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."

It is written by Shirasagi Yuki, composed by Koutetsu Aniki -who also played the guitar-, 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.

A digital single version was released on March 13, 2021 to celebrate white day. It is also included on their first album Friction, which was released on September 21, 2022; and on the third disc of the Argonavis AAside Memorial Album, which will be released on April 12, 2023.

Lyrics
Romaji= Kabe no sora ga ochiteku Usui kokyuu togiresou 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 zankyou ni Torawareteiru aa 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 utsukushuu... (naze nano ka...) Kakechigaeta sutoorii 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 (もう飛べないの？) 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… (ねぇ　教えてよ)

もう　嫌だ　無謀な　(逃亡) こうなった　原因は　(なんだ？) 存在の　後悔を　(するの？) 最低な　禁断の　(症状)

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

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 (何を見てるの？) 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 (傷みを抱いて)

後悔は　後世への　(転生) 恩恵は　延命じゃ　(ないね) 勝算はあったんだ　(少年) 散々な　運命の　(証明)

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

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

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　(テル…) アイシテルヨ　ボクノ　メロア 二度と　逢えない　け(レド…) 忘れないで　忘れないで あの景色を…　do not (forget) 歪む表情[かお]と　この瞳に 満ち足りてく　crazy (emotion) English = The sky beyond the wall falls The weak breath is interrupted The ripped wings are scattered (Won’t they fly anymore?) And the ignorant baby bird Standing in the edge Is bound to a dreamlike beginning… (Hey, tell me)

I don’t want any more pointless (flights) Why did it all turn out (like this?) Your existence, do you (regret it?) The worst forbidden (symptom)

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

Ah, a baby bird who’s trapped In the echoes of a dream That slips through my fingers (What is it looking at?) Now, in the moment of takeoff, Sky and earth are upside down And hit by both reality and shadows (Embrace the pain)

Regret is other life’s (reincarnation) The goal is living more (it isn’t) You could’ve won it (Young boy) Fate’s complete (proof)

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

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 (and cry) I love you so, my Meloa Even though we won’t (meet again…) Don’t forget it, don’t forget it That scenery… Do not (forget) When I look at that distorted face My eyes are satisfied by a crazy (emotion)
