My personal favourite, Satori

Parsee

Parsee

Meiling

Cirno's is fittingly simple

Very nice.

Last one, Chen's. The only other one better than this is Suwako's, but I haven't done that yet.
I think I'm going to print out Satori's on sticker paper, myself.
Cheers.

The sigils are taken from royalty free art online. It would be easier to just try find the originals.

oops

>>17488740
That's really cool, anon.
Though, if you don't mind, I would really appreciate it if you could post these with a transparent background.

>>17488829
Sure. Not sure why I didn't think of this before posting.

I didn't make the white bits inside Marisa's and Parsee's transparent because 1. it would be a lot of work and 2. I don't think they'd look good transparent. A flat color, maybe.

If I marry Sanae maybe my mom will stop kvetching about settling down with a nice Jewish girl

>>17488763
Thank you for that one. I'd been meaning to get this done myself.

>>17489219
Marry Renko instead if Sanae isn't your type.

These are quite interesting, from the symmetry point of view.
>>17488740
There actually aren't any symmetries for this one. The outside star has the same symmetry group D_6 as the hexagons while the inside has that of the square, D_4. The catch is that if the displacement angle of the square in the middle from the principle axis (y axis, say) is not an integer multiple of the internal angle of hexagon minus that of the square (modulo 2pi), then the symmetry group is trivial, with only the identity e in it.
>>17488746
Here we can find 4 axes of symmetry, making the symmetry group D_4. Also one thing that's very interesting is that this is an n = 1 framing of two Hopf links Hopf-linked together, which can be characterized by the trace of twists c_{c_{ij}c_{ji}}c_{c_{ji}c_{ij}}c_{c_{kl}c_{lk}}c_{c_{lk}c_{kl}} in the ribbon category.
>>17488749
The symmetry group here consists of no reflections (due to the braiding pattern) but only rotations by pi/3 This makes the symmetry group the cyclic group of order 6, i.e. Z_6. I don't see any way that we can isotopically make the pattern recover the full D_6 symmetry.
>>17488751
There are only 2 axes of reflection and rotations by pi, which makes the symmetry group D_2.
>>17488757
The symmetry group is the same as that of the triangle, D_3.
>>17488763
This one is D_6.
>>17488767
Similar to Sanae's case the symmetries for this pattern only consists of rotations in D_4 and no reflections due to the braiding pattern, which makes the symmetry group Z_4. However if the braids were mirrored (so that the ones going over are near each other and the ones going under are far apart) then we recover the full D_4 symmetry.
>>17488770
This is just D_4. Indeed compared to Marisa's case the octagon in the middle has a displacement angle of 0 (mod 2pi) compared to the square on the outside, so the symmetry group is D_4 ∩ D_8 = D_4.
>>17488787
Left as an exercise for the reader.

Are these all by the way? If not please make more, they're very nice.

>>17497346
sounds like somebody is currently taking a group theory course

>>17498109
I don't think the usual group theory course covers ribbon categories.

Where's Remiry's

They're all in the Touhou wiki you mensch

>>17499910
Not in this quality, you mongrel.

>>17499923
Picky picky

>>17488751
Udonge's is pretty cool.

I think Mokou has my favorite sigil in the Grimoire

>>17488749

Eirin's is just a fucking caduceus

This one I did pretty poorly, I'll admit. Actual drawings that aren't patterns suck.

>>17502521
better res

Yamame

...Suwako...

The joke is that a goddess of weapons, iron and war has a sigil that looks like it belongs on a preschool wall, I guess. What are these, anyway, just stuff Marisa doodles?

Youmu. It's off due to being too symmetrical, but it looks alright.

>>17497346
k

How many sacrifices do these summons take?

>>17505437
300ml of blood for each stage 1 boss and you add 50ml more.

>>17505456
That's not enough for Remimi

>>17505456
It takes around a soda can of blood to summon Yuyuko.

Just saying. Prep the feeding bag, we have work to do here.

>>17505540
>soda can of blood
isn't a soda can normally 330ml? Unless you mean Ten Desires Yuyu.

>>17505555
Yeah, she is a stage 1 boss in the most up-to-date canon, therefore it takes 300ml. +30 for larger boobs, ass and a prettier face.

>>17505565
How many ml would it take for stage 6 bosses to have larger boobs, ass and prettier faces?

>>17505588
None. They are already perfect.

I'm not wasting my blood for kuso oppai lolis when I can summon more bosses.

>>17505600
What about Stage 5 bosses, then?

>>17505613
Sanae? Sakuya? Reisen?

Fuck it, lets rob a blood bank instead.

>>17502628
Is this supposed to be semicircles or scallops?

>>17505789
the round ones are pretty solidly derived from japanese heraldry, so it's probably overlaid mutsudomoe and therefore circles

>>17505637
I thought we were talking about goat's blood here.

>>17506086
Don't be silly now and

>>17497346
I think you need to take a closer look at wriggle

Letty
I don't see the winter connection.

>>17505456
What about the protags?

Nitori

>>17509107
This would make a good viking shield.

Nitori with no background

The legendary symmetry otaku

>>17508673
Can't you see the... umm.. round snowflake?

>>17488740
If you would release all these .svgs as a .zip upon completion then that would be really great!

Thank you and keep up the good work!

>>17506122
It's been two days and I'm still waiting for the end of this post...

>>17488740
marisa is great and i agreee

Find the seal of Solomon and you'll control all the 2hus

Hey Anon, could you perhaps trace the sigil of my waifu Mokou?

>>17519033
As you can see, Mokou's sigil isn't really suited for replicating with vector graphics. I'm not planning on doing all of them, I'm skipping this kind.

Sorry.

>>17519184
do Aya's
It's basically that one attack on titan logo but with a leaf and a bird hair instead

>>17519210
nvm wrong image
continue as usual

>>17519184
Got it, what a shame. Best of luck tho.

>>17519184
Is Yuyuko's well suited I wonder?

Not really. Look at it.

Doing for sure:
Alice
Flandre
Orin
Yuugi

Maybe:
Kaguya
Okuu
Patchouli
Remilia
Iku
Komachi
Mystia
Hina

No:
everyone else

If anyone could find some higher-res images it'd help my life out a lot. I'm basically pulling a lot of the finer details out of my ass as it is, since I only have these 150x150 images to go off off. I've looked myself, but no luck.

>>17497346
What do you know about drowning Tails in Sonic the Hedgehog 2?

>>17522103
I can check later if I still have the ancient grimoire scans in my old hdd, Ill upload it then

>>17522432
Pretty funny.

>>17522103
Waiting patiently for Kaguya's.

flanflan

>>17532491
I don't know what's up with those annoying seams. They show up in some programs, sometimes not at all. I'll try to fix it before I upload the zip pack.

>>17532498
There, but the svg is a total mess. Well, probably nobody is gonna try to edit nodes in these anyway, so it's cool.

>>17532555
Graphical aliasing.

>>17532491
Nice. Where is Remi's?

>>17534034
I've actually been working on it concurrently with others, slowly. It's the most work-intensive out of all of the ones I've done because there's nearly no clean symmetry, I've got to do everything by hand, I haven't even gotten started on the flowers in the circle yet. It will probably take another week to finish at the rate I'm going.

>>17488740
>>17534106
頑張ってください！

>>17534106
You can do it Anon, I believe in you!

Hey anon, just telling you that the link on the OP is broken. Keep doing gods work btw.
>tfw my 2hu sigil is too complex

>>17507672
You're right there aren't any reflections there, so the group is just Z_4. There wouldn't be any braidings if that were the case.

>>17534106
do it faggot

>>17488740
Keep up the hard work anon!

Bump.

Don't worry about bumping this thread, I can just make another one when I have more.

>>17550982
Don't tell me what to do.
