killed or attempted to kill a few of them due to their unique skills and abilities being seen as a threat to Potimas. Those who were successfully "saved" were taken to the Elf Village, where they were raised in complete isolation and forced to live under the constant surveillance and strict rules of the elves. Many of them came to resent—and even outright hate—Oka for the prison-like conditions they were subjected to. Many reincarnations openly express their dissatisfaction with their situation, showing their distrust and anger toward Oka whenever she visits the village. Oka herself has admitted to feeling guilty for forcing them into this life, yet she justifies her actions by convincing herself that keeping them confined is preferable to the possibility of them dying while trying to survive in the new world.
Sachi Kudo
Due to the suspicious circumstances surrounding the reincarnations brought to the Elf Village, Sachi personally disliked Oka despite her good intentions and viewed herself and the other reincarnations as victims of kidnapping. In their interactions, Sachi openly expresses her hostility and resentment toward Oka, who, in turn, does not attempt to defend herself—acknowledging that Sachi is, in a way, justified in suspecting the elves of wrongdoing.
Elves
Filimøs is respected by the other elves solely because she is the direct offspring of their patriarch. In turn, she is grateful to them for helping her secure her students. However, it is evident that she does not fully trust the elves due to their arrogant disposition toward other races. She also remains unaware that they have killed those they deemed too dangerous. During operations, the elves see Filimøs as a leader and generally follow her commands when assigned to her in teams. She was also shown leading the defending forces during the Empire’s invasion of the Elf Village. However, it is clear that they only obey her due to her status as Potimas’s daughter and nothing more. Many elves regard her with hostility because of her differing views and merely tolerate her because of her connection to Potimas. Much like Potimas himself, the elves who serve him secretly look down on Oka, mocking how easily she can be manipulated through her concern for the reincarnations. After learning the truth about the elves, she deeply regretted siding with them.
Potimas Harrifenas
As his daughter, Oka knows Potimas well enough to understand that he would never save the reincarnations out of kindness. She acknowledges that they never truly had a familial relationship and merely used each other.[3] However, she remains unaware of the true depths of his megalomania and fails to realize that he has been manipulating her. After learning the truth about him, she begins to regret being reincarnated as his daughter.

Powers & Abilities[]

As an elf, Filimøs possesses a high aptitude for magic. Drawing from her knowledge of fantasy novels in her past life and her mature mentality as an adult, she demonstrates exceptional skill and adaptability in magic. Furthermore, her experience working alongside the elves in infiltration has made her proficient in stealth and combat, enabling her to hold her own against stronger opponents.

Equipment[]

  • Unnamed Bow: Filimøs' primary weapon. It allows her to fire arrows enhanced with wind magic, making them powerful enough to easily pierce through a person’s head.

Titles & Skills[]

  • Student Roster: Filimøs' unique skill as a reincarnation. It provides her with basic information about each of her reincarnated students, including their place of birth, health status, and predicted time of death. However, the skill comes with a restriction preventing her from discussing it with her students.[4] Furthermore, it cannot track students who are not part of the System; in such cases, they are automatically registered as "deceased."
  • Telepathy: Enables her to communicate directly with others through their minds.
  • Ruler Skill: Filimøs possesses a yet-to-be-revealed Ruler Skill. As part of being a Ruler, she has the ability to freely interact with the System, allowing her to perform actions such as removing someone else's skills.[5] This skill also grants her the ability to search for an entity based on skill ownership, enabling her to locate individuals through their unique skill composition. However, it comes with significant drawbacks. After stripping someone of their skills and stats, Oka loses some of her own EXP and becomes so weakened that she enters a coma-like state until she recovers. It is later revealed that her Ruler Skill is Charity.
  • Wind Magic: Allows her to summon and manipulate wind.
    • Dragon Wind:

Other Abilities[]

  • Elf Physiology: As an elf, she ages more slowly and has a longer lifespan than most humanoid beings. However, this also means she remains a child for a longer period, which can be a disadvantage.

Trivia[]

  • According to D, Filimøs has the smallest chest in the series. Ariel and Sue are second and third place respectively.
  • According to D, she tampered with Filimøs's Student Roster information somewhat.
  • Due to Potimas using his genetics to create human-animal hybrids, Filimøs is technically related to some of the most powerful beings in the world, including individuals who became the progenitors of entire races.
    • She is, for example, connected to the Taratect species through her half-sister, which is ironic since she herself is fond of spiders.
