Bài hát: Nirvana (Inu X Boku Ss Op) - Mucc

Kowareta sekai no sumikko de Bokura wa sora wo miageteru
Kimi no nukumori wo sagashi ni Yuku yo

Tada te wo nobashiteta Ikiba mo nai kuse ni
Sabishisa kakushite Tesaguri de aruku
Kimi ga inai yoru ni Hajimete kanjita
Kokoro no naka no itami

Kowareta sekai no sumikko de Bokura wa sora miageteru
Kimi no nukumori wo sagashi ni Yuku yo

Kankaku ga nibutteiru? Namida wa afureru no ni
Kono kimochi tte nan dakke? Dokoka ni wasureteru.
Saa, mondai wa kono kesenai EREKUTORORAITO
Kokoro no naka no Akari

"Aitai" to DOA wo tataite Boku wa shiranai FURI wo shita
Asu ni nareba kono itami mo Umi no mukou e shizumu?

Kowareta sekai no sumikko de Bokura wa sora miageteru
Kimi no nukumori wo sagashi ni Yuku yo

Tsunaida sono te no binetsu ga Kienai akari wo tomoseba
Boyaketa sekai no sumi made Terasu Hora Azayaka ni

Kanashimi wa shizumi Hora Yo ga akeru
Kimi to nukumori wo sagashi ni
Yukou Mada minu Sekai e to
