Sora o kiku kaze wo miru itsu no ma ni ka wasureteru 
  Soko ni aru shiawase ni kagi wo kakete iru 

  Suberikomu chikatetsu no naka wa kikazatta muhyoujou 
  Dare mo sakebanai kishimu REERU nokoshite 

  * Nukedasenu joutai sobietatsu shougai kakezurimawari sagasu 
  (key of life) 
  Kakaeteru mondai SUTORESU wa boudai hane naki tsubasa de fly 

  Kioku no naka no mirai ni te ga todoita hazu na noni 
  Koko ni kuru made no jikan nani ga dekita kana 

  Yoku aru hanashi to nagusamete yosouzu wo kakinaosu 
  Doko ni itemo nodo ga kawaite bakari 

  ** Usure yuku sonzai sarakedasu shuutai kono te de tsukamitoru 
  (key of life) 
  Owaranai haikai doki ni aru jun'ai atenaki ashita ni try 

  Tsuzukanai nintai tomedonai shinpai kakezurimawari sagasu 
  (key of life) 
  Tameiki de manpai kimi dake wa zettai hane naki tsubasa de fly
