Sou - Q.E.D. Lyrics
The Case Book of Arne Opening Theme Lyrics
Quod erat demonstrandum demons
Quod erat demons
Karappo na utsuwa ni
Semarikuru yami no hou e
Saa! Osorezu shoumei o shiyou
Sakkaku to asoberu you ni
Who am I? I am who I am
1tsu dake tashikana shinjitsu ni semaru
Chi ga kayou te to papetto ga kasanatte shoutaimu
Fujunbutsu ga nakunareba
Hontou no sugata datte wakaru darou ka?
Odore kono yoru ni are you ready?
Azakana seimei mure makichirashite
Odoriko no yoru ni Q.E.D.
Fikushon no you na yami to kyouki no aida de
Nee meimei shoumei ima kakushin o
Hora kimi no inochi ga abaku kara
Quod erat demonstrandum demons
Quod erat demons
Quod erat demonstrandum demons
Quod erat demons

Wazuka ni hiraita
Osoukuru yami no hou e
Saa! Osorezu kyuumei o shiyou
Saigo no ishi o tsugeru you ni
Who am I? I am who I am
1tsu dake tashikana shinjitsu e semaru
Makkana hana ni somatta kenshin no shoutaimu
Higenjitsu o ukeirete
Owari made shouki de ireru darou ka?
Odore kono yoru ni are you ready?
Shinsou ni seimei afure makichirashite
Odoriko no yoru ni Q.E.D.
Fikushon no you na
Yami to shouki no aida de
Nee meimei shoumei ima kakushin o
Hora boku no te ga tsukamu kara
Quod erat demonstrandum demons
Quod erat demons
Quod erat demonstrandum demons
Quod erat demons
That which was to be demonstrated, demons
That which was demons
Into the empty vessel
Towards the looming darkness
Come on! Fearlessly, let us prove it.
So we can play with illusions
Who am I? I am who I am
Approaching the one certain truth
The blood-flowing hand and the puppet overlap-showtime
If impurities disappear
Will we be able to know the true form?
Dance in this night, are you ready?
Spread vivid life all around
On the dancer's night, Q.E.D.
Between darkness and madness, as if it were fiction
Hey, perplexing proof, now to the core
For your life will reveal it
That which was to be demonstrated, demons
That which was demons
That which was to be demonstrated, demons
That was demons
[thanks for visiting animesonglyrcs.com]
Slightly opened
Towards the encroaching darkness
Come on! Fearlessly, let us investigate
So that the final will can be carried on
Who am I? I am who I am
Moving toward the one true truth
The devotion dyed in bright red-showtime
Accepting the unreal
Will we stay sane until the end?
Dance in this night, are you ready?
Life overflows and scatters toward the truth
On the dancer's night, Q.E.D.
Like fiction
Between darkness and sanity
Hey, perplexing proof, now to the core
See, my hand will grab it
That which was to be demonstrated, demons
That which was demons
That which was to be demonstrated, demons
That which was demons
Quod erat demonstrandum demons
Quod erat demons
空っぽな器に
迫り来る闇の方へ
さぁ!恐れず証明をしよう
錯覚と遊べるように
Who am I? I am who I am
1つだけ確かな真実に迫る
血が通う手とパペットが重なってショータイム
不純物がなくなれば
本当の姿だってわかるだろうか?
踊れこの夜に are you ready?
鮮やかな生命塗れ撒き散らして
踊り子の夜に Q.E.D.
フィクションのような闇と狂気の間で
ねぇ迷迷証明 今 核心を
ほら君の命が暴くから
Quod erat demonstrandum demons
Quod erat demons
Quod erat demonstrandum demons
Quod erat demons
[アニメソングリリックスのご利用ありがとうございます]
僅かにひらいた
襲いくる闇の方へ
さぁ!恐れず究明をしよう
最後の意思を継げるように
Who am I? I am who I am
1つだけ確かな真実へ迫る
真っ赤な花に染まった献身のショータイム
非現実を受け入れて
終わりまで正気でいれるだろうか?
踊れこの夜に are you ready?
真相に生命溢れ撒き散らして
踊り子の夜に Q.E.D.
フィクションのような
闇と正気の間で
ねぇ迷迷証明 今 核心を
ほら僕の手が掴むから

Description: Opening Theme
From Anime: Arne no Jikenbo (アルネの事件簿)
From Season: Winter 2026
Performed by: Sou
Released: 2026
“There are two kinds of people in this world: those who believe in the existence of inhuman beings… and those who don’t.”
Luis Hartmann lost his father, a detective, to a string of murders, leaving him completely alone in the world.
Rumor has it that the crimes were committed by the “Grave-Digging Vampire,” but Luis, who does not believe in superstitions, resolves to catch the culprit with his own hands.
Then appear Arne Nointäter, who calls himself a detective, and his assistant Lin Reinweis.
Before Luis, a new door is about to open—
