Bài hát: Hello, World! (Kekkai Sensen Opening) - Bump Of Chicken
Tobira hirakeba nejireta hiru no yoru
Kinou dou yatte kaetta karada dake ga tashika
Ohayou kore kara mata maigo no tsudzuki
Minareta shiranai keshiki no naka de
Mou dame tte omotte kara wari to nandaka yarete iru
Shinikira nai kurai ni joubu nani ka chotto hazukashii
Yarubeki koto wa wasurete ite mo wakaru
Sou shinai to totemo kurushii kara
Kao wo agete kuroi me no hito
Kimi ga mita kara hikari wa umare ta
Eranda iro de nutta sekai ni kakomarete
Erabenai kizu no imi wa doko darou
Go jibun dake ga hiiro sekai no mannaka de
Owaru made de zuppari suteeji no ue
Dou shiyou karappo no furi mo deki nai
Hello doumo boku wa koko ×2
Oboete shimatta kankaku omoi de to wa chigau tagui
Motto namida no soba ni atte itsumo shinzou tsukamarete ite
Juubun rikai dekite iru zutto sore to issho
Sou janai to nani mo mienai kara
Iki wo tsunagu ikiru tsuyoi hito
Tomaru kokoro wo hikizutte tsurete kita
Fusai da mimi de kiita niji no you na melody
Kudakenai omoi ga uchigawa de utau
Kakurete itatte hiiro mamoru mono ga aru
Kowai no wa sore hodo kidzuite iru kara
Tobira hirakeba nejireta honto no uso
Karappo no furi no furi karada dake ga tashika
Ohayou ima demo mada saigo no tsudzuki
Sakebou soko kara doumo boku wa koko
Saa me wo akete kimi wa tsuyoi hito
Sono me ga mita kara subete wa umareta
Eranda iro de nutta sekai ni kakomarete
Erabenai kizu no imi wa doko darou
Go jibun dake ga hiiro mamotta mono ga aru
Kowai no wa sono kachi wo shitte iru kara
Fusai da mimi de kiita niji no you na melody
Kudakenai omoi ga uchigawa de utau
Himei wo ageta hiiro sekai no mannaka de
Owaru made de zuppari jibun ga mite iru
Dakara mou shinda furi mo imi nai
Hello doumo boku wa koko ×4
