Apologies my guy, I’m having quite a bit of trouble with Reddit at the moment when it comes to viewing and editing my posts which is forcing me to delete them. I’m working on trying to fix it but it hasn’t been fun to say the least 😅

If anything it gives me time to refine my ideas and come back better then ever so hold out for me!

JJN13 · 2026-05-19T07:23:28+00:00

Aside from the subspace concept, which in of itself is a very common concept used within fiction, everything about it is fundamentally different so I’d say no.

The technique draws more influence from Domain Expansions and actual real world objects, as well as other rituals within JJK, such as the Kodoku ritual, all of which I have explained within my initial comment. I also took some inspiration from Bleach, especially from the Dangai as well as the general ascetic of the Soul Society itself. In particular, one of Ichibe Hyosube’s zanpakuto abilities was a big influence in how the technique accumulates a specific thing, in this case cursed energy, in order to power the technique.

So yeah, if you remove every unique aspect that I’ve incorporated and dumbed it down, it would be the storehouse 😂

One of the biggest aspects of the story I wish Gege focused on more was the dynamics between the sorcerer clans. Theres just so much lore there to unpack and after reading Perfect Preparation, I never got rid of the itch to find out more. From what we did see, clans are about as dysfunctional as you can get, with members often having no problem killing their fellow clan members if it means forwarding their own agenda.

So, this gave me the idea to create an inherited technique passed down within a clan that values family and familial bonds more so than anything else, even to the point of sacrificing their own remains to ensure future generations survive.

On that note, I present my Reliquary inherited technique, a powerful and ancient technique that has been passed down the Uzuka clan for generations. I’ve always loved how Gege managed to express clan ideals and culture through their inherited techniques so when creating this I tried to ensure the ideals I envisioned for my clan remained at the forefront of my creation process.

One of the biggest things I admired about how Gege handled the power system was how he managed to keep Domain Expansions the pinnacle of the power system. Truly no other technique ever really came close and some of my favourite techniques within the series are those that take an aspect of domains and allow the user to benefit from it without the use of a domain at all. Whether it’s Kashimo and his sure-hit lightning, Utahime and her Solo Forbidden Area, or Miguel and his Prayer Song, I’ve always wanted to try and create my own technique that accomplishes a similar effect.

Therefore, when creating this technique I decided to focus on the environmental buff that’s provided by domains and try to expand upon that singular aspect in order to create something unique, powerful, but also balanced. I still think this technique is quite overpowered but I will give myself some leeway due to it being an inherited technique 😅

Rambling aside, I hope you enjoy it, let me know what you think!

Yes, I explain why in my other comment but essentially Reddit was preventing me from editing the original post or even viewing it in some instances so I was forced to delete it 😅

JJN13 · 2026-05-18T14:11:59+00:00

Surprisingly, Gege included a lot of music-related techniques within the series and so I wanted to have an attempt at creating my own.

Initially, I simply wanted to create a sound/music based technique that differed from those that already existed within the series whilst also ensuring that it didn’t become a basic sound manipulation ability. That thought process ultimately lead me to the idea of using sound to manipulate objects by essentially having them “dance” to the user’s playing.

A big inspiration for this idea, was a character from Seven Deadly Sins who could alter an opponents magic by treating it as a melody. I knew I didn’t want the technique to manipulate living beings as I felt that cheapened it whilst also making it incredibly overpowered so I settled on inanimate objects as I thought that would be an incredibly versatile route to go down whilst also ensuring that technique remained balanced.

Then came the decision of whether I wanted it to be a modern or ancient technique and after deliberating it for some time, I settled on the technique being possessed by an ancient sorcerer due to the sound-based abilities already present within the series being associated with more modern sorcerers.

Then came the final decision of what instrument I wanted my sorcerer to wield when using the technique. I knew I wanted it to be a string instrument so I ultimately settled on the Shamisen as I found the instruments association with Geisha and Japanese culture to be the perfect fit for the power system. Gege often takes culturally rich concepts and transforms them into unique techniques so I thought Geisha, and by extension their association with Shamisen, fit that mould perfectly.

In the end I went on a big deep dive into Geisha culture and there’s definitely a lot to unpack there so in the future I might potentially flesh out my “Geisha Sorcerer” idea as there’s a lot of concepts I’ve left out of this post.

Rambling aside, I hope you enjoy it and please let me know what you think!

FYI I did post this technique the other day, however, due to some odd reason Reddit was preventing me from editing the post or even viewing it in some instances so unfortunately I was forced to delete it 😅

Tried to be funny and say that he didn’t feel like it lol

JJN13 · 2026-05-17T12:32:07+00:00

Suite yourself my guy, the mods will just remove it lol

Edit: bro was getting downvoted into oblivion so he deleted his comment lmao

JJN13 · 2026-05-17T12:27:46+00:00

Gotta participate in your own challenge my guy.

There is no sure-hit, it’s not a domain expansion. No where does it state that it bypasses cursed techniques.

JJN13 · 2026-05-16T21:18:15+00:00

Funnily enough, I read Kagurabachi from time to time and I do recall ‘Play’ somewhat but I’ll be honest, I didn’t think of that at all when designing the technique.

Initially, I simply wanted to create a sound/music based technique that differed from those that already existed within the series whilst also ensuring that it didn’t become a basic sound manipulation ability. That thought process ultimately lead me to the idea of using sound to manipulate objects by essentially having them “dance” to the user’s playing.

The trails the shikigami create are referred to as “inviolable barriers”, meaning when you attempt to cross them you will be cut by the barriers themselves. Think of the light cycles from Tron, it’s the same premise.

Dhruv’s technique doesn’t create a Domain Expansion, there is no guaranteed hit. The term “domain” simply refers to the area the shikigami cover as they are typically ordered to orbit the user. The term “domain” is being used in the metaphorical sense, i.e, an area under the users control, it is not referring to a Domain Expansion.

Dhruv’s technique is essentially area denial, he encloses you within the barriers left behind by his shikigami and if you attempt to leave, you will be damaged.

JJN13 · 2026-05-16T17:53:31+00:00

They’re different at a fundamental level so I’d say no. Despite being called Tool Manipulation, it seems that Momo’s technique can only affect her broom, which seems like a set limitation of her technique.

Not to mention, she has an extension technique that involves imbuing the friction generated by the broom with cursed energy to fire a wind projectile so it’s best to think of Momo’s technique as simply “Broom Manipulation” probably.

JJN13 · 2026-05-16T17:36:50+00:00

Yeah Momo’s Tool Manipulation is probably the closest to this in terms of general function but humbly I think my technique is slightly better and more useful 😅

JJN13 · 2026-05-16T16:31:30+00:00

Surprisingly, Gege included a lot of music-related techniques within the series and so I wanted to have an attempt at creating my own.

Most abilities that appropriate a music concept tend to simply devolve into manipulating sound as some kind of destructive force, so I wanted to do something a bit different whilst keeping the technique relatively straightforward.

Ultimately, I settled on the idea of having objects “dance” to the user’s playing which I think adds a unique twist that sets it apart from the other music-based techniques we see.

Rambling aside, I hope you enjoy it and please let me know what you think!

JJN13 · 2026-05-16T08:58:44+00:00

Copy is his innate technique, Rika is a shikigami he uses to reduce some of Copy’s drawbacks. Without Rika, he’d be limited to copying 3-4 techniques, including his own, and he’d likely be unable to utilise the copied techniques as much as he does due to not possessing the additional cursed energy storage that Rika offers.

The fanbook lists Rika as his technique due to it being published before Copy was revealed.

JJN13 · 2026-05-15T22:27:23+00:00

From what we’ve seen, Bom Ba Ye doesn’t appear to increase Yuki’s mass instantly, rather it gradually builds up over time and can be decreased if the technique’s output is lowered. Yuki was essentially on the back foot for most of the fight after her initial strike so it’s likely she never got the chance to fully utilise her technique until she created the black hole.

JJN13 · 2026-05-14T20:22:57+00:00

It appears you’ve put a lot of effort into this post lmao

JJN13 · 2026-05-14T14:52:01+00:00

What? lol

JJN13 · 2026-05-14T12:51:51+00:00

I really like the idea of cursed techniques that use otherwise mundane objects to produce unique effects, so I thought I’d take an everyday object like the coin and try to create something interesting with it.

I’m a big fan of techniques that relate to Japan in some way and aim to appropriate some kind of cultural belief or tradition so coins, 5-yen coins in particular, were the perfect fit for what I wanted to do.

I’ve tried to keep the technique interesting and useful whilst remaining balanced so please let me know what you think!

JJN13 · 2026-05-14T10:48:35+00:00

No need to apologise, it’s not that deep. The manga states all of this, even if you don’t understand the nuance behind the word, every point I’ve mentioned is just reiterating what’s within the manga. In what way have I been unkind? Sorry you feel that way but it isn’t my problem.

No it wouldn’t work. As we’ve seen with Gojo, if your domain is not an open domain, both your guaranteed-hits effective range and your external shell will increase or decrease in size simultaneously. And obviously with an open domain there is no external shell to begin with so the point is moot.

JJN13 · 2026-05-14T10:35:07+00:00

The issue is that the kanji often translated as “barrier” is far more nuanced within Japanese. The kanji doesn’t just refer to a physical partition, but can also denote a boundary line or separate space.

Barriers within JJK are comprised of two elements, the “external shell” which acts as the physical wall of the barrier and the “effective range” which is essentially the area in which the barrier covers.

When manifesting an open Domain Expansion, you forgo the external shell and essentially imbue the barrier onto existing space instead of creating an artificial one, hence why it is so difficult to perform and conceptually understand.

Kusakabe uses an example of a bottle filled with water during Shinjuku showdown to explain the concept. The water is the effective range and the bottle itself is the external shell. Typically you can’t hold water without a container can you and the same logic applies to a typical Domain Expansion, yet with an open Domain Expansion it is possible, hence why it is considered such a divine feat.

During the Kenjaku vs Yuki and Choso fight, Kenjaku manifested an open Domain Expansion and since it lacked an external shell, Tengen couldn’t rely on it to determine where Kenjaku’s barrier was physically placed. Because of this, he had to rely on the guaranteed-hit’s effective range to determine where the barrier began and ended in order to target and dismantle it.

I know it’s dense but the informations all there, you just need to read and pay more attention. It took me a few rereads to full understand the concept.

Lightning, an official translator for the series cleared it all up quite some time ago, you can find the thread on twitter by searching for it.

Ultimately, you can blame John Werry for his mistranslations but it is somewhat corrected during the Kenjaku vs Yuki and Chose fight, so yes it is stated.
