History Characters / WelcomeToDemonSchoolIrumaKunAntagonists

* BigSisterInstinct: Regardless of [[AmbiguouslyEvil the ambiguity of why she's a Finger]], ever since she met and spent the day with Iruma, she grew to care for and cherish him like he's genuinely her little brother, and she utterly refuses to let any harm come to him, even if that means defying Wett's orders.

* MirrorCharacter: To Iruma. Both have been abused by their biological parents, were shunned and eventually abandoned by them, are incredibly weak magically with their only natural strength being defensive actions, Kiriwo using barriers while Iruma dodges things, and have magical tools which allow them greater access to magical abilities thanks to the magic of an adoptive figure in their lives, Iruma possessing the Ring of Gluttony imbued by his grandfather's power, and after his escape from Walter Park Baal had a ring-shaped tag made for Kiriwo and imbued with his own power. But whereas Iruma wants to make the Demon World a better, happier place like Bablys and is a HopeBringer to many close to him, Kiriwo is a HopeCrusher who seeks to destroy the stability of the Demon World and make it a chaotic nightmare.

* VillainousRescue: After Iruma launches the empowered firework shell into the sky, shattering the final barrier around the school and saving the students from the immediate explosion, Iruma passes out from exhaustion and would have fallen off the top of the three story school building he was on down onto the ground, but Kririwo saves him with a barrier strong enough to hold both Iruma and then Kiriwo himself as he joins the now sleeping Iruma on the barrier and has a minor breakdown.

* BloodKnight: Turns out that having someone who can defend against him at all is enough to send him into a murderous frenzy. [[spoiler:During the Heartbreaker exam, he quickly blows his cover as a teacher by attempting to kill Sabro and his underclassmen, consciously realizing that he had gone too far but didn't want to stop, all because they didn't immediately get taken out. Sabro is forced to activate his wicked phase in order to avoid a fatal blow.]]

* TheCorrupter: He hopes to find impressionable students he can convert to join their goal to returning the world to its more chaotic times. [[spoiler:He is giddy when Sabro unleashes his bloodline power, turning the boy into a sadistic combatant by means of a pill, and plans to give him another one to further his descent into darkness. Only Balam's intervention stops Atori]].

* FauxAffablyEvil: Altori acts like a CoolTeacher for the Misfit class but he's also quite excited by Baal's order to murder a few of them if they get in the way of his mission.

* VillainRespect: After he sees through Soi's powerful magic and pops both of the balloons, he gives genuine praise to Soi for doing something so advanced at a young age, noting it was just bad luck Atori was nearby.

* FashionableAsymmetry: He wears a long coat cut in half on his left side after he escapes from prison.

A demon that Baal took in after noticing that the former had gone through "Return to Origin." AKA, Kiriwo became an evil demon that returned to his chaotic demon roots. First introduced as a senior Babyls student leading the magical tools research division, Kiriwo befriends Iruma after the latter took an interest in joining said division. However, to further Baal's goal of spreading chaos, Kiriwo had been working behind-the-scenes at Babyls to set up a machine that will blow up the school during the Battler Party. In the end, Iruma manages to put a stop to the plan, which resulted in Kiriwo's arrest, but this also results in Kiriwo self-proclaiming himself as Iruma's arch-nemesis. With the help of the Six Fingers breaking him out of prison, Kiriwo returns to Baal's side, and awaits the day that he finally reunites with Iruma.

* ArcVillain: He serves as the main villain of the Harvest Festival arc having infiltrated Babyls in order to gather information on the first-year students for his boss, Baal. During his information gathering, Ocho manipulates the Babyls student, Orobas, into believing that he has to eliminate all the misfit students from the festival to win. Ocho then leaves following the festival once the teachers start to catch on that he's there, but he escapes with the information he discovered.

[[folder:The Six Fingers]]
!The Six Fingers

A well-known terrorist organization that's secretly working under Baal. They're responsible for the partial destruction of Walter Park, as well as Kiriwo's escape from Wlavoras Prison.

!!In General

He is introduced as Romiere Ronove's assistant and handler while Romiere goes about Walter Park. He is the leader of the terrorist group, The Six Fingers.

!!Third Finger - Hyudarin
!!!'''Voiced by:''' Volcano Ota (Japanese)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/hyudarin_anime.png]]

* EvilOldFolks: A member of a terrorist group and he is visibly older than the other members.
* FashionDesigner: As part of his cover in Walter Park, he works in a clothing boutique and helps quickly mend and alter clothing for patrons.
* PintSizedPowerhouse: He's so tiny he can fit on a normal-sized person's shoulder, but he's also so strong that he can utterly crush the hands of a massive-by-normal-standards demon.

!!Fourth Finger - Miki
!!!'''Voiced by:''' Creator/ChitoseMorinaga (Japanese), [[WebVideo/LilyPichu Lily Ki]] (credited as LilyPichu) (English)
[[quoteright:230:https://static.tvtropes.org/pmwiki/pub/images/b157337_ouomj3cyqidj.png]]

!!Fifth Finger - Atori
!!!'''Voiced by:''' Tatsumaru Tachibana (Japanese), Creator/KeithSilverstein (English)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/atori_anime.png]]
----
* TheBusCameBack: He returns in Chapter 220 alongside Sheeda, having infiltrated Babyls pretending to be a new teacher.
* ExactWords: He gets around Balam's LivingLieDetector skill with this. Too bad Balam is well aware of this loophole and noticed he was hiding something via body reactions.
* FacialMarkings: He has six prominent spike markings on his face, three under each eye. He still has them outside his "uniform" when acting as a new Babyls teacher, so they're apparently natural.
* FauxAffablyEvil: Altori acts like a CoolTeacher for the misfit class but he's also quite excited by Baal's order to murder a few of them if they get in the way of his mission.
* LockedOutOfTheLoop: He and Sheeda don't seem to be aware that Iruma is actually human as they're confused as to why Baal would want Iruma brought to him if he becomes suspicious of them. Presumably he didn't tell them so they wouldn't be tempted to eat him, which would be a wise move considering Atori's personality.
* NoodleIncident: When asked how he was able to spot Purson's team (who are all invisible) almost instantly, he simply replies that he "knows someone who can use that magic."
* VillainRespect: After he sees through Soi's powerful magic and pops both of the balloons, he gives genuine praise to Soi for doing something so advanced at a young age, noting it was just bad luck Atori was nearby.

!!Sixth Finger - Maemaro
!!!'''Voiced by:''' Motoki Sakuma (Japanese)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/maemaro_anime.png]]
----
* DemBones: He stands out very noticeably compared to every other demon, all of whom already have such a massive variety in appearance, because he's a living skeleton (he can even have his individual bones separated harmlessly, simply needing to reassemble them afterwards). It's a bit ambiguous if he's even a demon at all, or instead a genuine undead being.

[[folder:The Second Finger]]
!!Sheeda - Second Finger
!!!'''Voiced by:''' Azuki Shibuya (Japanese), Heather Gonzalez (English)
!!!'''Debut:''' Chapter 72 (Manga), Episode 37 (Anime)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shiidaanime1st.png]]

While masquerading as a Walter Park staff member, she rescues Iruma after he found himself lost in a shady street, eventually escorting him back to his classmates and guardian. She later comes to work at Babyls as a teacher on a covert mission from Baal.
----

[[folder:Ocho]]
!!Ocho
!!!'''Debut:''' Chapter 122 (Manga)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/image_1_870.jpg]]
A subordinate of Baal, and a member of ''The Cult Of Numeral 2''. He's tasked with gathering information on the first-year students of Babyls Demon School during the Harvest Festival, which he does so by pretending to be Orobas's ImaginaryFriend.

[[/folder]]

* VillainousRescue: After Iruma launches the empowered firework shell into the sky, shattering the final barrier around the school and saving the students from the immediate explosion, Iruma passes out from exhaustion and would have fallen off the top of the school building he was on down onto the ground, but Kririwo saved him with a barrier strong enough to hold both Iruma and then Kiriwo himself as he joined the now sleeping Iruma on the barrier and had a minor breakdown.

* YouAreBetterThanYouThinkYouAre: Iruma seems to think so anyway. Even after hearing himself that Kiriwo's a [[TheSociopath sociopath]], Iruma still believes Kiriwo's ambition of creating a society where rank doesn't matter is genuinely noble, even if Kiriwo is misguided in his methods. It's implied there ''is'' a bit more depth to Kiriwo's character, given that he unnecessarily saved Iruma from falling to his death, even though Iruma had just foiled his plans.

* ArcVillain: The group as a whole for the Walter Park arc where they release 3 massive demonic beasts upon Walter Park to cause chaos, which it also provides a distraction for them to break out Kiriwo from the Wlavoras Prison beneath said park.

* ArcVillain: He acts as the main villain of the School Festival Arc, trying to blow up the school in order to bring about chaos to the entirety of the netherworld's society.

!!Second Finger - Sheeda
!!!'''Voiced by:''' Azuki Shibuya (Japanese), Heather Gonzalez (English)
!!!'''Debut:''' Chapter 72 (Manga), Episode 37 (Anime)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shiidaanime1st.png]]
While masquerading as a Walter Park staff member, she rescues Iruma after he found himself lost in a shady street, eventually escorting him back to his classmates and guardian. She later comes to work at Babyls as a teacher on a covert mission from Baal.

* AmbiguouslyEvil: It's heavily uncertain why she's part of the Six Fingers, as while she's counted among their number and acts as a look-out to make sure everything is set up for their plan to work, she's the only member who never directly engages in chaotic terrorism like the other five, along with showing hints of uncertainty about being in the group. She also never directly confirms or denies sharing the groups overall goal of returning demonkind to its "origins", so why she joined Wett is unclear.
* BareYourMidriff: As a result of only wearing a sports bra on her torso in her Walter Park outfit, her stomach area is completely exposed.
* BigSisterInstinct: Regardless of [[AmbiguouslyEvil the ambiguity of why she's a Finger]], ever since she met and spent the day with Iruma, she grew to care for and cherish him like he's genuinely her little brother, and she utterly refuses to let any harm come to him, even if that means defying Wett's orders.
* TheBusCameBack: She returns in chapter 220 due to infiltrating Babylis under the guise of a new teacher alongside Atori.
* BoyishShortHair: While spiky, her hair doesn't go past her neck, and she has a rather tomboyish demeanor.
* ClothingDamage: Completely unintentional on Iruma's part but when he tried to use his arrows to merely pin her to a wall by shooting her clothing, Sheeda unknowingly tears her own outfit to pieces freeing herself. Iruma, now a blushing mess, has to point out her current state of being. This leads her to calling Iruma a pervert.
* CoolBigSis: She pretends to be Iruma's sister to save him from some shady people. She then proceeds to spend some time acting like a doting older sister to him.
* FaceOfAThug: She's got a rather stern face, as well as an intense glare, which causes her to scare away animals when she tries to touch them, but based on the short amount of time Iruma was with her, she doesn't seem to be a bad person. It goes double following the reveal of her being part of the terrorist group the Six Fingers, as all the most villainous members either have the FaceOfAnAngelMindOfADemon or [[TheyLookLikeEveryoneElse look like an average demon]], while she's second only to [[DemBones Maemaro]] in scary looks yet is the TokenGoodTeammate.
* ForcedIntoEvil: It is heavily implied that she is not in this group willingly.
* FriendshipTrinket: The photo of her and Iruma, with her being removed by Wett's magic, is something she still keeps on her person and looks at when alone. She swears to it that she won't let anyone hurt Iruma.
* FunbagAirbag: In the process of saving Iruma from some shady back alley folk, she uses her (small, but not flat) chest to gently cushion his fall after he was dragged off his feet. Iruma found them quite soft.
* JustToyingWithThem: What Chima feels Sheeda did with her Heartbreaker team, easily catching Chima from behind before jumping back and requesting a do-over, very clearly being able to pop her balloon before they could even react. Chima is understandably sweating buckets afterwards, noting the difference in skill between them.
* KickChick: As Atori notes, her "favorite" method for solving arguments and other disagreements she doesn't care to deal with is to use her legs to kick the opposing person into conceding, and those legs are strong and powerful enough to make even decently powerful magic a barely inconvenient stop-gap to her hitting what she's aiming for.
* LockedOutOfTheLoop: She and Atori don't seem to be aware that Iruma is actually human as they're confused as to why Baal would want Iruma brought to him if he becomes suspicious. Presumably he didn't tell them so they wouldn't be tempted to eat him.
* LuminescentBlush: She gives off a very prominent blush after her clothing gets torn by Iruma during the Heartbreaker competition and exposed plenty of skin to the boy, calling him a pervert for it despite Iruma's protests about it being an accident.
* MsFanservice: Sheeda's a beautiful woman with a decently curvy body that gets shown off well by her {{Stripperific}} Walter Park outfit, and even after putting on a conservative teacher outfit for Babyls, the story sees fit to have her "fight" against Iruma include some ClothingDamage just to have an excuse for showing off her legs and a bit of her chest again.
* PreAsskickingOneLiner: "I'll kick you."
* ShesGotLegs: Special attention is given to Sheeda's legs after she demonstrates her proficiency in kicking.
* SpellMyNameWithAnS: Her name has been translated as Sheeda, Shiida, and even Cedar.
* StealthHiBye: After she gets Iruma back to his group, when Iruma turns back to introduce her to his classmates she'd already vanished back off to work.
* TheStoic: For most of the time she is with Iruma, she held a rather unemotive face, though after spending some time with Iruma having fun, [[NotSoStoic she does]] [[WhenSheSmiles end up smiling.]]
* {{Stripperific}}: Her Walter Park outfit consists of little more than really short shorts, a sports bra, a cape, and nothing else.
* StrongerThanTheyLook: She has a rather lithe build, but despite that, she has a strong enough grip to easily crush another person's hand in hers, and her legs are strong enough to destroy walls with kicks or shatter the ground with slightly forceful stomps.
* TheReasonYouSuckSpeech: As a participating teacher in the Heartbreaker competition at Babyls, she takes the duty to assess and help her students grow seriously. When she faces Iruma and studies his archery skills, she realizes he isn't aiming to kill her but shoot her clothing to pin her down so he can escape with her being minimally injured. She calls him out on this tactic saying only the extremely strong or too cowardly use it. He is the latter and should become comfortable with actually hurting people in a combat situation. She does this again when Chima tries to fight her, scolding her for choosing to fight a teacher when it was ''obvious'' a first year wouldn't be able to do anything.
* TokenGoodTeammate: Her exact alignment [[AmbiguouslyEvil is very unclear]], with implications that she might be ForcedIntoEvil, but what has been shown about her makes it very certain that she has the highest morals out of not just the Six Fingers but the whole villain faction, refusing to personally engage in any form of terrorism and being very protective of Iruma [[BecauseYouWereNiceToMe simply because he was nice and compassionate to her]].
* TomboyWithAGirlyStreak: She's rather stern and serious normally, and fully up for fighting if necessary, but she likes animals despite scaring them, and enjoyed spending time having fun with Iruma, even if she just met him. She also shows an interest in gardening.
* VerbalTic: When she speaks, she has a habit of pausing in the middle of her sentences.
* WhenSheSmiles: While her normal expression is an emotionless glare, when Iruma thanks her for helping and spending time with him, she flashes him a gentle smile. She does it again when looking at a photo they took together before getting back to work.
