Bài hát: Shirushi (C3 OST) - Eri Kitamura

Sasayaku kaze no ne no shirabe shigure no kokoro wo sarai kagu
Sukashita konpeki no sora wa kikyou iro ni kawaru no

Utsurou maboroshi wa kakuen toshite idzu
Yorisoeru tsuioku to tomoni megurase

Kasaneta tomohishi no omoi wa tadori kita michi no shirube
Ikusokubaku no kotonoha yori mo hitotsu no shirushi
Kakedasu ashioto wa haruka tokoshie no tone he
Matoitta rasen no chikai wo kono ryoute de kizamikonde yuku

Hajiketa minawa no inochi ni shizuka na kokoro mo uchi nabiku
Tanabiku usu ao no kumo wa toki-iro no yuuzora ni

Yurameku kurenai wa hodasu kakoi wo nuke
Yumeutsutsu no hazama wo tobikoete yuke

Kasaneta tomohishi no omoi wa tadori kita michi no shirube
Ikue no oriiroha yori mo hitotsu no shirushi
Hajimari no hitomi no oku wa saihate no mukou he
Matotta tashika na chikai wo kono ryoute de kizamikonde yuku

Oboroge na kumoi ni hibiku ikusen no koe
Minamo ni utsushita kohaku no negai
Kage fumi yori saki de yadoshite mate
Amatsu sora yo

Tsuranuku tomohishi no omoi wa tsumugi yuku michi no shirube
Ikusokubaku no kotonoha yori sou hitotsu no shirushi
Kakedasu kodou wa haruka na tokoshie no tooto he
Matotta subete no chikai wo kono karada de kizamikonde yuku
