秘密ノ金魚 (Himitsu no Kingyo)

Background
The Girl didn't show people her treasure except for her close friend. It's a little promise between the best friends.

"It's because we're friends"

A song about a closeted lesbian couple. They show their secrets to one another.

It will be featured on masa's ALCATRAZ, along with the rest of the "Story of Secrets" series.

Lyrics
''Note: one of the spreading misconceptions about this song is "in Japan a goldfish is put into a cardboard box and buried when it dies", but there is no such custom in Japan. This tradition comes from Noëlle McHenry's mistranslated subs and description.''
