dBu - 忌憚騒命曲 ～ Demon tale sonata (Hartmann's Youkai Girl) 

What have you done, Jack Black. Now this is like Lunatic Princess, no actual Touhou comments even though this is a Touhou song

"Philosophy of an 8-Sided Person"

Great song, I love that music box part around 4:00. And of course, mandatory mentioning of octagons.

THE GLOOMY POWER OF OCTAGON.

毎日聴くほど気に入った

不安になってくるこの感じが良い

I wanna be the Destination 　のラスボスのBGMじゃないか！！

8 awesome angles brought me here

14年前なのにこんなかっこいい曲作れるのか、、

love how most of the english part of the comment section is either some octagon joke i dont know of, or I wanna be the destination

Ok Koishi I see the stop sign but I have to find an Octagon. If I stop how can I find an octagon? HOW KOISHI HOW.

Hey, how's it goin'? I'm Jack. And today, i'm here to tell you about the word octagon. Now octagon is an amazing shape with 8 fantastic sides and 8 awesome angles. Here, let me show you. *looks around* Oh no. *looks again* Oh MAN!

かっこ良すぎる！！ 良いアレンジだ！

神曲スギィ！！！！！！

I wanna defeat the crasy destinationのボスの使用曲ですね(棒)(トラウマ)

I'm in love with these arrangements.....

Hartmann's Youkai Octagon

かっこいい

白　玉　王　子

Koishi on the picture looks so innocent until you face her true self

this remix of this song made me love it, and now i can't find enough of it on youtube xD dBu has some REALLY good stuff

At the start, I heard like a "MAN!" from the background... Is Jack Black cursing this song?

Why is everyone talking about an Octagon in a Touhou remix??

i wannaのどっかのボスにこの音楽あったな。

Octagons...are fucking everywhere...

So good

THAT'S WHY I REMEMBER THE SONG

探していた名曲

AWW MAN! I TOTALLY FORGOT TO BRING AN OCTAGON!

"my name is koish and i am a wizerd" ...yes. yes you are *MOST DEFINITELY* a wizerd, you little cutie, Koishi~

Why I keep hearing "Oh Man" and "Octagon" here?

Happy New Year

The song is international!

I love dBu. That is all.

o tema da Koishi é o retrato exato do meme "Perai tem coisa errada"

オルゴールんとこ最高すぎ

Love hearts everywhere ~♥

Octagons and this song was in my childhood.

@sesshii Koishi always smiles

This reminds me of my elementary school student's term.

Wow

why are there so many comments about octagons?

Well I've seen the octagons too but DoubleSAnimations brought me here :P

I'm the only one who thinks this is perfect for a RPG/3rd Person action Battle D:?

Hell yeah

There is an ad on the side about 2 dogs from Japan that have heart shaped spots on their body, first thought "Koishi had something to do with this..."

2:55 what you came here for

Thanks Jack black, im here from the 8 sides of youtube to listen to some zunes

*Insert 8-sided Polygon Joke here*

If I stop replaying the video how will I find an octagon?

beatstream!

he/she grabbed it from when Invader Zim was being invaded by another Irkin and went "YOU'RE AFTER MY ROBOT BEE! D:" and hid the robot bee behind his back.

How about we keep her with Yoshika, 'kay? I always found Yoshika's theme fitting for Hsien Ko in Marvel Vs. Capcom 3 anyways.
