Cosmic Princess Kaguya! Insert Song Lyrics





Happī Shinsesaiza Kimi no mune no oku made
+
Todoku yō na merodi kanaderu yo
+
Hakanaku chitta awai kataomoi
+
Warai hanashi da ne ima to nareba
+
Miru mono subete kagayaite mieta
+
Ano hibi ga kirei ni waratteru yo
+
Gaman suru koto dake oboenakya ikenai no?
+
「Otona ni natte chōdai ne?」
+
Naranakute ii yo
+
Shiranai koto bakari shiranai nante ienakute
+
Taihen oniai de
+
Usotsuite gomen ne
+
Happī Shinsesaiza kimi no mune no oku made
+
Todoku yō na merodi kanaderu yo
+
Tsumaranai 「tatemae」 ya yana koto zenbu
+
Keshite ageru kara kono oto de

Kokoro odoraseru kazararanai kotoba

Sukoshi dakedo dekiru koto

Chotto tereru yō na tanjun na kimochi

Happy Synthesizer, to the depths of your heart
+
A melody that reaches your heart, I'll play
+
A fragile, fleeting crush that vanished
+
It's a joke now, isn't it?
+
Everything I saw seemed to shine
+
Those days are smiling brightly
+
Do I have to learn only to endure?
+
"Please grow up, okay?"
+
You don't have to.
+
There are so many things I don't know; I can't say I don't know
+
"It suits you very well"
+
Sorry for lying
+
Happy Synthesizer, to the depths of your heart
+
A melody that reaches your heart, I'll play
+
All the boring pretenses and all the nasty things
+
I'll wipe them away with this sound
+
[thanks for visiting animesonglyrics.com]
The one thing I have, though I have no notable talents
+
Even if it's just a little, there is something I can do
+
Words that make my heart leap, unadorned
+
I'll convey them with electronic tones
+
Happy Synthesizer, see, it's going to be fun
+
A melody that wipes away tears, I'll play
+
You don't have to pretend to be strong, you know?
+
It's fine to be honest with yourself
+
The one thing I have, for a guy with no notable talents
+
Even if it's only a little, there is something I can do
+
A simple feeling that makes me a little shy
+
I'll convey it with electronic sounds

ハッピーシンセサイザ 君の 胸の奥まで
+
届くようなメロディ 奏でるよ
+
儚く散った淡い片思い
+
笑い話だね 今となれば
+
見る物全て 輝いて見えた
+
あの日々がキレイに 笑ってるよ
+
我慢する事だけ 覚えなきゃいけないの?
+
「大人になって頂戴ね?」
+
ならなくていいよ
+
知らない事ばかり 知らないなんて言えなくて
+
「大変お似合いで」
+
ウソついてゴメンね
+
ハッピーシンセサイザ 君の 胸の奥まで
+
届くようなメロディ 奏でるよ
+
つまらない「たてまえ」や ヤな事全部
+
消してあげるから この音で
+
何の取り柄も無い 僕に唯一つ
+
少しだけど 出来る事
+
心躍らせる 飾らない 言葉
+
電子音で伝えるよ
+
ハッピーシンセサイザ ほらね 楽しくなるよ
+
涙拭うメロディ 奏でるよ
+
強がらなくたっていいんじゃない? 別に
+
自分に素直になればいい
+
何の取り柄も無い 僕に唯一つ
+
少しだけど 出来る事
+
ちょっと照れるような 単純な気持ち
+
電子音で伝えるよ

In the near future, 17-year-old Ayaha Sakayori, a high school student at a top Tokyo school, balances a hectic life of classes and part-time jobs. Her only escape is watching the streams of Yachiyo Tsukimi, a popular virtual performer and administrator of the online world Tsukuyomi.

One day, Ayaha discovers a glowing, rainbow-colored gaming pole—and finds an adorable baby emerging from it. She takes the child home, only to watch her rapidly grow into a girl Ayaha’s own age. “Could you be Princess Kaguya?” she wonders.

The mischievous Kaguya demands Ayaha’s help in Tsukuyomi, where Ayaha produces music and Kaguya performs as a streamer. As the two grow closer, a dark presence looms—threatening to drag Kaguya back to the Moon. This is the tale of Princess Kaguya as never seen before.
