Another SH translation by me. This is probably their shortest song. How lazy am I.

珊瑚の城
sanko no shiro
Castle of coral

－彼らは待ち続ける　輪廻が砂時計を反転させる瞬間を－
-kare wa machitsuzukeru ninne ga sunadotei wo hantensaseru shunkan wo-
-We continue to wait. For endless cycle, the instant which overturn the sandglass-

蒼く冷たい海の中、泡沫の夢を見る
aokutsumetai umi no naka, utakata no yume wo miru
In the cold blue sea, I see bubble of dream.
忘れ去られた追想は　揺れながら錆びてゆく
wasuresarareta tsuisou wa yurenagara sabiteyuku
The forgotten reminiscence is unable to move and it rusts.

珊瑚が眠る樹海へと　楽園は堕とされた
sanko ga nemuru jukai eto rakuen wa otosareta
Into the sea of trees where coral sleeps, the paradise was fallen.
扉を護る番人は　石のように動かない
tobira wo mamoru bannin wa ishi no you ni ugokanai
The guard who is protecting the door does not move like a stone.

会いたくて…愛しい人の名を
aitakute…itoshii hito no na wo
Because I want to meet… My beloved person’s name,
叫んでも 声は届かない
sakendemo koe wa todokanai
Even if I scream, my voice will not reach.

閉ざされた…城は死者の檻
tozasareta…shiro wa shisha no ori
Closed… The castle is the jail of the dead.
タナトスは 彼を逃がさない・・・
tanatosu wa kare wo nigasanai…
Thanatos will be not released…
