Letra de ' Sumi Kuroi Shiro ' de Irokui

Shikakui sora ni tatte kuchibiru ugokasu. dare no mimi ni mo fusagu kikai ga
Sukoshi fushizen ni natte mawari miwataseba haki tsubushita kutsu no ashioto

Narabu toshokan ni mushikui darake no peeji wo yabuite suteta.
Kuru shimagire ni kidukeba jibun mo nakama ni natteru.

Shikakui sora ni tatte kuchibiru ugokasu. jikan to yokubou ni shihai sarete wa
Kizu darake ni natte dareka ni sugaritsuku yo... kono machi wa sukoshi mabushi sugiru.

Nemuri, gomakasou to atama no okufukaku nagai kugi ni utarete wa me wo samasu asa.
Kiduku to, makura wa nureteru

Tetsu no machi no naka tada bouzento hitori

Kiri yozora ni te wo kasane, jibun e uta wo utau yo.
Suraido shite yuku kitanai akari mo yukkuri sono hi wo toikakeru.
Meikyuu no yoru wa akete yuku

Shikakuku sora kakotte kuchibiru wa damaru. boku no mimi ni wa nanimo kikoenai.
Gaitou miagereba, tamaru chou mitai ni gaichuu (mushi) yori kirei ni mieta dake de

Jibun, gomakasou to tada heya ni kakurete koutetsu ni karada wo gitai.
Nigeru koto de shika arienai naraba kiete shimaitai...

Tetsu no machi no naka, tada bouzento hitori kiri yozora ni te wo kasane, jibun e uta wo utau yo.
Suraido shite yuku kitanai akari mo yukkuri sono hi wo toikakeru.
Meikyuu no yoru wa fukete yuku

Tetsu no boku no naka, hito shizuku dake tada afureta jetto burakku no namida wa mou nani mo somaru koto wa nai, mou nani nimo somaru koto wa nai kara...
