Babyls School Newsletter (Timeline of Major Events): @babyls-school-newsletter
Purson Soi is a character from Mairimashits Iruma-kun or Welcome to Demon School Iruma-kun, often shortened to Mairuma or WTDSIK. In both official and fanmade translations, Soi is shown to use he/him pronouns, but Mod is fine leaving the pronouns up to interpretation for this rp blog’s interpretation. Soi is approximately 15 years old (unsure if that translated with Deviler's added time per year) and a second-year of the Misifts Class at Babyls. He is currently ranked Daleth as a result of the Music Festival. He was present but received little to no screen/pagetime in arcs preceding the Music Festival arc. He can be a little shy, but he can be a chatterbox once he gets comfortable. He can also be a little sarcastic at times.

This is my first animatic genuinely ever. I honestly thought I was gonna quit and just keep it as basic shadows no colors because I hated the flat colors… but ph my gosh I am so so so happy with how it turned out!!! 10 frames, last frame is my favorite so I’ll add it to this post as a single picture too.
I am absolutely in love with how my dearest Madeleine looks here… I hope everyone else will love this too! She’s such a cutie patootie to me <3 <3 <3
do you ever think your brother actually went missing instead?
Well that's pretty much what he did... left, disappeared. Are you implying he was kidnapped? I don't see that being possible, I'd be surprised anybody figured out where he was at any point in time.

Hi Purson Soi~! I got Murmur-sensei's permission to make an essay on the effect high achieving older siblings have on a younger sibling. I'm sending this to everyone I know on here that has an older sibling.
Please respond as you see fit:
Do you believe your older sibling is high achieving?
→ In what ways are they high achieving?
How does your family act towards them versus towards you?
How does your sibling act towards you? (for example: do they help you or do they hold it over you? kind big sibling or evil uncaring big sibling)
Have demons that know your sibling behaved differently towards you than they would have if they didn't? If so positively or negatively?
How would you say your relationship has personally affected you?
→ do you believe you would've been better off without your sibling?
→ have you learned anything from your older siblings (if yes what)
→ would you need to do more without your sibling?
Finally, can you describe your relationship in 1 sentence?
Thank you for participating~! It's highly appreciated !
- @date-anon
(this is just for fun but i might actually write an essay from date-anon's view and stuff if i get bored enough or something at some point lol)
Hello, Date-Anon, I’m sorry for taking so long to answer this survey.
… I do believe that my brother would be considered high achieving. I would say that he's high achieving in that he had great skill and honed his detection warding to near perfection. However, he never won any awards or had outstanding rankings or anything like that, though by our family's standards, that would indeed be considered high achieving…
My brother disappeared completely when I was younger, so all of his responsibilities and all the expectations my parents had for him fell to me. My parents treat me well, but sometimes I worry that a part of them, particularly my father, would have preferred my brother be the heir instead…
He disappeared while I was still very young, so I don’t remember much of him, but I think he was a good brother, save for the deadbeat part. I’m grateful for what he taught me, it’s what helped me during the Heartbreaker, and I’m glad to have the opportunity to be head of the family in the future, but I’m also a little frustrated because it’s originally his responsibility, and that’s partially the reason I had so much trouble participating in the Music Festival and was unable to connect with everyone prior to that.
I don’t think many people know both me and my older brother…
Sometimes I wonder where he went or what he’s doing, but he doesn’t really affect my day to day life much. Maybe the fact that my parents’ responsibilities were aimed at him while I was still young allowed me to be a little more free? If that’s the case, I suppose I’d have to thank him because I’m rather happy where I am right now.
He taught me how to use my bloodline ability, and that was also the memory that allowed me to figure out how to mask multiple demons at once.
He’s pretty much gone now, as I’ve already stated multiple times, so I’m not quite sure, but I’d probably not be as involved with school activities so much as training to be head of the clan if he never existed, since I wouldn’t have had so much freedom as a child.
I’m not sure there even is a relationship to describe at this point in time, unfortunately.
"The Boku Alliance is at each other's throats after a poll failed to decide who is the oldest and youngest brothers of the group! Will this dilemma ever be sorted out? Stay tuned to find out!"
"When Sullivan-sama first spoke to me about devilblr, I thought I'd be far too busy to engage with it myself. Then, however, I saw how much fun you all seem to be having on here. Well, I'd hate to be left out~"
"For those of you who don't know me: Hello! My name is Aria, I'm a teacher at Babyls Demon School. I also manage the student dorms and assist Sullivan-sama as a security devil and assistant at work. For matters concerning Sullivan-sama's other activities, please consult my elder sibling. (He's only my problem when he's at the office~)"
"For my darling students: Hi hi~! I'm just as happy to chat with you here as I am at school, so please stop by!"

For general info about mod and rules, etc, please see the pinned post on my other blog @babyls-gargoyle
Hi there! This is an rp blog for my oc from Mairimashita! Iruma-kun/Welcome to Demon School Iruma-kun. I know oc's aren't everyone's cup of tea, so rest assured I will NOT pressure anyone to interact if they don't want to. This includes characters this oc has a connection to in her lore. I tend to "anchor" oc's to the narrative by giving them relationships to canon characters. I know some people consider that "cringe" or whatever but it just makes more sense to me that way. (Mairuma also does this a lot, have you noticed? We're often introduced to a new character by establishing them as a relative of someone we already know. Chima? Kerori's sister. Yabashi? Related to Marbas-sensei. Marnie? Vine's sister.)
Any reactions and other images of Aria used on this blog were edited from manga screenshots by me using my very rusty editing skills and a horribly old trackpad laptop. I know some of them look a bit scuffed but I am NOT a visual artist-
About Aria✨️
Upon arrival at Babyls Demon School, every new student is greeted first by the Student Council. The next demon they meet, however, tends to be Aria. With her easy-going nature and friendly approach, she can usually be found all over the school and is always happy to give directions, helpful advice, or a merciless take-down should she find anyone causing trouble. Always with a smile, of course~!✨️
Bio
Name:
Aria. Also called Aria-sensei by students, Aria-chan by Sullivan, family and coworkers. Sometimes called 'Babyls itself' in the same way Kalego and Balam are called 'guard dog' and 'gargoyle' due to her bloodline ability.
Rank:
Khet (8)
Background:
Aria was taken in by Sullivan at an early age, alongside her older sibling Opera. She followed Opera's lead and started trying to repay Sullivan by taking on chores and looking after the house. (She's the maid to Opera's butler, basically.)
Sullivan also provided her an education at Babyls, where she was put into the same class as Naberius Kalego and Balam Shichiro. In a further effort to repay Sullivan she joined her sibling and classmates in the Top Dog Battler, tearing through the school on a troublemaking spree to rid it of other troublemakers.
At some point after graduation, she joined the staff at Babyls along with Balam and Kalego, as well as joining Opera as Sullivan's Security Devils. (Opera looks after the mansion, Aria looks after the school.)
Occupation:
Aria acts as Sullivan's security devil while he's at work, essentially functioning as his personal assistant - managing his schedule, keeping him updated on events at the school, and working with Opera to ensure he does his paperwork.
In addition to this, she also teaches Siege Tactics, an elective like Raim's seduction class. Not to be confused with Ipos' Tactics class or mistaken for a class on Warfare, Siege Tactics teaches how to defend, maintain and run a household. In other words, it's cooking and home economics class.
She also takes an interest in managing the student dorms and looking after the students staying there.
Bloodline Ability:
Home Territory. This ability allows the user to designate an area or building (in Aria's case Babyls) as their own. This gives them rough knowledge of anything going on within the perimeter (limited, especially since the school grounds are so large) and the ability to reshape the terrain as they see fit. (She can move corridors around, drop walls on threats or make the ground/floor swallow them, for instance. It works a bit like Agares' "My Area", except while he can do it anywhere Aria has to bind herself to a specific place and can only use her powers there. The giant forest that popped up overnight behind the school for the harvest festival was a joint effort between her, Balam and Suzy.)
While this ability makes her a powerful defensive weapon and asset to the security team, it does come with some drawbacks. In a manner of speaking, Aria is the castle. This means that if the school is too significantly damaged, she will become physically injured as a result. (Wrecking a few corridors like during the Heartbreaker is fine, but anything beyond that puts her at risk. She's also how the faculty could just put all that damage back together so quickly.) Magic effects can also rebound on her if cast on her territory, for instance Kiriwo blocking off the castle with barriers caused her to experience full-body paralysis.
Her powers are also somewhat affected by the people in her territory. Basically the stronger their sense of camaraderie, cooperation, and love for the school is the more of a boost she gets. Because of this, her favorite student outside the misfits class is Ameri.
Your bloodline ability is detection warding, correct?
What are the limitations of it? Is it capable of masking noise, mana, ect… or only your visibility?
It seems very useful.
-👁️
Yes, that is indeed my bloodline ability. I, personally, am only able to mask appearance (of multiple people) so far, but i aspire to better conceal my presence. I'd say that the limits depend on personal ability, but there are probably still hard limits. My brother could probably better answer your question... I'd say that based on how completely he's disappeared, it's likely that noise and mana are able to be masked to some extent, but that would likely require immense concentration and skill... theres also probably a limit to how many people i can conceal, but i havent tried maxing it out yet... I hope that answered your question, eye-anon.

Hello there people of Devilblr! We're back again with yet another article detailing the mysterious events that had occurred a few days prior. This incident involved the infamous Misfit Class as usual, yet it seems this time they were the targets instead of the instigators.
It all started when the honor student Iruma had received an ask (Tue, Jun 09, 2026, 04:54:16 PM UTC) informing him of the fact that random malicious notes were being found in lockers and on desks belonging to students. Apparently, a third year had already informed the teachers. Following this, the first recorded occurrence of a threatening note being found by one of the Misfits was none other than Iruma himself (Tue, Jun 09, 2026, 05:10:13 PM UTC), who had swiftly informed their Homeroom Teacher Naberius Kalego, who had in turn also contacted Security Devil Opera for security measures. No one other than the Misfits and the teachers can freely access the Royal One, so a breach of security was suspected.
Meanwhile, the next two victims were Valac Clara and Agares Picero. While Agares had brushed it off easily and similarly informed his homeroom teacher, Clara seemed rather shaken. Though later on it seemed like a talk with Iruma had lifted her spirits. Asmodeus Alice received his note shortly later, though he seemed fairly composed compared to the rest. The next victims were the Misfits Andro M. Jazz—who didn't seem bothered about it in the slightest—,Purson Soi, Shax Lied and Crocell Kerori. The only Misfits to not receive a targeted, personal note seem to be Allocer Schneider, Sabnock Sabro and Gaap Goemon. Ix Elizabetta and Caim Kamui, the only two Misfits to not be present on Devilblr at the time, did not receive such a note.
A conversation between Former Babyls Student Kiriwo Amy and Iruma had revealed that the threatening notes were being spread by three unknown demons under the supposed leadership of the Six Fingers, who had apparently gone rogue. Several Babyls Faculty members like Naberius Kalego, Balam Shichiro, Bars Robin and Stolas Suzy who were present on the site had also received similar notes. Babyls student Date-anon had received a similar malicious note as well. However, Security Devil Opera had received no such note.
Meanwhile, other nameless criminals under the infamous terrorist group had launched an attack on Demon Border Control. Border Control Commander Naberius Narnia had joined the hunt for these criminals. Interestingly, their leader Amy Kiriwo himself had offered to help apprehend them because they were supposedly creating trouble for him as well, calling the Former Thirteen Crown Amduscias Poro for help because the demons were apparently ‘trashing the throne room’.
As of now, due to a series of events we'll be covering in a future article, all the mysterious culprits have been apprehended by Amy Kiriwo. But the Six Fingers still live on, and this could only be the start of many attacks to come in the future. But don't worry, we at the Babyls School Newsletter Battler will always be there to bring the truth to light!
It's not me, and I'm not sure how anyone knew abt it, maybe another misfit? Though you were rather bold during it... I don't think it's anything worth hiding though, I think everyone knows about Iruma's army by now. Still, you traitor, getting a girl on your lap.
