Pretty Queen Lyrics

Pretty Queen
Nee doko ni iru no?
Nozoki konda kagami koshi no shoutai

Machi kado de miushinatta
Yume no tsuzuki otte sagashiteiru no sa
Miss Pretty Queen
Hagureta shoujo
My Little Days
Togiretta RESPONSE
Miss Pretty Queen...

Pretty Queen
Saa me wo samashite
Garasu no kutsu wo kette hadashi de tobira wo kett.

Kono sekai wo itsumo baby
Sono tenohira no ue mawashiteita janai?
Miss Pretty Queen
Toki ni wa SELFISH
My Little Pride
Bukiyou na PASSION

Miss Pretty Queen oh...
Miss Pretty Queen oh...

BASU kara oritara MACHINE GUN wo buppanase*
Chiisana HEART ni hi wo tsukero!

Pretty Queen
Yuka ni kobore ochita
Namidairo no PEARL tsunagi awase

Surikireta SKIRT sotto
Hiroge mune wo hatte habatakeba ii
Miss Pretty Queen
Hagureta shoujo
My Pretty Queen
Kagami no naka
Miss Pretty Queen...
