Lyrics
手に入れいれられないのなん> 戦い疲れ果てたコロニー　貴方が欲しい
 * -|Japanese=愛のイロハを学んでも

(If you do)なんだって怖くないから (If you will)背中を任せて

壊したい　壊してしまいたい　貴方のためなら 不純も矛盾も見境なんてない 守りたい　守りたいのは全てを 教えてくれた　貴方だけ

目には目を歯を　尖っても 伝えられないの　でも 悲しむ顔は負けなセオリー　素直でイタイ

(If you do)失っていいような未来 (If you will)端から見えていない

壊したい　壊してしまいたい　貴方のためなら 不順も矛盾も見境なんてない 隠したい　隠したいのは全てを 背負うと決めた　涙だけ

背伸びして見える世界 貴方のため？　自分のため まだわからない　感情の裏側

壊したい　壊してしまいたい 戻れないのなら 尚更強く抱きしめていたい 離れない優しさを消し去っても 悲しいくらい　溢れ出る思い

逃げない　逃げたくないこのジレンマから 不順も矛盾も見境なんてない 守りたい守りたいのは全てを教えてくれた 貴方だけ Te ni ireirerarenai no nan no Tatakai tsukare hateta koronii anata ga hoshii
 * -|Romaji=Ai no iroha wo manande mo

(If you do) Nan datte kowakunai kara (If you will) Senaka wo makasete

Kowashitai kowashite shimaitai anata no tame nara Fujun mo mujun mo misakai nante nai Mamoritai mamoritai no wa subete wo Oshiete kureta anata dake

Me ni wa me wo ha wo togatte mo Tsutaerarenai no demo Kanashimu kao wa makena seorii sunao de itai

(If you do) Ushinatte ii you na mirai (If you will) Hana kara miete inai

Kowashitai kowashite shimaitai anata no tame nara Fujun mo mujun mo misakai nante nai Kakushitai kakushitai no wa subete wo Seou to kimeta namida dake

Senobi shite mieru sekai Anata no tame? jibun no tame Mada wakaranai kanjou no uragawa

Kowashitai kowashite shimaitai Modorenai no nara Naosara tsuyoku dakishimete itai Hanarenai yasashisa wo keshisatte mo Kanashii kurai afurederu

Omoi nigenai nigetakunai kono jirenma kara Fujun mo mujun mo misakai nante nai Mamoritai mamoritai no wa subete wo oshiete kureta Anata dake I can't obtain it An exhausted colony from battle, I want you
 * -|English=Even if I learn the A B C's of love

(If you do) I am not afraid of anything (If you will) leave it up to me

I want to destroy, I want to destroy it if it's for you Impure or paradox, I don't care at all I want to protect it, The only thing I want to protect is you who taught me everything

Eyes for eyes, sharpen your fangs I can't tell you my feelings, but If you show your sad face, you lose I want to be honest

(If you do) the future that's ok to lose (If you will) I don't want it from the beginning

I want to destroy, I want to destroy if it's for you Out of orders or paradox, I don't care at all I want to hide The only thing I want to hide is the tears I shed when I decide to carry everything on my back

The world that seems to be stretched Is it for you? Is it for me? I still don't know, what's behind this feeling

I want to destroy, I want to destroy If I can't go back I want to keep holding you tighter even more Even if I get rid of the kindness I can't forget The feeling is overflowing, and it's making me sad

I won't run away, I won't run away from this dilemma Out of order or paradox, I don't care at all I want to protect it, The only thing I want to protect is you who taught me everything
