End of reason

is a song by εpsilonΦ.

It was announced in December 4, 2020 as one of the original songs that would be in AAside since its release. And wasn't made public until the game's release in January 14, 2021 along with the Tadaomi Kurama focused song quest "Insanity of reason". There, it was described as "At Shu's whim, Tadaomi writes the lyrics for this song while pursuing what 'Flightless bird' means."

A digital single version was released on March 13, 2021 to celebrate white day.

It is written by Shirasagi Yuki, composed by Koutetsu Aniki -who also played the guitar-, and arranged by Koutetsu Aniki and Hijiki Shinki -who was in charge on the additional programing-; the bass was played by Tatsuya Doi (HANO) and the drums by RYOTA.

Lyrics
Romaji= Kabe no sora ga ochiteku Usui kokyū togiresō Haida tsubasa bara maita yo

Soshite nani mo shirazu ni Gakeppuchi no hinadori wa Yume ni michita hajimari e to...

Kizutsuketai sono kokoro wo Soshite motto ai Kakimazetara namete ageru Sono namida mo sube Kurutteyuku kono kokoro wa Tomerarenai I Usurete yuku ishiki no naka Motometsudzuketeru

Yubi no sukima surinukeru Aseta yume no zankyō ni Torawareteiru ā hinadori wa

Tobitatsu ima sono toki ni Hantenshita ten to ji ga Tatakitsukeru genjitsu to kage

Akaku somaru kono tsubasa ga Yokotawatte nai Aishiteru yo boku no meroa Nidoto aenai ke Wasurenaide wasurenaide Ano keshiki wo... do not Yugamu kao to kono hitomi ni Michitariteku crazy

Miageta sora utsukushī... (nazena no ka...) Kakechigaeta sutōrī wa (zankoku da) Negau koto mo kanawanai (torikagu de) Nogarerarezu oborete... (akogare ni)

Akaku somaru kono tsubasa ga Yokotawatte nai Aishiteru yo boku no meroa Nidoto aenai ke Wasurenaide wasurenaide Ano keshiki wo... do not Yugamu kao to kono hitomi ni Michitariteku crazy Kanji = 壁の空が　落ちてく 薄い呼吸　途切れそう 剥いだ　翼　バラ蒔いたよ

そして　何も知らずに 崖っぷちの雛鳥は 夢に満ちた　はじまり　へと…

傷つけたい　その心を そしてもっと　愛 掻き混ぜたら　舐めてあげる その涙も　すべ 狂ってゆくこの心は とめられない I 薄れてゆく　意識の中 求め続け　てる

指の隙間　すり抜ける 褪せた夢の　残響に 囚われている　あぁ　雛鳥は

飛び立つ　今　その瞬間に 反転した　天と地が 叩きつける　現実と影

紅く染まる　この翼が 横たわって　嘆[な]い アイシテルヨ　ボクノ　メロア 二度と　逢えな　いけ

忘れないで　忘れないで あの景色を…　do not 歪む表情[かお]と　この瞳に 満ち足りてく　crazy

見上げた空　美しい…　(何故なのか…) 掛け違えた　ストーリーは　(残酷だ) 願うことも　叶わない　(鳥籠で) 逃れられず　溺れて…　(憧れに)

紅く染まる　この翼が 横たわって　嘆[な]い アイシテルヨ　ボクノ　メロア 二度と　逢えない　け 忘れないで　忘れないで あの景色を…　do not 歪む表情[かお]と　この瞳に 満ち足りてく　crazy English = The sky beyond the wall falls The weak breath is interrupted The ripped wings are scattered

And the ignorant baby bird Standing in the edge Is bound to a dreamlike beginning…

I want to hurt that heart And give it more If it starts shaking, I’ll lick Your tears and This heart that’s being driven crazy Won’t stop, I In this vanishing conscience, I’ll keep searching

Ah, a baby bird who’s trapped In the echoes of a dream That slips through my fingers

Now, in the moment of takeoff, Sky and earth are upside down And hit by both reality and shadows

These wings dyed in red Will spread on the floor I love you so, my Meloa Even though we won’t Don’t forget it, don’t forget it That scenery… Do not When I look at that distorted face My eyes are satisfied by a crazy

The sky I looked up at it’s beautiful… (I wonder why) This mistaken story is (so cruel) I won’t obtain what I desire (inside the cage) Without escape, I’ll drown… (In longing)

These wings dyed in red Will spread on the floor I love you so, my Meloa Even though we won’t Don’t forget it, don’t forget it That scenery… Do not When I look at that distorted face My eyes are satisfied by a crazy
